New guidelines also advise people to limit their vitamin D supplementation to recommended daily doses
Clinical laboratories may eventually receive fewer doctors’ orders for vitamin D testing thanks to new guidelines released by the Endocrine Society. The new Clinical Practice Guideline advises against “unnecessary testing for vitamin D levels.” It also urges healthy people, and those 75-years of age or younger, to avoid taking the vitamin at levels above the daily recommended amounts, according to a news release.
Even though the Endocrine Society does recommend vitamin D supplements for certain groups, it advises individuals to hold off on routine testing. That’s because there appears to be uncertainty among ordering clinicians about what to do for patients based on their vitamin D test results.
“When clinicians measure vitamin D, they’re forced to decide what to do about it. That’s where questions about the levels come in. And that’s a big problem. So, what this panel is saying is ‘Don’t screen,’” Clifford Rosen, MD, Director of Clinical and Translational Research and Senior Scientist, Maine Medical Center Research Institute at the University of Maine, told Medscape Medical News.
“We have no data that there’s anything about screening that allows us to improve quality of life. Screening is probably not worthwhile in any age group,” he added.
“This guideline refers to people who are otherwise healthy, and there’s no clear indication for vitamin D, such as people with already established osteoporosis. This guideline is not relevant to them,” the author of the Endocrine Society guideline, Anastassios G. Pittas, MD (above), Professor of Medicine at Tufts University School of Medicine in Boston, told Medscape Medical News.

Vitamin D Screening Not Recommended for Certain Groups
The Endocrine Society’s new clinical guidelines advise healthy adults under 75 years of age to refrain from taking vitamin D supplements that exceed US Institute of Medicine—now the National Academy of Medicine (NAM)—recommendations.
Additionally, these updated guidelines:
Recommend vitamin D supplements at levels above NAM recommendations to help lower risks faced by children 18 years and younger, adults 75 and older, pregnant women, and people with prediabetes.
Suggest daily, lower-dose vitamin D (instead of non-daily, higher-dose of the vitamin) for people 50 years and older who have “indications for vitamin D supplementation or treatment.”
Advise “against routine testing for 25-hydroxyvitamin D [aka, calcifediol] levels” in all the above groups “since outcome-specific benefits based on these levels have not been identified. This includes 25-hyrdoxyvitamin D screening in people with dark complexion or obesity.”
One exception to the guideline applies to people with already established osteoporosis, according to the guideline’s author endocrinologist Anastassios G. Pittas, MD, Chief of Endocrinology, Diabetes and Metabolism; Co-Director, Tuft’s Diabetes and Lipid Center; and Professor of Medicine at Tufts University School of Medicine in Boston.
Vitamin D’s Link to Disease Studied
During a panel discussion at the Endocrine Society’s annual meeting, members acknowledged that many studies have shown relationships between serum concentrations of 25-hydroxy vitamin D (25(OH)D) and physical disorders including those of musculoskeletal, metabolic, and cardiovascular systems. Still, they questioned the link of vitamin D supplementation and testing with disease prevention.
“There is paucity of data regarding definition of optimal levels and optimal intake of vitamin D for preventing specific diseases. … What we really need are large-scale clinical trials and biomarkers so we can predict disease outcome before it happens,” said Panel Chair Marie Demay, MD, Endocrinologist, Massachusetts General Hospital, and Professor of Medicine, Harvard Medical School, Boston, Medscape Medical News reported.
Meanwhile, in their Journal of Clinical Endocrinology and Metabolism paper, the researchers note that use of supplements (1,000 IU or more per day) increased from 0.3% to 18.2%, according to the National Health and Nutrition Examination Survey (NHANES) conducted by the National Center for Health Statistics (NCHS), CDC, for the years 1999-2000 and 2013-2014.
“The use of 25(OH)D testing in clinical practice has also been increasing; however, the cost effectiveness of widespread testing has been questioned, especially given the uncertainty surrounding the optimal level of 25(OH)D required to prevent disease,” the authors wrote.
“Thus, the panel suggests against routine 25(OH)D testing in all populations considered,” the researchers stated at the Endocrine Society annual meeting.
