FDA Grants Marketing Authorization to Diagnostic Tests for Chlamydia and Gonorrhea with At-Home Sample Collection

FDA says the move will make it easier to gain authorization for other clinical laboratory tests to utilize at-home collection kits In another sign of how diagnostic testing is responding to changing consumer preferences, the US Food and Drug Administration (FDA) granted marketing authorization to LetsGetChecked for the company’s Simple 2 test for chlamydia and gonorrhea, which includes at-home collection of samples sent to the test developer’s clinical laboratories in the US and in Ireland....

HRSA Updates Cervical Cancer Screening Guidelines, Endorses HPV Self-Collection and Mandates Insurance Coverage by 2027

Federal health officials have updated cervical cancer screening guidelines to add HPV self-collection and require insurer coverage starting in 2027, a shift that could significantly impact testing volumes and workflows for clinical laboratories.

In a move that could significantly reshape testing volumes, workflows, and access strategies for clinical laboratories, the US Health Resources and Services Administration (HRSA) said in a press release that it has issued updated cervical cancer screening guidelines that formally introduce patient self-collection as a new screening option..

Under the updated guidance, high-risk human papillomavirus (hrHPV) testing—using either clinician-collected or patient-collected samples—is now the preferred screening method for average-risk women ages 30 to 65, while Pap testing remains an option. For women ages 21 to 29, Pap testing continues to be recommended.

The guideline also includes a major payer-facing provision that lab leaders should note. HRSA said most insurance plans will be required to cover not only the screening itself, but also any additional testing needed to complete the diagnostic process following an abnormal result. That coverage requirement takes effect January 1, 2027, reducing patient cost barriers that have historically limited follow-up testing volumes.

“These updates represent a significant step forward in cervical cancer screening and will improve screening rates and save lives,” HRSA Administrator Tom Engels said, adding that expanded options and reduced financial barriers allow more women to “take an active role in protecting their health and their future.” (Photo credit: HRSA)

HRSA Update Sets Stage for Insurer-Covered At-Home Testing Starting in 2027

An article from ABC News said the HRSA update aligns federal preventive guidance with recent FDA approvals that now allow both in-clinic and at-home self-collection for HPV testing. The January 2027 deadline for private insurers is expected to accelerate adoption of home-based and alternative specimen collection models.

“The addition of self-collection really empowers women to make this choice for themselves,” Ann Sheehy, MD, HRSA’s chief medical officer, told ABC News. “We do retain the option for Pap smear … this is just an additional choice for women.”

ABC News stated the preferred screening cadence for women ages 30 to 65 is now primary hrHPV testing every five years, whether the sample is collected by a clinician or by the patient. Alternative pathways—co-testing every five years or Pap testing every three years—remain in place if HPV testing is unavailable, preserving flexibility for labs at different stages of HPV test adoption.

HRSA officials emphasized that the goal is expanded access, not replacement of existing workflows. Engels told ABC News that self-collection could help reach women who have “been falling through the cracks,” adding, “By doing that, we’re going to save lives.”

ABC News noted the guidance also clarifies insurer obligations for follow-up diagnostics, including Pap testing, biopsy, and laboratory work, a move designed to prevent cost-sharing from disrupting care pathways. Separate HRSA rules now also require coverage of patient navigation services, which may further increase completed diagnostic testing after abnormal screens.

The American Cancer Society’s (ACS) December 2025 guideline update helped shape the federal move, ABC News said, citing evidence that self-collection improves access without sacrificing accuracy. “The combination of good evidence of the benefits of self-collection, which include increased access to cervical cancer screening, combined with FDA approval, led the ACS and HRSA to include self-collection,” said Robert Smith PhD, senior vice president of early cancer detection science at the ACS.

For lab professionals, HRSA’s announcement underscores a coming shift: broader HPV test demand, increased importance of validated self-collection workflows, and potentially higher follow-up testing volumes as cost barriers fall and screening gaps narrow.

