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.
Even US military clinical laboratories strive to cut costs, protect quality, and improve outcomes
Defense Health Agency (DHA), a part of the federal Department of Defense (DOD), recently launched a plan to consolidate healthcare facilities within certain geographical regions and to unify and integrate the military’s clinical laboratory operations in those areas. The goal is to streamline efficiencies and lower costs while maintaining quality lab testing services.
The DOD operates a nationwide network of medical treatment facilities (MTFs) that include state-of-the-art clinical and anatomic pathology laboratories serving military personnel and their families. These military labs face the same issues of cost, efficiency, and outcomes as do civilian clinical laboratories throughout the United States.
To address those challenges and bring together clinical laboratory services in specific regions, the DHA established the Tidewater Market in April of 2021 to serve select US Air Force, Army, and Navy MTFs in the Washington DC metro area, central North Carolina, Jacksonville, and coastal Mississippi.
Tidewater is the fifth Military Health System (MHS) market created to manage MTFs as they transition into the DHA.
Health.mil—a website maintained by the MHS as an informational resource for those it serves—describes the MHS as “one of America’s largest and most complex healthcare institutions, and the world’s preeminent military healthcare delivery operation.
“Our MHS saves lives on the battlefield, combats infectious disease around the world, and is responsible for providing health services through both direct care [at military hospitals and clinics known as ‘military treatment facilities’] and private sector care to approximately 9.6 million beneficiaries, composed of uniformed service members, military retirees, and family members,” Health.mil notes.
With 9.6 million beneficiaries, MHS is one of the largest healthcare service organizations operating in the United States.
“The establishment of this market provides a true opportunity to optimize healthcare for our beneficiaries by focusing on outcomes and access across the Tidewater market,” said Navy Rear Admiral Darin Via, MD, Tidewater market manager, in an MHS/DHA news release. “It also allows us to work towards standardization of processes, creating an easier environment for our patients to navigate within.” (Photo copyright: US Navy.)
Finding Efficiencies, Optimizing Clinical Laboratory Processes and Services
In an article outlining the Tidewater Market clinical laboratory initiative, Health.mil noted that “A market is a group of MTFs in one geographic area working together with its TRICARE partners, Veterans Affairs hospitals, other federal healthcare organizations, private sector teaching hospitals and medical universities, as well as other healthcare partners. Markets operate as a system to support the sharing of patients, staff, budget, and other functions across facilities to improve readiness and the delivery and coordination of health services.”
The Tidewater Market provides integrated, affordable, high-quality healthcare services to active-duty service members, military retirees, reservists and national guardsmen, and their families. The market currently serves more than 390,000 beneficiaries.
In 2022, the Tidewater Market Laboratory/Pathology Integration Working Group was created to optimize services while reducing costs within the market. The group was created by US Navy Captain Stacie Milavec, who has more than 23 years of experience in military medicine.
“One of DHA’s goals with setting up a market structure is to find efficiencies and optimize and standardize processes and services wherever possible,” Milavec said in an MHS/DHA news release. “We’ve been able to do exactly that by collaborating within our working group.”
Resource Sharing between Military Clinical Laboratories
The MTFs that are geographically close to each other helped expedite turnaround times for testing results. By working together, they saved the Tidewater Market an estimated $80,000 during fiscal year 2022.
One of the methods they used to streamline testing and lower costs was to allow resource sharing between facilities within the market. For example, the full-service clinical laboratory located at the Naval Medical Center Portsmouth (NMCP) began performing head and neck pathology cases, breast biopsies, and PAP testing for some of the other facilities within the Tidewater Market. These services were previously performed by other means and in some cases were sent to commercially-contracted clinical laboratories for analysis at a high cost.
The NMCP also took on Human Papilloma Virus (HPV) testing for all MTFs within the market.
In February of 2023, NMCP began taking on additional clinical chemistry tests from the 633rd Medical Group at Joint Base Langley-Eustis located in Hampton, Virginia. Prior to that collaboration, those tests were sent out to contracted labs off-base for analysis.