Other Groups Weigh-in on Vitamin D Testing
Pathologists and medical laboratory leaders may recall the explosion in vitamin D testing starting about 20 years ago. Vitamin D testing reimbursed by Medicare Part B “increased 83-fold” during the years 2000 to 2010, according to data cited in an analysis by the American Academy of Family Physicians (AAFP).
Also, the US Preventive Services Task Force (USPSTF) said in a statement that there is not enough information to “recommend for or against” testing for vitamin D deficiency.
“No organization recommends population-based screening for vitamin D deficiency, and the American Society for Clinical Pathology recommends against it,” the USPSTF noted.
Clinical Laboratories Can Get the Word Out
The vitamin D debate has been going on for a while. And the latest guidance from the Endocrine Society may cause physicians and patients to stop ordering vitamin D tests as part of annual physicals or in routine screenings.
Medical laboratories can provide value by ensuring physicians and patients have the latest information about vitamin D test orders, reports, and interpretation.
Growth of the middleman company is a sign of increased credibility and acceptance among its client organizations
There’s a new category of player in the clinical laboratory testing industry. It is the “middleman” company. One high-profile example of a middleman company in diagnostics is the company ixlayer of San Francisco, which has a novel plan for growth.
The software developer provides cloud-based diagnostic testing platforms to retailers, health plans, and biopharma companies. Medical laboratory tests are not processed by ixlayer, however, but are instead sent to independent CLIA-certified clinical labs for completion and results reporting.
Thus, ixlayer acts as a third-party “middleman” in the lab testing chain.
Ixlayer recently debuted as number 1,418 on the 2023 Inc. 5000 list of fastest-growing private companies in the US, according to a company news release. Might this signal a dynamic and expanding clinical laboratory middleman sector?
There are a number of other established middleman companies doing this on the web as well, including:
Produced by Inc. Business Media, the Inc. 5000 list is based on data analysis of the fastest growing private businesses in the US. Ixlayer reportedly grew its 2023 revenue 100% year-over-year.
“To be selected for the Inc. 5000 list is an honor that validates the value we deliver while enabling greater access to care for all,” said Pouria Sanae (above), co-founder and CEO of ixlayer. “We’ve developed a platform that powers millions of diagnostic tests each year and serves as the backbone of thousands of health testing programs for trusted health brands, healthcare delivery organizations, payers, and life sciences companies. I’m excited about the future as we redefine and simplify the diagnostic laboratory testing ecosystem.” (Photo copyright: ixlayer.)
Ixlayer Works with Retailers, Insurers, Biopharma, and Clinical Labs
Ixlayer “facilitates” tests by working with industry partners and clinical laboratories, Managed Healthcare Executive explained.
One such relationship is with retailer CVS, Fierce Healthcare reported. Ixlayer provides the cloud-based diagnostics platform, at-home sample collection kits, and coordination of testing services for some of the pharmacy company’s at-home testing products. They include:
“With nearly 70% of medical decisions dependent on lab testing, regular diagnostic testing is a cornerstone of improving health and wellness,” Pouria Sanae, co-founder and CEO of ixlayer, told Drug Store News. “At-home testing enables people to proactively take control of their health, on their own schedule, in the privacy of their own home and on a regular basis. Our mission of creating a healthier world through more accessible, affordable, and easy health testing requires systemic changes and buy-in from key stakeholders and partners.”
Ixlayer directs specimens to independent labs that perform the tests and report results to consumers via an online portal.
“Founded in 2018, ixlayer initially focused on remote lab testing for Alzheimer’s disease patients. The company now offers thousands of white-labeled, at-home, and onsite health tests ranging from women’s wellness to sexually transmitted diseases and chronic condition management,” the news release notes.
“We’re thinking of it more from the perspective of: How do we infiltrate this infrastructure into our whole healthcare ecosystem? How do we let traditional providers run their programs the way they want to?” Alecia Pritchett, ixlayer Chief Growth Officer, told Managed Healthcare Executive.
Ixlayer “is not a lab,” Managed Healthcare Executive explained. “It describes itself as a platform. Instead of performing its own lab tests, it connects providers and retailers to accredited laboratory partners. Instead of sending out its own team of phlebotomists to collect blood samples, the company coordinates with mobile phlebotomy firms.”
