Declining health of UK’s population also affecting performance of the country’s national health service, report notes
England’s National Health Service (NHS) is “in serious trouble” due to long waiting times, outdated technology, misallocated resources, and numerous other problems, with dire consequences for the country’s populace. That’s according to a new report by NHS surgeon and former Health Minister Lord Ara Darzi, OM KBE FRS FMedSci HonFREng, who was tasked by the United Kingdom’s new Labor government to investigate the ailing healthcare system. His report may contain lessons for US healthcare—including clinical laboratories—as well.
“Although I have worked in the NHS for more than 30 years, I have been shocked by what I have found during this investigation—not just in the health service but in the state of the nation’s health,” Darzi stated in a UK government press release. “We want to deliver high quality care for all but far too many people are waiting for too long and in too many clinical areas, quality of care has gone backwards.”
Many of the problems he identified relate to wait times.
“From access to GPs (general practitioners) and to community and mental health services, on to accident and emergency, and then to waits not just for more routine surgery and treatment but for cancer and cardiac services, waiting time targets are being missed,” he wrote in his report.
For example, “as of June 2024, more than one million people were waiting for community services, including more than 50,000 people who had been waiting for over a year, 80% of whom are children and young people,” he wrote.
Accident and emergency care (A/E) “is in an awful state,” the report noted, “with A/E queues more than doubling from an average of just under 40 people on a typical evening in April 2009 to over 100 in April 2024. One in 10 patients are now waiting for 12 hours or more.”
“In the last 15 years, the NHS was hit by three shocks—austerity and starvation of investment, confusion caused by top-down reorganization, and then the pandemic which came with resilience at an all-time low. Two out of three of those shocks were choices made in Westminster,” said NHS surgeon and former Health Minister Lord Ara Darzi in a government press release. “It took more than a decade for the NHS to fall into disrepair so it’s going to take time to fix it. But we in the NHS have turned things around before, and I’m confident we will do it again.” (Photo copyright: Health Data Research UK.)
Delays in Other Critical Tests
Genetic test results are lagging as well. “In 2024, more than 35,000 genomic tests are being completed each month but only around 60% on time,” Darzi wrote.
He also noted that “only around 5% of eligible patients with brain cancer are able to access whole genome sequencing (WGS), which is important for treatment selection.” Just two-thirds (65.8%) get their first treatment within 62 days, and more than 30% wait more than 31 days for radical radiotherapy, according to the report.
Overall, “the UK has appreciably higher cancer mortality rates than other countries, with no progress whatsoever made in diagnosing cancer at stage one and two between 2013 and 2021,” he wrote.
Patients have also experienced delays in access to cardiovascular treatment. For example, in 2013-2014, high-risk heart attack patients waited an average of 114 minutes for intervention to unblock an artery, Darzi noted in his report. However, in 2022-2023, the average time was 146 minutes, a 28% increase.
“For the most part, once people are in the system, they receive high quality care,” he wrote. “But there are some important areas of concerns, such as maternity care, where there have been a succession of scandals and inquiries.”
Key Factors Leading to Delays
Darzi pointed to four key factors that have led to the problems.
Lack of funding. “The 2010s was the most austere decade since the NHS was founded, with spending growing at around 1% in real terms,” Darzi wrote, compared with a long-term average of 3.4%.
One result was that administrators took funds from the capital budget to cover day-to-day needs, leading to “crumbling buildings that hit productivity,” he noted.
“The backlog maintenance bill now stands at more than £11.6 billion and a lack of capital means that there are too many outdated scanners, too little automation, and parts of the NHS are yet to enter the digital era,” he wrote.
The COVID-19 pandemic. Given the preceding “decade of austerity,” NHS had fewer resources to deal with the crisis than most other high-income health systems, he wrote. As a result, NHS “delayed, cancelled, or postponed far more routine care during the pandemic than any comparable health system.” This led to “a bigger backlog than other health systems.”
Lack of patient and staff engagement. Patient satisfaction “has declined and the number of complaints has increased, while patients are less empowered to make choices about their care,” he wrote. In addition, “too many staff have become disengaged, and there are distressingly high-levels of sickness absence—as much as one working month a year for each nurse and each midwife working in the NHS.”