Interest in Purchasing/Performing At-home Medical Tests Grows Among Older Adults, according to University of Michigan Poll

As clinical laboratory self-testing expands, sharing of test results with healthcare providers becomes even more essential to optimize health outcomes

Survey data collected by the University of Michigan’s Institute for Healthcare Policy and Innovation (IHPI) indicates that consumer interest in direct-to-consumer (DTC) medical self-testing is growing. In fact, DTC testing appears to be more popular ever, even among older adults who were asked how they feel about performing clinical laboratory self-testing and specimen collecting for certain illnesses.

With support from AARP and the Michigan Medicine Department of Communications, more than 2,000 older adults between the ages of 50 and 80 responded to the IHPI’s National Poll on Healthy Aging (NPHA) either online or by telephone.

According Michigan Medicine’s MHealth Lab, “82% of older adults say that in the future, they would be somewhat or very interested in taking a medical test at home.”

Dark Daily has written regularly about this trend and how leaders need a strategy to serve this class of consumer. That strategy could include collecting the self-test results from consumers and keeping a complete record of consumers’ clinical laboratory test results from inpatient, outpatient, and self-test settings.

Jeffrey Kullgren, MD

“As more companies bring these direct-to-consumer [medical] tests to market and buy ads promoting them, it’s important for healthcare providers and policymakers to understand what patients might be purchasing, what they’re doing with the results, and how that fits into the broader clinical and regulatory picture,” said research scientist Jeffrey Kullgren, MD (above), Associate Professor of Internal Medicine and Health Management and Policy at the University of Michigan in a press release. Clinical laboratories may find opportunities to support patients’ self-testing in tandem with the physicians who treat them. (Photo copyright: University of Michigan.)

Importance of Sharing Clinical Laboratory Self-Test Results

Individuals responding to the poll were asked only about medical laboratory self-tests they had purchased themselves either online or at a retail store. Tests provided to respondents by a healthcare provider or given to them for free were not part of the survey.

The researchers discovered that 48% of respondents had purchased at least one variety of at-home health tests in the past. The types of tests bought included:

  • COVID-19 (32%),
  • DNA/genetic kits (17%),
  • Cancer tests, such as colon or prostate (6%),
  • Tests for infections other than COVID-19, such as urinary tract infections or HIV (4%), and
  • Other types of at-home tests, including those for allergies and food sensitivities (10%).

Approximately 82% of the respondents said they would be somewhat or very interested in taking at-home medical tests and nine out of 10 believed the test results should be shared with their doctors. But only 55% of respondents who had taken an at-home medical test and received positive results for infection other than COVID-19 had shared those results with their primary care physician.

However, 90% of respondents who had purchased a self-test for cancer screening did provide their doctors with the results.

“As we have seen in COVID-19, it’s important to share results from a home test with a provider so that it can be used to guide your care and be counted in official statistics,” said Jeffrey Kullgren, MD, Associate Professor of Internal Medicine and Health Management and Policy at the University of Michigan in an IHPI press release. Kullgren, a primary care physician and healthcare researcher at Michigan Medicine and the VA Ann Arbor Healthcare System, directed the IHPI poll.

Not All Medical Self-Tests Are Regulated by the FDA

The most prominent reason for wanting to use at-home tests was convenience and 59% of those surveyed felt that the results could be trusted. 

The poll also found that 53% of older adults believe at-home medical tests are regulated by the federal government, which isn’t always the case. Many at-home medical tests are reviewed by the federal US Food and Drug Administration (FDA), but not all such tests receive full FDA review.

The FDA, however, offers an online, searchable database consumers can use to determine if a certain over-the-counter test is regulated by the FDA.  

“Home tests can be a convenient way for older adults to check if they have an illness, such as COVID-19” stated Indira Venkat, Senior Vice President, AARP Research in the press release. “But consumers should make sure they know whether the test they are taking is FDA-approved, and how their health or genetic information might be shared.”