“[Through collaboration between the MTFs] we’ve been able to successfully transition civilian marketplace send-out testing back into the military market by utilizing market resources,” said pathologist US Air Force Captain Dianna Chormanski, MD, Laboratory Medical Director with the 633rd Medical Group at Joint Base Langley-Eustis, in the press release. “I’m a big fan of cooperation and working together, and that’s what a market should be.”
The DHA established the market-based structure as part of the National Defense Authorization Act for Fiscal Year 2017. It’s an example of regional laboratory consolidation within one region of the US where a common effort brought together clinical laboratories operating on military bases of different services. The military’s goal was a unified, integrated medical laboratory operation that could deliver targeted cost savings while maintaining quality lab testing services. It appears to be successful.
But even though the College of American Pathologists (CAP) and nine other organizations signed a December 12 stakeholder letter to leaders of key House and Senate committees urging passage of legislation that would enable some regulation of LDTs, the VALID Act was ultimately omitted from the year-end omnibus spending bill (H.R. 2617).
That may be due to pressure from organizations representing clinical laboratories and pathologists which lobbied hard against the bill.
Responding to criticism of its stance on FDA oversight of LDTs, in a May 2022 open letter posted on the organization’s website, anatomic pathologist and CAP president Emily Volk, MD, said “we at the CAP have an honest difference of opinion with some other respected laboratory organizations. … We believe the VALID Act is the only viable piece of legislation addressing the LDT issue. … the VALID Act contains many provisions that are similar to policy the CAP has advocated for regarding the regulation of laboratory tests since 2009. Importantly, the current version includes explicit protections for pathologists and our ability to practice medicine without infringement from the Food and Drug Administration (FDA).” (Photo copyright: College of American Pathologists.)
Organizations on Both Sides Brought Pressure to Bear on Legislators
The AAMC and AMP were especially influential, Bucshon told ProPublica. In addition to spending hefty sums on lobbying, AMP urged its members to contact legislators directly and provided talking points, ProPublica reported.
“The academic medical centers and big medical centers are in every state,” Bucshon said. As major employers in many locales, they have “a pretty big voice,” he added.
Discussing CAP’s reasoning behind its support of the VALID Act in a May 26 open letter and podcast, CAP president Emily Volk, MD, said the Valid Act “creates a risk-based system of oversight utilizing three tiers—low, moderate and high risk—in order to target the attention of the FDA oversight.”
While acknowledging that it had room for improvement, she lauded the bill’s three-tier risk-based system, in which tests deemed to have the greatest risks would receive the highest level of scrutiny.
She also noted that the bill exempts existing LDTs from an FDA premarket review “unless there is a safety concern for patients.” It would also exempt “low-volume tests, modified tests, manual interpretation tests, and humanitarian tests,” she wrote.
In addition, the bill would “direct the FDA not to create regulations that are duplicative of regulation under CLIA,” she noted, and “would require the FDA to conduct public hearings on LDT oversight.”
Pros and Cons of the VALID Act
One concern raised by opponents relates to how the VALID Act addressed user fees paid by clinical laboratories to fund FDA compliance activities. But Volk wrote that any specific fees “would need to be approved by Congress in a future FDA user fee authorization bill after years of public input.”
During the May 2022 podcast, Volk also cast CAP’s support as a matter of recognizing political realities.
“We understand that support for FDA oversight of laboratory-developed tests or IVCTs is present on both sides of the aisle and in both houses of Congress,” she said. “In fact, it enjoys wide support among very influential patient advocacy groups.” These groups “are very sophisticated in their understanding of the issues with laboratory-developed tests, and they do have the ear of Congress. There are many in the laboratory community that believe the VALID Act goes too far, but I can tell you that many of these patient groups don’t believe it goes far enough and are actively pushing for even more restrictive paradigms.”