Management structures and systems. Darzi laid considerable blame on the UK’s Health and Social Care Act of 2012, which led to what he described as “a costly and distracting process of almost constant reorganization of the ‘headquarters’ and ‘regulatory’ functions of the NHS.”
One consequence, he wrote, is that too many clinicians have been deployed in hospitals instead of community-based care, despite years of promises by successive governments to put more emphasis on the latter.
National Health in Decline
Along with issues within the NHS, “the health of the nation has deteriorated and that impacts its performance,” Darzi wrote. “There has been a surge in multiple long-term conditions, and, particularly among children and young people, in mental health needs. Fewer children are getting the immunizations they need to protect their health, and fewer adults are participating in some of the key screening programs, such as for breast cancer.”
Darzi’s investigation included frontline visits to NHS facilities as well as focus groups with NHS staff and patients, the press release states. He also consulted an expert reference group consisting of more than 70 organizations and examined analyses from NHS England, the UK’s Department of Health and Social Care, and external groups.
It is interesting that there is no mention of anatomic pathology and medical laboratory testing services in Lord Darzi’s report. As reported in recent years by new outlets in the United Kingdom, delays in cancer diagnoses—often as long as six months—were severe enough that, in 2018, the NHS announced funding for a program to create a national digital pathology network to improve productivity of pathologists and shorten wait times for the results of cancer tests.
Clinical laboratory managers should note that this company’s new diagnostic offering involving screening embryos for specific genetic conditions is not without controversy
Is the world ready for whole genome sequencing (WGS) of preimplantation embryos to help couples undergoing in vitro fertilization (IVF) treatments know if their embryos have potential genetic health problems? Orchid Health, a clinical preimplantation genetic testing (PGT) laboratory that conducts genetic screening in San Francisco, believes the answer is yes! But the cost is high, and the process is not without controversy.
According to an article in Science, Orchid’s service—a sequencings of the whole human genome of preimplantation embryos at $2,500 per embryo tested—“will look not just for single-gene mutations that cause disorders such as cystic fibrosis, but also more extensively for medleys of common and rare gene variants known to predispose people to neurodevelopmental disorders, severe obesity, and certain psychiatric conditions such as schizophrenia.”
However, Science also noted that some genomics researchers “claim the company inappropriately uses their data to generate some of its risk estimates,” adding that the “Psychiatric Genomics Consortium (PGC), an international group of more than 800 researchers working to decode the genetic and molecular underpinnings of mental health conditions, says Orchid’s new test relies on data [PGC] produced over the past decade, and that the company has violated restrictions against the data’s use for embryo screening.”
There are some who assert that a whole genome sequence of an embryo—given today’s state of genetic technology and knowledge—could generate information that cannot be interpreted accurately in ways that help parents and doctors make informed prenatal testing decisions. At the same time, criticisms expressed by the PGC raise reasonable points.
Perhaps this is a sign of the times. Orchid Health is the latest genetic testing company that is looking to get ahead of genetic testing competitors with its diagnostics offerings. Meanwhile, knowledgeable and credible experts question the appropriateness of this testing, given the genetic knowledge that exists today.
“This is a major advance in the amount of information parents can have,” Orchid’s founder and CEO Noor Siddiqui (above) told CNBC. “The way that you can use that information is really up to you, but it gives a lot more control and confidence into a process that, for all of history, has just been totally left to chance.” Should Orchid Health’s analysis prove useful, pediatricians could order further clinical laboratory prenatal testing to confirm and diagnose potential genetic diseases for parents.

Orchid Receives World-class Support
Regardless of the pushback from some genetic researchers, Orchid has attracted several world-class geneticists and genetics investors to its board of advisors. They include:
Jacques Cohen, PhD, embryologist, co-founder and former director for genetics laboratory Reprogenetics LLC (now CooperGenomics).
Anne Wojcicki, co-founder and CEO of direct-to-consumer genetic testing company 23andMe.
and others.
The WGS test, according to Orchid, detects genetic errors in embryos that are linked to severe illnesses before a pregnancy even begins. And by sequencing 99% of an embryo’s DNA, the test can spot potential health risks that could affect a future baby.
