New Bay Area Lyme Foundation Study Shows Common FDA-Cleared Lyme Tests Miss 64-78% of Early Cases, Underscores Urgent Need for Improved Diagnostics

Research published in the Journal of Clinical Microbiology

PORTOLA VALLEY, Calif., April 21, 2026 –Bay Area Lyme Foundation, a national nonprofit and leading sponsor of tick-borne disease research in the US, today announced the publication of new research in the Journal of Clinical Microbiology based on data from its Lyme Disease Biobank. The study found that the commonly used FDA-cleared diagnostic testing methods available to providers and major national diagnostic laboratories are highly insensitive and miss 64-78% of early Lyme disease cases, including those who present with the characteristic erythema migrans (EM) Lyme rash.

“This study demonstrates that common two-tiered Lyme tests, utilized for decades, often fail to detect early Lyme disease and are leaving patients behind, highlighting a critical need for improved medical education on the limitations of current diagnostics,” said Liz Horn, PhD, MBI, Principal Investigator of Lyme Disease Biobank and lead author of the study. “Our findings also add to the evidence that improved diagnostics, ideally those that directly detect the bacteria that cause Lyme disease, are urgently needed.”

This large-scale, head-to-head study comparing 2 standard two-tiered testing (STTT) and 2 modified two-tiered testing (MTTT) diagnostic algorithms (the commonly used Lyme disease diagnostic algorithms) confirms that the sensitivity of two-tiered testing algorithms is low among patients with early infection. For the 107 early Lyme disease cases evaluated, the various testing algorithms missed 64-78% of early Lyme cases. Overall, only 39% (42/107) of participants with early Lyme disease were STTT or MTTT positive by any of the 4 algorithms.

“I wanted to be doing work that was driven by clinical need… and there are a lot of clinical needs in Lyme disease.”

– Peter Gwynne, PhD

For too many people with Lyme disease, the journey begins with uncertainty. A missed rash. A negative test. Symptoms that don’t make sense. A diagnosis that comes too late, or not at all. Bay Area Lyme Foundation believes this must change. And we believe change happens through funding rigorous science, innovative thinking, and supporting researchers willing to tackle the hardest questions head-on.

One of those scientists is Tufts researcher Peter Gwynne, PhD, a microbiologist whose work sits at the cutting edge of Lyme research and is the recipient of our 2022 Emerging Leader Award. We spoke with Dr. Gwynne to get an inside look at his work and understand how this may impact Lyme patients in the future. His focus is simple to state but complex to achieve: develop better diagnostics, identify meaningful biomarkers, and move the field toward treatments and even prevention strategies that could fundamentally reshape how Lyme disease is understood and managed.

Drawn to Lyme by the Urgency of the Need

Dr. Gwynne did not begin his career in Lyme disease. He trained in molecular microbiology, studying pathogens such as Salmonella and Staphylococcus, the bacteria responsible for serious infections, including those often acquired in hospital settings. But over time, he found himself seeking work that could make a tangible difference for patients.

For people living with or who suspect Lyme disease, getting a clear diagnosis can feel like the hardest part. Symptoms often mimic those of other illnesses, and traditional tests miss many cases.

In this episode of Ticktective™, Dr. Jyotsna Shah, President and Laboratory Director of IGeneX, shares with our host, Dana Parish, how her team is changing that—and how Bay Area Lyme Foundation helped make it possible.

Dr. Shah explains how partnerships between innovative labs like IGenex, Bay Area Lyme Foundation, and our Lyme Disease Biobank are helping deliver faster, more accurate diagnostics—and new hope for patients who’ve struggled for years to find answers.

Ten Years of Data, One Clear Message: We Need to Do Better for Lyme Patients

“The window for effective antibiotic treatment is narrow. Miss it—because of a false negative test, because symptoms are dismissed, or because follow-up doesn’t happen—and patients can develop persistent Lyme, which can be debilitating.”

– Dr. Liz Horn

After a decade of collecting blood samples, testing the samples, tracking patient outcomes, and analyzing data from more than 800 participants, the numbers tell a powerful story about the gaps in our understanding of how we diagnose and treat early Lyme disease. And it’s made all the more urgent by this summer’s explosion in blacklegged (deer) tick populations across endemic areas.