Also urging passage of the bill were former FDA commissioners Scott Gottlieb, MD, and Mark B. McClellan, MD, PhD. In a Dec. 5 opinion piece for STAT, they noted that “diagnostic technologies have undergone considerable advances in recent decades, owing to innovation in fields like genomics, proteomics, and data science.” However, they wrote, laws governing FDA oversight “have not kept pace,” placing the agency in a position of regulating tests based on where they are made—in a medical laboratory or by a manufacturer—instead of their “distinctive complexity or potential risks.”
In their May 22 letter, opponents of the legislation outlined broad areas of concern. They contended that it would create “an onerous and complex system that would radically alter the way that laboratory testing is regulated to the detriment of patient care.” And even though existing tests would be largely exempted from oversight, “the utility of these tests would diminish over time as the VALID Act puts overly restrictive constraints on how they can be modified.”
CLIA Regulation of LDTs also Under Scrutiny
The provision to avoid duplication with the Clinical Laboratory Improvement Amendments (CLIA) program—which currently has some regulatory oversight of LDTs and IVCTs—is “insufficient,” opponents added, “especially when other aspects of the legislation call for requirements and activities that lead to duplicative and unnecessary regulatory burden.”
Opponents to the VALID Act also argued that the definitions of high-, medium-, and low-risk test categories lacked clarity, stating that “the newly created definition of moderate risk appears to overlap with the definition of high risk.”
The opponents also took issue with the degree of discretion that the bill grants to the US Secretary of Health and Human Services. This will create “an unpredictable regulatory process and ambiguities in the significance of the policy,” they wrote, while urging the Senate committee to “narrow the discretion so that stakeholders may better evaluate and understand the implications of this legislation.”
Decades ago, clinical laboratory researchers were allowed to develop assays in tandem with clinicians that were intended to provide accurate diagnoses, earlier detection of disease, and help guide selection of therapies. Since the 1990s, however, an industry of investor-funded laboratory companies have brought proprietary LDTs to the national market. Many recognize that this falls outside the government’s original intent for encouragement of laboratory-developed tests to begin with.
Though burnout due to COVID-19 pandemic plays a role, the future is bright for pathology assistants
Anatomic pathology laboratories are expanding the role of Pathologist Assistants (PathAs) beyond the traditional duties. What does that mean for the future of this critical position? In an article she penned for the College of American Pathologists (CAP), certified pathologists’ assistant Heather Gaburo, MHS, PA(ASCP)cm, explains how PathA responsibilities are evolving to meet the needs of today’s surgical pathology suite and anatomic pathology service.
The PNPL in Woodbridge, Connecticut, funded the study and worked with various pathology laboratories to gather the information presented.
In her paper published in the Archives of Pathology and Laboratory Medicine, certified pathologists’ assistant Heather Gaburo (above), wrote “PathAs can fill a wide variety of nontraditional roles in hospital-based and private practice laboratory settings. In the current state of pathology, PathAs are underused in these roles.” (Photo copyright: American Association of Pathologists’ Assistants.)
Traditional Duties of PathAs
The job of the PathA was developed in the 1970s to fill a gap in the pathology workforce. Traditional duties for PathAs include, but are not limited to, tasks such as:
Macroscopic examination (grossing process) and dissection of surgical specimens,
Assisting with intraoperative frozen sections and autopsies.
However, this role is expanding. According Gaburo, the 2021 AAPA membership survey showed that PathAs duties have grown to include tasks such as:
Why have the duties of PathAs broadened so much? According to Gaburo, the COVID-19 pandemic had much to do with it.
COVID-19 Pandemic Leads to New Duties/Burnout for PathAs
“The pandemic increased public awareness of the clinical laboratory by highlighting essential clinical workers with frequent spotlights on COVID-19 testing and staffing shortages, as well as understaffing in the anatomic space,” Gaburo said in an exclusive interview with Dark Daily.
“COVID-19 caused delays in cancer screening and non-emergency surgery, which led to a backlog of cases and delayed cancer presentations. Some studies have shown an increase in late-stage cancer presentations, which can be more time-consuming to diagnose in pathology. Both factors are contributing to higher traditional workloads for PathAs,” she added.