According to its website, the PGT lab company uses the WGS data to identify both monogenic (single-gene) and polygenic (multiple-gene) diseases, including:
Orchid is not without its critics. Knowledgeable, credible experts have questioned the appropriateness of this type of genetic testing. They fear it could become a modern-day form of eugenics.
Andrew McQuillin, PhD, Professor of Molecular Psychiatry at University College London, has concerns about Orchid’s preimplantation genetic testing. He maintains that it is difficult to control how such data is used, and that even the most accurate sequencing techniques do not predict disease risk very well.
“[Polygenic risk scores are] useful in the research context, but at the individual level, they’re not actually terribly useful to predict who’s going to develop schizophrenia or not,” McQuillin told Science. “We can come up with guidance on how these things should be used. The difficulty is that official guidance like that doesn’t feature anywhere in the marketing from these companies.”
McQuillin also stated that researchers must have an extensive discussion regarding the implications of this type of embryo screening.
“We need to take a look at whether this is really something we should be doing. It’s the type of thing that, if it becomes widespread, in 40 years’ time, we will ask, ‘What on Earth have we done?’” McQuillin emphasized.
Redefining Reproduction
It takes about three weeks for couples to receive their report back from Orchid after completing the whole genome sequence of a preimplantation embryo. A board-certified genetic counselor then consults with the parents to help them understand the results.
Founder and CEO Noor Siddiqui hopes Orchid will be able to scale up its operations and introduce more automation to the testing process to the cost per embryo.
“We want to make this something that’s accessible to everyone,” she told CNBC.
“I think this has the potential to totally redefine reproduction,” she added. “I just think that’s really exciting to be able to make people more confident about one of the most important decisions of their life, and to give them a little bit more control.”
Clinical laboratories have long been involved in prenatal screening to gain insight into risk levels associated with certain genetic disorders. Even some of that testing comes with controversy and ambiguous findings. Whether Orchid Health’s PGT process delivers accurate, reliable diagnostic insights regarding preimplantation embryos remains to be seen.
Another study in the United Kingdom that also used genomic analysis to understand drug-resistant Shigella produced findings that may be useful for microbiologists and medical laboratory scientists
From the onset of an infectious disease outbreak, public health officials, microbiologists, and clinical laboratory managers find it valuable to trace the origin of the spread back to the “index case” or “patient zero”—the first documented patient in the disease epidemic. Given the decreased cost of genomic analysis and improved accuracy of gene sequencing, infectious disease researchers are finding that task easier and faster than ever.
One recent example is a genomic study conducted at University of Washington (UW) in Seattle that enabled researchers to “retrace” the origin and spread of a “multidrug-resistant Shigellosis outbreak” from 2017 to 2022. “The aim of the study was to better understand the community transmission of Shigella and spread of antimicrobial resistance in our population, and to treat these multi-drug resistant infections more effectively,” the UW scientists stated in a new release.
Shigellosis (aka, bacillary dysentery) is a highly contagious disease of the intestines that can lead to hospitalization. Symptoms include fever, stomach cramps, diarrhea, dysentery, and dehydration.
“Additional analysis of the gut pathogen and its transmission patterns helped direct approaches to testing, treatment, and public health responses,” the UW news release states.
Usually prevalent in countries with public health and sanitation limitations, the “opportunistic” Shigella pathogen is now being seen in high-income countries as well, UW reported.
“You can’t really expect an infectious disease to remain confined to a specific at-risk population. [Shigella infections are] very much an emerging threat and something where our public health tools and therapeutic tools have significant limitations,” infectious disease specialist Ferric Fang, MD (above) told CIDRAP News. Fang is a UW professor of Microbiology and Clinical Laboratory Medicine and a corresponding author of the UW study. (Photo copyright: University of Washington.)
Generally, Shigella infects children, travelers, and men who have sex with men (MSM), the CDC noted.
The UW researchers were motivated to study Shigella when they noticed an uptick in drug-resistant shigellosis cases in Seattle’s homeless population in 2020 at the beginning of the COVID-19 pandemic, Center for Infectious Disease Research and Policy News (CIDRAP News) reported.