“This comprehensive data visualization solution provides a more insightful analysis of testing performance data, empowering health plans, retailers, and biopharma organizations to monitor and manage progress in real-time effectively. With this actionable intelligence, decision-makers can focus on addressing gaps in care, accelerating access to critical drug studies, and promoting greater health equity to improve clinical and quality outcomes and economics across the healthcare ecosystem,” said David Yu, Chief Product Officer at ixlayer, in a news release.
Any Lab Test Now Also Makes Inc.’s 5000 List
Also making the 2023 Inc. 5000 list is Any Lab Test Now, an Alpharetta, Ga.-headquartered laboratory franchise that was founded in 2007. Any Lab Test Now is another form of middleman company which bills itself as the nation’s first direct access lab testing service with 200 locations. This is Any Lab Test Now’s second consecutive year on the list, according to a news release.
Unlike ixlayer, Any Lab Test Now’s business model features independently owned and operated locations around the US. Customers go online to choose a testing location, pay for tests, and schedule an appointment. Tests include:
Allied Market Research reported that the global at-home testing market is expected to grow by about 10.5% annually from 2022 to 2031, when it will reach $45.5 billion.
Another middleman company offering at-home tests is Everlywell of Austin, Texas. Other middleman companies that enable consumers to order tests online and then visit a local clinical laboratory for specimen collection include Testing.com and Walk-In-Lab.com.
Ever since the COVID-19 pandemic, demand for at-home sample collection testing has grown steadily. Dark Daily has covered this in numerous ebriefs. That middleman companies are showing up on the Inc. 5000 list of fastest growing companies indicates that the middleman sector of the clinical laboratory testing industry is growing as well.
New USPSTF guidelines suggest reducing the volume of Vitamin D deficiency testing in the general population, which could reduce revenue for clinical laboratories
From 2005 to 2011, the volume of clinical laboratory tests for Vitamin D soared nationally as more doctors tested more patients for Vitamin D deficiency. This became a major source of revenue growth for many clinical laboratories performing those tests. But at least a portion of lab revenue associated with Vitamin D testing may be in jeopardy.
In a recommendation statement published in JAMA Network, titled, “Screening for Vitamin D Deficiency in Adults,” the United States Preventive Services Task Force (USPSTF)—following up on its 2014 recommendations—stated “that the current evidence is insufficient to assess the balance of benefits and harms of screening for Vitamin D deficiency in asymptomatic adults.”
The USPSTF’s new recommendations concerning Vitamin D testing came after the federal task force performed an extensive review of the benefits and potential harm of screening for Vitamin D deficiencies in non-pregnant adults who displayed no symptoms of a deficiency. Symptoms of a Vitamin D deficiency include fatigue and tiredness, bone and back pain, depression, impaired would healing, bone loss, hair loss, and muscle pain.
After completing its research, the USPSTF concluded “the overall evidence on the benefits of screening for Vitamin D deficiency is lacking. Therefore, the balance of benefits and harms of screening for Vitamin D deficiency in asymptomatic adults cannot be determined.”
Are USPSTF Conclusions Contrary to Current Deficiency Testing Practices?
“Among asymptomatic, community-dwelling populations with low Vitamin D levels, the evidence suggests that treatment with Vitamin D has no effect on mortality or the incidence of fractures, falls, depression, diabetes, cardiovascular disease, cancer, or adverse events,” the JAMA Network article states.
Other studies have linked low Vitamin D levels with some health conditions and risks, however, the USPSTF review found no studies that directly evaluated any perks associated with Vitamin D screening in otherwise healthy individuals.
Everyday Health listed 10 illnesses linked to low Vitamin D deficiency. They include:
“We see a lot of associations between Vitamin D deficiency and poor health outcomes,” Mary Byrn, PhD, RN, an associate professor at Loyola University in Chicago who studies Vitamin D, told Everyday Health. “Although these are relationships and we are unable to conclude cause and effect, taking Vitamin D supplements or exposing yourself to the sun in a safe manner to increase Vitamin D naturally are easy ways to improve your health and try to reduce your risk of multiple diseases,” she said.

Can Vitamin D Supplementation Be Harmful?
The USPSTF study also stated that Vitamin D supplementation appears to be safe and that toxicity from too much Vitamin D would be rare. One of the USPSTF’s key concerns of screening for Vitamin D in asymptomatic individuals was the potential for misclassification and inaccurate diagnoses.