The pandemic, according to Gaburo, also led to increased duties for PathAs. “The pandemic also provided PathAs with opportunities to assist in developing new protocols such as: handling surgical specimens from COVID-19 patients, enhanced safety procedures in the laboratory, and autopsies on SARS-CoV-2 patients.”
But, with this expansion of duties also comes with the threat of burnout. “I believe the pandemic contributed to the burnout of PathAs in several ways. Many labs faced staffing challenges as employees contracted COVID-19, straining the existing workforce,” she noted.
“Some personnel struggled to balance their jobs as essential workers with providing virtual schooling for their children. Workloads increased when surgical cases resumed to catch up with the patient backlog. The incoming specimens were more complex due to delays in screening and advanced disease at presentation,” Gaburo added.
Job retention is an issue also explored by Gaburo in her Archives of Pathology and Laboratory Medicine paper. “Almost half of the laboratory professionals (including PathAs) surveyed by the ASCP addressed being underappreciated, especially compared with nursing and other allied health professionals.” She goes on to cite the risks of worker burnout, including adverse errors that could lead to liability of healthcare organizations.
Gaburo notes that burnout was an issue for PathAs before the COVID-19 pandemic “possibly due to a lack of job diversity and opportunities for growth,” she said. But the COVID-19 pandemic provided a unique opportunity for many PathAs, as well.
“The pandemic, while it brought challenges, also provided opportunities for PathAs to step into new, temporary roles early on when surgeries were limited, and clinics were closed. This job diversification may have helped develop resiliency and decrease burnout.”
PathA Shortage and Educational Opportunities
The COVID-19 pandemic required the entire healthcare industry to be flexible and expand in a short time. This, according to Gaburo, contributed to the growth of PathAs’ duties and could have helped with job retention as well.
When asked whether there was a shortage of PathAs in clinical laboratories and anatomic pathology groups, Gaburo said, “Though there are many open jobs for PathAs, our profession is fortunate in that we are not experiencing the same type of shortage as other laboratory professions. Instead of struggling to fill vacant positions, it seems many of the PathA openings are newly created positions. In fact, the new graduate employment rate of most, if not all, PathA programs is 100%.”
However, pandemic-related stresses and burnout have led to a shortage of anatomic pathologists, Gaburo notes. But in this she also sees new opportunities for PathAs.
“This is an area where the utilization of pathologists’ assistants has value for pathologists. PathAs, with support and mentorship, can provide assistance in many areas at a lower cost than pathologists, freeing up the pathologists to devote more time to patient care activities.”
As Gaburo concludes in her paper, “PathAs are qualified allied health professionals capable of handling a wide range of nontraditional roles in the pathology laboratory.” She goes on to note how practices can choose to mentor and support their PathAs by offering them mentorship and diverse educational opportunities.
“Over the last 15 years, the number of training programs for PathAs has more than doubled, from seven to 15. Class sizes have also increased to meet the growing demand for admission, which has become more and more competitive.
“The curricula include basic laboratory management classes, and some programs are considering incorporating ‘Business of Pathology’ courses as well. Many programs have expanded their clinical rotation sites, leading to opportunities for experienced PathAs to move into nontraditional teaching roles by becoming preceptors. However, there is still a need for more high-level administrative training opportunities,” Gaburo wrote.
Job satisfaction and retention increases quality for everyone involved. As clinical laboratories and anatomic pathology groups continue to support COVID-19 testing on top of traditional laboratory requirements, pathologist assistants have proven—and will continue to prove—what a valuable asset they are to clinical pathology practices.
Factors contributing to shortage of med techs and other lab scientists include limited training programs in clinical laboratory science, pay disparity, and staff retention, notes infectious disease specialist Judy Stone, MD
Staff shortages are a growing challenge for medical laboratories, and now the problem has grabbed the attention of a major media outlet.