“Especially during the pandemic, a lot of public facilities were closed that homeless people were used to using,” infectious disease specialist Ferric Fang, MD, told CIDRAP News. Fang is Professor of Microbiology and Laboratory Medicine at University of Washington and corresponding author of the UW study.
The researchers studied 171 cases of Shigella identified from 2017 to 2022 by clinical laboratories at Harborview Medical Center and UW Medical Center in Seattle. According to CIDRAP News, the UW researchers found that:
46% were men who have sex with men (MSM).
51% were people experiencing homelessness (PEH).
Fifty-six patients were admitted to the hospital, with eight to an intensive care unit.
51% of isolates were multi-drug resistant (MDR).
Whole-Genome Sequencing Reveals Origin
The UW scientists characterized the stool samples of Shigella isolates by species identification, phenotypic susceptibility testing, and whole-genome sequencing, according to their Lancet Infectious Diseases paper. The paper also noted that 143 patients received antimicrobial therapy, and 70% of them benefited from the treatment for the Shigella infection.
Whole-genome sequencing revealed that two strains of Shigella (S. flexneri and S. sonnei) appeared first in Seattle’s MSM population before infecting the PEM population.
The genomic analysis found the outbreak of drug-resistant Shigella had international links as well, according to CIDRAP News:
One S. flexneri isolate was associated with a multi-drug resistant (MDR) strain from China, and
S. sonnei isolates resembled a strain characteristic of a current outbreak of MDR Shigella in England.
“The most prevalent lineage in Seattle was probably introduced to Washington State via international travel, with subsequent domestic transmission between at-risk groups,” the researchers wrote.
“Genomic analysis elucidated not only outbreak origin, but directed optimal approaches to testing, treatment, and public health response. Rapid diagnostics combined with detailed knowledge of local epidemiology can enable high rates of appropriate empirical therapy even in multidrug-resistant infection,” they continued.
UK Shigella Study Also Uses Genomics
Another study based in the United Kingdom (UK) used genomic analysis to investigate a Shigella outbreak as well.
Motivated by a UK Health Security Agency report of an increase in drug-resistance to common strains since 2021, the UK researchers studied Shigella cases from September 2015 to June 2022.
According to a paper they published in Lancet Infectious Diseases, the UK researchers “reported an increase in cases of sexually transmitted S. flexneri harboring blaCTX-M-27 (an antibiotic-resistant gene) in England, which is known to confer resistance to third-generation cephalosporins (antibiotics),” the researchers wrote.
Their analysis of plasmids (DNA with genes having antibiotic resistance) revealed a link in two drug-resistant Shigella strains at the same time, CIDRAP News explained.
“Our study reveals a worsening outlook regarding antimicrobial-resistant Shigella strains among MSM and highlights the value of continued integration of genomic analysis into surveillance and research,” the UK-based scientists wrote.
Current challenges associated with Shigella, especially as it evades treatment, may continue to demand attention from microbiologists, clinical laboratory scientists, and infectious disease specialists. Fortunately, use of genomic analysis—due to its ongoing improvements that have lowered cost and improved accuracy—has made it possible for public health researchers to better track the origins of disease outbreak and spread.
Goal is to demonstrate how whole human genome sequencing of newborns can deliver important diagnostic findings associated with 250 genetic conditions
Clinical laboratory testing and genetics are moving closer to the delivery room than ever before. In the largest study of its kind in North America, genomic scientists plan to supplement traditional screening for inherited diseases—traditionally performed on a blood sample taken shortly after birth—with whole genome sequencing (WGS) on 100,000 newborns in New York City during their first five years of life, LifeSciencesIntelligence reported.
Conducted by genetic scientists at NewYork-Presbyterian (NYP) and Columbia University, in collaboration with genetic company GeneDx, a wholly-owned subsidiary of health intelligence company Sema4 (NASDAQ:SMFR), the genetic research study, called GUARDIAN (Genomic Uniform-screening Against Rare Diseases In All Newborns), will screen newborn babies for 250 rare diseases that are generally not tested for.
The GUARDIAN program will “drive earlier diagnosis and treatment to improve the health of the babies who participate, generate evidence to support the expansion of newborn screening through genomic sequencing, and characterize the prevalence and natural history of rare genetic conditions,” according to a Sema4 news release.