The study also revealed that more research is needed to determine what serum levels are optimal when diagnosing a Vitamin D deficiency, and whether those levels vary by subgroups, such as race, ethnicity, or gender.
The JAMA Network article states that “the evidence is inconclusive about the effect of treatment on physical functioning and infection.”
The amount of Vitamin D individuals need each day depends upon their age. The National Institutes of Health (NIH) recommends that adults between the ages of 19 and 70 get 15 micrograms or 600 International Units (IU) of Vitamin D daily.
According to an NIH fact sheet, people can receive Vitamin D through sun exposure, supplements, and some food, such as fatty fish, mushrooms, beef liver, cheese, and egg yolks, plus foods that are fortified with Vitamin D, such as some milk products and breakfast cereals.
Vitamin D and COVID-19
It has been widely reported that approximately 42% of Americans are Vitamin D deficient. And Vitamin D deficiency has been linked to an increased risk of contracting the SARS-CoV-2 coronavirus and how well patients recover after COVID-19 treatment.
A study published in the Journal of Clinical Endocrinology and Metabolism that examined 216 COVID-19 hospitalized patients in Spain found that over 80% of those individuals were deficient in Vitamin D. The study also found that COVID-19 patients who had lower Vitamin D levels also had a higher number of inflammatory markers that have been associated with poorer COVID-19 outcomes. The results of this study were in March.
For several decades, experts have recommended avoiding sun exposure and using sunscreen to avoid skin cancers. This may have caused people to get less Vitamin D from sun exposure. It may also have contributed to an increase in the number of Vitamin D deficiencies and increased COVID-19 infections.
Pathologists and clinical laboratory managers should keep in mind that the USPSTF recommended less testing for Vitamin D deficiencies in asymptomatic individuals. This proposal may affect test volume in clinical laboratories, as Vitamin D testing has been a common and lucrative assay for many years.
If direct-to-consumer testing continues to attract healthcare consumers and financial investors, medical laboratories could have a new source of revenue
Many have tried but few have found the right formula to
offer medical laboratory tests directly to consumers. Direct-to-consumer lab
testing as a robust business model has been an elusive goal. But now one
entrepreneur wants to crack this market and just attracted $50 million in
venture capital to fund her idea!
Outsiders often establish industries. This was the case when Jeff Bezos created Amazon in 1994. The online retailer transformed the way books were sold and, subsequently, established a massive new retail market.
Along the same lines, Julia Taylor Cheek, Founder and CEO of EverlyWell, a well-financed digital health company based in Austin—hopes to build a similarly disruptive business in the clinical laboratory industry.
Cheek is increasing her company’s outreach to consumers by
putting some of the company’s direct-to-consumer (DTC) medical tests on store
shelves at CVS and Target.
A former consultant and Harvard Business School graduate, Cheek raised $50 million in financing to expand EverlyWell’s digital platform. According to a news release, “Just two full years into operation, EverlyWell is reporting 300% year-over-year customer growth and a world-class consumer Net Promoter Score (NPS).”
“I think it’s a representation of sexism in our space. There are 15 other companies that have popped up in blood testing and you don’t hear anyone comparing Theranos to those male-founded startups,” she told Inc.
However, Dark Daily believes Cheek may be missing one
basis for the comparison with Elizabeth Holmes. Holmes intended for Theranos to
serve consumers with lab testing, and let consumers order and purchase their
own medical laboratory tests. Cheek is talking about the same primary business
strategy of letting consumers purchase their own lab tests.
Armed with this additional financing from investors, EverlyWell intends to expand services and develop new partnerships with retail pharmacy chain CVS Health (NYSE:CVS) and for-profit insurance company Humana (NYSE:HUM).
The news release notes, “The company has also expanded its
product line to offer 35 panels, including first-to-market tests in fertility,
vitamins, peri- and post-menopause, and high-risk HPV. In addition, EverlyWell
has launched an end-to-end care model for consumers, now offering an
independent physician consult and prescription, if appropriate, for select STDs
and Lyme Disease testing. All of this is included in an upfront price before
purchase.”
EverlyWell Intent on
Bringing Medical Laboratory Tests to Retail
Earlier this year, EverlyWell made nine lab tests available in more than 1,600 Target store locations, MedCity News reported. This may suggest that retailers are intrigued with direct-to-consumer lab testing.