In a story she penned for Forbes, titled, “We’re Facing a Critical Shortage of Medical Laboratory Professionals,” senior contributor and infectious disease specialist Judy Stone, MD, wrote, “Behind the scenes at every hospital are indispensable medical laboratory professionals. They performed an estimated 13 billion laboratory tests in the United States each year before COVID. Since the pandemic began, they have also conducted almost 997 million diagnostic tests for COVID-19. The accuracy and timeliness of lab tests are critically important, as they shape approximately two-thirds of all medical decisions made by physicians.”
Though Stone states in her Forbes article that clinical laboratories in both the US and Canada are facing staff shortages, she notes that the problem is more acute in the US.
As Dark Daily reported in February, the so-called “Great Resignation” caused by the COVID-19 pandemic has had a severe impact on clinical laboratory staffs, creating shortages of pathologists as well as of medical technologists, medical laboratory technicians, and other lab scientists who are vital to the nation’s network of clinical laboratories.
In her analysis, however, Stone accurately observes that the problem pre-dates the pandemic. For examples she cites two surveys conducted in 2018 by the American Society for Clinical Pathology (ASCP):
Many pathologists and clinical laboratory managers would agree that Stone is right. Dark Daily has repeatedly reported on growing staff shortages at clinical laboratories worldwide.
And in “Lab Staffing Shortages Reaching Dire Levels,” Dark Daily’s sister publication, The Dark Report, noted that CAP Today had characterized the current lab staffing shortage as going “from simmer to rolling boil” and that demand for medical technologists and other certified laboratory scientists far exceeds the supply. Consequently, many labs now use overtime and temp workers to handle daily testing, a strategy that has led to staff burnout and more turnover.
Why the Shortfall?
In her Forbes article, Stone notes the following as factors behind the shortages:
Decline in training programs. “There are only [approximately] 240 medical laboratory technician and scientist training programs in the US, a 7% drop from 2000,” Stone wrote, adding that some states have no training programs at all. She notes that lab technicians must have a two-year associate degree while it takes an average of five years of post-secondary education to obtain a lab science degree.
Pay disparities. Citing data from the ASCP, Stone wrote that “medical lab professionals are paid 40%-60% less than nurses, physical therapists, or pharmacists.” Moreover, given the high cost of training, “many don’t feel the salary is worth the high investment,” she added.
Staff retention. In the ASCP’s 2018 job satisfaction survey, 85.3% of respondents reported burnout from their jobs, 36.5% cited problems with inadequate staffing, and nearly that many complained that workloads were too high.
Inconsistent licensing requirements. These requirements “are different from state to state,” Stone wrote. For example, the American Society for Clinical Laboratory Science (ASCLS) notes that 11 states plus Puerto Rico mandate licensure of laboratory personnel whereas others do not. Each of those states has specific licensing requirements, and while most offer reciprocity for other state licenses, “California [for example] does not recognize any certification or any other state license.”
In a 2018 report, “Addressing the Clinical Laboratory Workforce Shortage,” the ASCLS cited other factors contributing to the shortages, including retirement of aging personnel and increased demand for lab services.
Possible Solutions
Stone suggested the following remedies:
Improve working conditions. “We need to reduce the stress and workload of the lab professionals before we reach a greater crisis,” Stone wrote.
Standardize state certification. This will facilitate “mobility of staff and flexibility in responding to needs,” Stone suggested.
Improve education and training opportunities. The ASCLS has called for clinical lab science to be included in the Title VII health professions program, which provides funding for healthcare training. Rodney Rohde, PhD, a clinical laboratory science professor at Texas State University, “also suggests outreach to middle and high school STEM programs, to familiarize students early with career opportunities in the medical laboratory profession,” Stone wrote.
Recruit foreign workers. Stone suggested this as an interim solution, with programs to help them acclimate to practice standards in the US.
It will likely take multiple solutions like these to address the Great Resignation and bring the nation’s clinical laboratory staffing levels back to full. In the meantime, across the nation, a majority of clinical laboratories and anatomic pathology groups operate short-staffed and use overtime and temporary workers as a partial answer to their staffing requirements.