“The appetite for this is growing. The awareness of this is growing. We all see it as inevitable,” medical geneticist Robert Green, MD, at Brigham and Women’s Hospital and Harvard Medical School told USA Today. “We are grossly underutilizing the life-saving benefits of genetics and we have to get past that.” Clinical laboratory leaders understand the value of early detection of disease and subsequent early treatment.

Improving Health of Babies Through Early Detection of Disease
GUARDIAN aims to use WGS to identify conditions at birth that can affect long-term health and subsequently enhance treatment options and possibly prevent disability or death.
The 250 different diseases GUARDIAN will be screening for typically strike young children. They are mostly rare conditions that:
have an onset before five years of age,
have a greater than 90% probability of the condition developing based on the genetic result,
have effective approaches and treatments that are already available, and/or
have a well-established natural history of the condition.
“We’re entering the therapeutic era and leaving the diagnostic era,” Paul Kruszka, MD, Chief Medical Officer at GeneDx told USA Today. “This potentially has the opportunity to change the way we practice medicine, especially in rare disease.”
Some Parents Reluctant to Agree to Genetic Testing
Green and his research team first began analyzing the genetic sequences of newborns back in 2013. They believe the costs of performing infant WGS is worthwhile because it can improve lives. However, Green also recognizes that some parents are reluctant to agree to this type of genetic testing due to concerns regarding privacy and the fear of discovering their baby may have an illness.
“You’ve gone through all this pregnancy and you’re sitting there with a healthy baby (and I’m) offering you the opportunity to find out something that’s devastating and terrifying,” he told USA Today. “How fun is that?”
Green continued. “We can respect people who don’t want to know, but also respect people who do want to know. Some families will say ‘I treasure the precious ignorance.’ Others will say ‘If I could have known, I would have poured my heart and soul into clinical trials or spent more time with the child when she was healthy.’”
WGS Screening Identifies Undiagnosed Illnesses in Newborn’s Family
The scientists also found that performing WGS in newborns can detect diseases in the infants as well as unknown illnesses in the families of those babies. According to Kruszka, many parents often seek a diagnosis for a rare disease present in their children for several years. Since many common diseases develop as a result of certain combinations of genes, if illnesses are diagnosed at birth, it could extradite the treatment process, prevent complications, and provide better health outcomes for patients.
“We are relentlessly focused on accelerating the adoption and use of genomic information to impact the lives of as many people as possible, particularly newborns and children,” said Katherine Stueland, President and CEO, Sema4, in the Sema4 news release. “As the first commercial laboratory to launch a rapid whole genome sequencing offering, to address broad unmet needs for early diagnosis, participation in this study is an important step forward for healthcare and in delivering on our goal to sequence once, analyze forever.”
The study is open to all babies in New York City who are born in a health system that participates in the GUARDIAN program, regardless of their race, income, or health insurance coverage.
“The results from this study will help us understand the true impact sequencing at birth can have on newborns and their families in comparison to the current standard of care, particularly as we’ll evaluate clinical outcomes in addition to the psychosocial effect on families,” said Kruszka in the Sema4 news release.
Anything that improves the health of newborn babies is a good thing. Regardless of the cost, if DNA analysis can give newborns and their families a better chance at detecting inherited diseases early while clinical laboratory treatment could make a difference, it is worth pursuing.
Genetic testing for the health and wellbeing of beloved pets is not unlike clinical laboratory testing to develop personalized treatments for humans
Clinical laboratory professionals know that the same patients who complain about a $10 copay for their own laboratory testing will happily pay veterinarians tons of cash to test and treat their beloved pets. And as genetic testing for humans becomes commonplace, more people are seemingly willing to pay for genetic analyses of their pets as well.
In June, animal health company Zoetis, Inc. announced it had completed the acquisition of pet care genetics company Basepaws. The financial terms of the deal were not disclosed.
California-based Basepaws is a privately-held company that provides pet owners with analytics, genetic tests, and early health risk assessments for their pets through oral microbiome analysis. Founded in 2017, Basepaws was responsible for the creation of the first at-home genetic testing platform for cats.