Other interesting outcomes of the research include:

  • The purchasing of at-home COVID-19 tests was highest among those between the ages of 50 and 64 when compared to the 65 to 80 age group, but there were no age differences for other types of at-home tests.
  • Respondents who are married or have who more education and/or higher household incomes were more likely to have purchased at-home tests.
  • Blacks were less likely to buy at-home medical tests than Whites or Hispanics.
  • Interest for at-home tests was higher among women than men.
  • Advertising swayed 44% of purchasing respondents to buy a DNA test and 11% to buy a cancer screening test.

Are DTC Home Tests as Accurate as Clinical Laboratory Testing?

At-home medical self-testing and sample collection is becoming accepted and established with consumers and the medical community, which is drawing attention to the accuracy of these tests and how clinical laboratories are being affected by the trend.

In “Patient Safety Organization Releases Report Rating COVID-19 Home Tests for Ease of Use,” we covered the Emergency Care Research Institute’s investigation into certain COVID-19 rapid antigen tests to find out how easy—or not—they are to use and what that means for the accuracy of the tests’ results.

And in “‘Femtech’ Diagnostic Start-up Firms Want to Provide Women with At-Home Tests for Health Conditions That Currently Require Tests Done by Clinical Laboratories,” we reported how growth in this segment could lead to new diagnostic tests that could boost a medical laboratory’s bottom line or, conversely, reduce its revenue as patients self-diagnose urinary tract infections (UTIs), yeast infections, and other conditions through at-home DTC testing.

The findings of this recent survey of older consumers is just the latest evidence that at-home self-testing for everything from COVID to cancer is here to stay. Clinical laboratories should be looking for ways to serve this patient population and the physicians who treat them.

FDA Expands Approval of Gastric Emptying Breath Test for Gastroparesis to Include At-home Administration Under Virtual Supervision

It may not be a boom trend, but more non-invasive diagnostic tests are coming to market as clinical laboratory tests that use breath as the specimen

Here’s a development that reinforces two important trends in diagnostics: non-invasive clinical laboratory assays and patient-self testing. Recently, the FDA expanded the clearance of one diagnostic test to allow patients to collect their own breath specimen at home under the supervision of the test manufacturer’s telehealth team.

The C-Spirulina Gastric Emptying Breath Test (GEBT) breath test from Cairn Diagnostics initially received federal Food and Drug Administration (FDA) approval in 2015. At that time, the test was required to be administered “at a physician’s office, a laboratory collection center, or in a tertiary care setting,” according to a 2016 news release.

Recently, however, the FDA announced it has “expanded the approval of the company’s 13C-Spirulina Gastric Emptying Breath Test (GEBT) to now include ‘at home’ administration under virtual supervision of Cairn Diagnostics.”

Self-administration of at-home tests by patients guided virtually by healthcare professionals is a major advancement in telehealth. But will this virtual-healthcare method be popular with both patients and their physicians?

Clinical Laboratory Diagnostics and Telehealth

Spurring a far greater acceptance of telehealth among patients and healthcare providers is one of the many ways the COVID-19 pandemic has impacted healthcare.

“Telehealth, particularly during the COVID-19 pandemic, has emerged as a preferred option for healthcare providers,” noted Kerry Bush, President and COO of Cairn Diagnostics, in a 2021 news release

Cairn’s GEBT detects gastroparesis, a disease which, according to the NIH National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK), affects 50 people in every 100,000. According to the CDC, it is also sometimes a complication of diabetes. Symptoms include nausea, heartburn, bloating, a feeling of fullness long after eating a meal, vomiting, belching, and pain in the upper abdomen, the NIDDK notes.

In people with gastroparesis—sometimes called “delayed gastric emptying”—muscles that normally move food from the stomach to the small intestine do not work as they should, and the food remains in the stomach for too long. The traditional diagnostic tool used to diagnose gastroparesis is scintigraphy. The patient consumes a meal that has radioactive material mixed in and the digestion process is observed using a nuclear medicine camera as the material is eliminated through the bowels.