“We didn’t create new tests or technologies. Instead, we’ve built technology that empowers people to get tests more easily. Our medical director works with the labs to create panels that are already validated and clinically relevant and understandable for consumers,” Julia Taylor Cheek (above), Founder and CEO of EverlyWell told Forbes. (Photo copyright: Arnold Wells/Austin Business Journal.)
Cheek reportedly established EverlyWell after becoming
disenchanted with medical laboratory tests that she felt were not well
explained and too costly under high-deductible health plans.
Just two years on, EverlyWell reports “hundreds of thousands of customers and tens of millions in sales.” The company plans to add additional staff on top of its existing 70 employees in anticipation of the new funding, Austin Business Journal reports.
“We are building a consumer brand, which means we have to be where people shop. We need to be in places like CVS and Target to really allow for broader distribution and name recognition,” Cheek told the Austin American-Statesman.
What Draws People to EverlyWell?
EverlyWell offers home health test kits, priced from $49 to
$400 that people can order without a doctor’s prescription and pay for online. Users
take their samples (saliva, urine, or a pinprick of blood) with provided
lancets and cotton swabs, MedCity News
reported.
EverlyWell’s top selling tests are:
Food sensitivity-$159;
Thyroid function-$159;
Metabolism-$89; and
Vitamin D deficiency-$99.
EverlyWell says it is “first” in direct-to-consumer tests
for:
EverlyWell Test kits come with registration information, instructions, collection tools;
Biological samples are sent by consumers to CLIA (Clinical Laboratory Improvement Amendments)-certified labs that partner with EverlyWell;
Results are generally completed within 10 days depending on type of test and business volume;
A physician reviews the test results;
Reports on test results are electronically accessible through smartphone apps and online web dashboards.
“Lab testing is arguably one of the most important steps in preventing and managing illness but has been largely ignored by digital health companies. EverlyWell is successfully navigating an entrenched industry to offer consumers an opportunity to take charge of their own health,” said Eric Kim, Managing Partner at Goodwater Capital (which led the financing), in the news release.
“We’re building the definitive technology-enabled healthcare platform that consumers deserve and have already come to expect in other areas of their lives,” Cheek told VentureBeat. “As high-deductible plans become the norm, consumers are becoming discerning buyers who look for seamless, digitally enabled experiences.”
Learning from
EverlyWell
Of course, pathologists and medical laboratory professionals
will watch to see if EverlyWell can sustain its rapid rise in popularity with
healthcare consumers. In particular, those consumers who prefer DTC testing
over traditional clinical laboratory visits and who may be on high-deductible
health plans.
The DTC test market represents an opportunity that most
clinical laboratories have yet to take seriously. There are many reasons why
medical lab managers and pathologists would be taking a “wait and see”
attitude. Meanwhile, EverlyWell has $50 million of investors’ money to use to
demonstrate the financial viability of its strategy to encourage consumers to purchase
their own clinical laboratory tests—and even collect their own specimens at
home!
Company says it will offer five diagnostic tests that are useful to the public and some of these tests are among the highest volume tests performed by clinical labs
Heading to market is another device that works with a smartphone to provide consumers with a way to perform five popular medical laboratory tests. The product was developed by Cue, Inc., which describes itself as an entrepreneurial mobile diagnostics developer.
Cue is an at-home lab test device targeted at consumers. It will be priced at about $300, noted a report published by MobiHealthNews.
“We’re very interested in putting the power of the lab into the consumer’s hands in this new way,” said Clint Sever, Cue Cofounder and Chief Product Officer. However, pending Food and Drug Administration (FDA) clearance, Cue’s device is being presold under an “investigational exception” for $199, with promise of delivery in spring 2015.
Cue Allows Consumers to Perform Five Routine Lab Tests at Home
Initially, Cue will perform tests for influenza; testosterone; vitamin D; C-reactive protein (a marker for inflammation); and luteinizing hormone (an indicator of a women’s fertility) But that is just for starters.
According to Ayub Khattak, Cue Cofounder and CEO, the company plans to add more medical lab tests in the future. “The large majority of tests you do in the [clinical] lab today, we want to give you access to in your home,” he declared.