Basepaws sells easy-to-use genetic testing kits for cats that allow pet owners and veterinarians to better understand an individual pet’s predisposition to certain illnesses and increase the likelihood of early detection and treatment of those diseases.
It’s not unlike the drive toward personalized medicine and genetic testing that is at the core of human precision medicine.
Different Breeds, Different Needs
Basepaws has a slogan: “Different breeds, different needs.” This means, according to their website, each individual cat has a unique composition of genetic traits that can relate to its needs for optimal health and wellbeing. Obviously, this would apply to all pets.
“As a pioneer in pet care genetics, the California-based Basepaws offers easy-to-use genetic screening tools for the early detection of disease risk in pets, as well as individualized breed and health reports that can identify traits, biomarkers, and potential hereditary conditions for pets. Basepaws helps pet owners and veterinarians understand an individual pet’s risk for disease and can lead to more meaningful engagements and increased likelihood of early detection and treatment of disease,” states a Zoetis press release announcing the acquisition.
“The addition of Basepaws will enhance our portfolio in the precision animal health space and inform our future pipeline of pet care innovations,” said Kristin Peck, CEO of Zoetis, in the press release. “Working together, we can continue to provide veterinarians and pet owners with more comprehensive ways to proactively manage the health, wellness, and quality of care for their animals.”
“Basepaws and Zoetis both consist of pet lovers with a passion for science, and our mission is to create better and longer lives for our pets through knowledge and data,” Anna Skaya (above), CEO of Basepaws, told ROI-N.J. “We look forward to expanding our business and the impact of our genetic products with the global scale and [research and development] experience of Zoetis, the world leader in animal health. We believe that, together, we can bring the benefits of a more proactive healthcare approach to pet parents around the world.” Genetic testing for optimum pet health is not unlike the drive for personalized clinical laboratory genetic testing for humans.

Test Results for Hundreds of Genetic Disorders and Health Markers
Basepaws currently sells three DNA test kits for felines on their webpage. The current price for an oral health test kit that identifies active signs of dental diseases is $69. Their breed and cat health DNA test kit, which provides results for over 115 known feline genetic markers, is $129. Their most comprehensive testing kit is a whole genome sequencing (WGS) kit which is currently on sale for $399.
After receiving a test kit by mail, the purchaser registers the kit online, takes a single buccal swab from their kitty’s inner cheek, and then mails the sample to Basepaws. Lab personnel then extract the cat’s DNA from the sample and perform quality checks to ensure the sample is acceptable for genetic testing. It takes four to six weeks for consumers to receive test results.
According to the company’s website, Basepaws’ WGS test provides results related to 43 genetic disorders that are represented by 65 health markers. The listing of genetic disorders contained in the Health Marker section of the Basepaws report includes data on:
Metabolic disorders,
Musculoskeletal and connective tissue disorders,
Renal disorders,
Cardiovascular disorders,
Blood disorders,
Eye disorders,
Endocrine disorders,
Skin disorders, and
Autoimmune disorders.
“The Basepaws team has done an amazing job demonstrating how genetic testing and data can improve how we care for the pets in our lives,” Abhay Nayak, Executive Vice President at Zoetis, told ROI-NJ. “With the addition of Basepaws, Zoetis will continue to strengthen our portfolio of products for precision animal health, across genetics, diagnostics, and data analytics for pets and livestock. We are also excited by how Basepaws’ feline genomic and microbiome database will help enhance our [research and development] capabilities and inform the future of our pet care pipeline.”
Zoetis, based in Parsippany, N.J., manufactures vaccines, medicines, clinical laboratory diagnostics, and other technologies for the benefit of companion pets and livestock. The Fortune 500 company generated $7.8 billion in revenue in 2021, according to its website.
The article also stated that the global animal genetic testing market was valued at $990 million in 2020 and is only expected to rise.
Thus, spending money keeping our pets healthy is not only a typical element of Americans’ lives, but also a mega-billion-dollar industry. With at-home genetic testing for humans increasing in popularity, it’s likely testing for animals will follow that trend as well.
In the future, some clinical laboratory organizations may want to consider assessing the animal DNA testing market for its potential to be a useful source of new revenue, especially because potential customers will pay cash when they order genetic tests for their dogs and cats.