Cairn Diagnostics’ C-Spirulina Gastric Emptying Breath Test

Virtual Telehealth GEBT versus Scintigraphy

The telehealth process for Cairn Diagnostic’s Gastric Emptying Breath Test (GEBT) differs significantly from traditional scintigraphy testing. Once a physician prescribes the test, Cairn’s telehealth team contacts the patient to describe the virtual process. The team then ships the at-home test kit to the patient. To complete the testing, Cairn provides the patient with a web-based link to a secure audio/video platform.

During administration of the GEBT, a Cairn technician coaches the patient and supervises via video. Once the test is complete, the patient returns the breath samples to the CLIA-certified clinical laboratory by overnight courier. The test results are sent to the prescribing physician within 24-48 hours after the lab receives the samples.

Discovering New Uses for Breath as a Specimen for Clinical Laboratory Testing

For obvious reasons, patients prefer diagnostics that use specimens obtained noninvasively. GEBT is the latest in a growing list of diagnostic tests that use breath as a specimen.

For example, at Johns Hopkins clinicians employ breath testing to diagnose several conditions, including:

Each of these tests involves the patient consuming a particular substance, technicians capturing breath samples at certain intervals, and clinical laboratory personnel analyzing the samples to look for indicators of disease or intolerance.

New Types of Breath Tests

Breath samples are commonly used to diagnose gastrointestinal issues, but researchers also are seeking methods of using them to diagnose and monitor respiratory conditions as well.

In a recent study published in Nature Nanotechnology, scientists explored how breath can be used to monitor respiratory disease, noting that although breath contains numerous volatile metabolites, it is rarely used clinically because biomarkers have not been identified.

“Here we engineered breath biomarkers for respiratory disease by local delivery of protease-sensing nanoparticles to the lungs. The nanosensors shed volatile reporters upon cleavage by neutrophil elastase, an inflammation-associated protease with elevated activity in lung diseases such as bacterial infection and alpha-1 antitrypsin deficiency,” the researchers wrote.

Indeed, the search for new ways to use breath as a biological sample is being pursued by numerous groups and organizations. Owlstone Medical in the UK, for example, is developing breathalyzer tests for the detection of cancer as well as inflammatory and infectious disease.

“Exhaled breath is more than just air,” notes the company’s website. “It contains over 1,000 volatile organic compounds (VOCs) as well as microscopic aerosol particles, also known as respiratory droplets, originating from the lungs and airways.”

Analyzing breath allows for the:

  • investigation of biomarkers of disease,
  • patient stratification by phenotype,
  • detection and monitoring treatment response, and
  • measurement of exposure to harmful substances.

In fact, so many studies on using breath as a specimen have been conducted that in “Breath Biomarkers in Asthma: We’re Getting Answers, But What Are the Important Questions?” researchers Peter J. Sterk, PhD, Professor of Pulmonology at Amsterdam University Medical Centers, and immunity and respiratory medicine specialist Stephen J. Fowler, MD, FRCP, Professor of Respiratory Medicine at the University of Manchester in the UK suggested that systematic reviews are now feasible. They published their article in the European Respiratory Journal.

“Whilst we are still in this discovery stage it is time to refine our study designs so that we can make progress towards tailored clinical application,” they wrote. “Breathomics is perhaps at the ‘end of the beginning’ for asthma at least; it has a ‘sexy’ name, some promising and consistent findings, and the key questions are at least being recognized.”

Better for Patients, Clinicians, and Clinical Laboratories

Virtual telehealth tests, ordered by physicians, administered at home, and interpreted in CLIA-certified clinical laboratories, is a trend pathologists may want to watch carefully, along with the development of other tests that use human breath as the specimen. 

Less invasive, more personalized diagnostic tools that can be administered at home are better for patients. When those tools also provide detailed information, clinicians can make better decisions regarding care. Clinical laboratories that approach the use of at-home tests creatively, and which can accurately and quickly process these new types of tests, may have a market advantage and an opportunity to expand and grow.