In its blog about Cue, IEE Spectrum noted that the first five clinical laboratory tests the company designed to run on its device were selected because these are the most common tests run by labs and, therefore, are the most useful to the public. Sever and Khattak observed in the MobiHealthNews story that all of these tests—except the influenza test—are used in monitoring a patient’s condition and are done regularly.
Athletes and older men, for instance, want to keep tabs on their testosterone levels. People are interested in Vitamin D because it affects mood. Clinical laboratories perform 70-million Vitamin D yearly, according to Khattak. Inflammation is both a predictor of heart disease and a counter indicator for intense workouts, so if the tests indicated elevated C-reactive protein, a person may want to back off from exercise for a little while, he added. The test for luteinizing hormone tells a woman when she is likely to conceive.
The influenza test, on the other hand, allows parents or other caretakers to check for flu at home, similar to taking a child’s temperature. Sever emphasized that the flu test isn’t meant to replace a doctor visit. “It just gives you more information so you can have an informed conversation with your doctor,” he said.
How the Cue Device Works
The Cue device is about the size of a Rubik’s cube. The test cartridges are about the size of a matchbox. Each cartridge uses blood, saliva, or mucus samples to conduct home lab tests. Each cartridge contains microfluidic channels and the necessary reagents for the test to be performed.
When the cartridge is inserted, Cue prompts the user to collect a sample with the sample wand that is included with the device, explained the IEE Spectrum blog. The testosterone test requires a saliva specimen. The flu test uses a nasal swab, and the other tests require a drop of blood as the specimen.
Once the sample wand is inserted into the cartridge, the reagents combine with the sample inside the cartridge. A sensor then looks for the target molecule, such as testosterone or Vitamin D, and detects the quantity or level. Cue sends this information via Bluetooth to the user’s iPhone or Android smartphone. The smartphone app allows the user to track results over time, and offers suggestions for improving health status. For example, Sever said Cue might recommend specific foods or exercise to boost low testosterone level.
Can Cue Produce More Accurate Tests Than Clinical Laboratories?
Khattak can’t make claims about the accuracy of Cue’s technology because it hasn’t yet been cleared by the FDA, noted the MobiHealthNews story. But the devices inventors believe that Cue tests have the potential to be more accurate than those performed in clinical laboratories, because the human error factor is eliminated.
“What we’ve done is we simplified and automated the whole process,” explained Khattak. “So whereas a lab technician might have 10 steps and they might do 10 of them quite well, those little errors in each of the steps add up. And human error is the largest cause of variation and deviation from standard reproducible results… With us, it is one step. You add the sample, and then you get your results.”
Cue, a modular, Rubik-cube-sized device, uses simple microfluidic laboratory technology to perform five different medical laboratory tests that people routinely have done, including testosterone and vitamin D levels, inflammation, fertility and influenza. The device is being presold under an investigational exception to consumers for $199, with promise of delivery in spring 2015. Once approved by the FDA, the price will be $300. (Photo copyright Cue)
Investors are Successful Tech Entrepreneurs and Diagnostics Experts
Clinical laboratory managers might find it interesting that Cue investors are successful entrepreneurs with expertise in both diagnostics and digital technologies. The investor group includes two University of California, Los Angeles (UCLA) professors, as well as an anonymous private investor, noted MobiHealthNews.
The other founder is Patrick Soon-Shiong, M.D., a former UCLA Medical Professor, who currently serves on the advisory board of UCLA Engineering’s Institute for Technology Advancement. Known as “LA’s billionaire doctor,” Soon-Shiong, a surgeon-turned-entrepreneur, is co-inventor on more than 40 U.S. and foreign patents and has sold two successful businesses for $8.5 billion.
Last year, Soon-Shiong launched Los Angeles-based Nantworks, LLC, a company that aims to revolutionize medicine by adding “Big Data” to patient care. Soon-Shiong also serves as Providence Health & Services’ Director for Cancer Services and Bioinformatics.
Will Consumers Pay for a Device that Does Medical Lab Tests at Home?
Will consumers be willing to pay $199 for a medical laboratory testing device that hooks up to their smartphone or tablet PC? The founders of Cue will find out next year, assuming that FDA clearance is forthcoming and the device reaches the market. Also, will Cue perform medical lab tests with accuracy that is comparable with that of the nation’s best clinical laboratories? There are many pathologists and lab scientists who will be prepared to challenge that statement.