Our latest Lyme Disease Biobank study looked at more than 250 patients with early Lyme disease on Long Island and in Central Wisconsin who provided a blood draw at enrollment and a second blood draw three months later. Published recently in Frontiers in Medicine, these 10 years of data confirm a few important points that have been known in the Lyme field for years, but the wider medical community may not be aware of.

Journal of Clinical Microbiology Studies Demonstrate Two Investigational Diagnostics Outperform Current Tests in Detecting Early Lyme Disease

Studies utilize Bay Area Lyme Foundation’s Lyme Disease Biobank samples to point to the promise of single-tier diagnostics to potentially transform early detection

PORTOLA VALLEY, Calif., October 9, 2025 — Bay Area Lyme Foundation, the leading nonprofit funder of Lyme disease research in the US, today announced results from two independent studies published in Journal of Clinical Microbiology, conducted by researchers at Tufts University School of Medicine, and Kephera Diagnostics, respectively, demonstrating the potential of novel investigational single-tier Lyme disease tests to improve accuracy in the earliest stages of infection. Each study uses well-characterized samples from Bay Area Lyme Foundation’s Lyme Disease Biobank and demonstrated unprecedented accuracy, far exceeding the current CDC-recommended Lyme disease two-tier test, which can miss up to 70% of early-stage cases as well as later-stage cases.

“The CDC’s standard two-tier Lyme diagnostic misses the majority of early cases, delaying treatment and increasing the risk of developing persistent, debilitating symptoms for patients. The two novel single-tier assays—while not yet FDA-cleared for clinical use—point to a future where Lyme disease can be diagnosed quickly, accurately, and with a single test,” Liz Horn, PhD, MBI, a coauthor on both studies, and Principal Investigator of Lyme Disease Biobank, a Bay Area Lyme Foundation program that provides much-needed samples to approved researchers working to better understand tick-borne diseases and develop improved diagnostic tests and therapeutics. “These single tier tests, like InBios Lyme Detect™ and Kephera’s Hybrid Lyme ELISA could mark a turning point for Lyme diagnostics, giving physicians and patients more accurate tools that are urgently needed.”

The first study, evaluating the InBios Lyme Detect™ Multiplex ELISA, was conducted by Pete Gwynne, PhD, a 2022 Bay Area Lyme Emerging Leader Award (ELA) winner, and colleagues at Tufts University School of Medicine. Using samples from the Lyme Disease Biobank, this new diagnostic correctly identified all two-tier positive samples evaluated in the study, while also detecting 21 of 79 clinically diagnosed patients who were missed by following the current CDC guidance for testing using FDA-cleared standard two-tier tests (STTT) and had erythema migrans (EM) skin lesions. Importantly, the InBios test maintained >99% specificity, with only one false positive across more than 200 control and lookalike disease samples and was shown to be highly reproducible.

New Bay Area Lyme Foundation Study Reports That Only One-Third of Early Lyme Patients with On-Going Symptoms Followed up with their Healthcare Providers

The new research, published in Frontiers in Medicine, points to need for greater follow-up from medical professionals to address potential treatment failures.

PORTOLA VALLEY, Calif., July 10, 2025—Bay Area Lyme Foundation, a leading sponsor of Lyme disease research in the US, announced the publication of new research in Frontiers in Medicine based on data from Bay Area Lyme Foundation’s Lyme Disease Biobank. This large-scale study conducted over 10 years at sites on the East Coast and the Upper Midwest demonstrates the need for improved diagnostics and increased follow-up by medical professionals for Lyme disease patients.

Only one-fifth of study participants (23%), enrolled with signs and symptoms of early Lyme, were positive by the CDC’s standard two-tiered test for Lyme disease, which supports previous research that found that it misses up to 70% of cases of early-stage Lyme disease. Further, approximately 1 in 5 patients reported ongoing symptoms at 3 months, including joint pain, fatigue, and muscle pain yet only one-third (35%) of these participants followed up with their healthcare providers about these ongoing symptoms. Due to difficulties in diagnosing Lyme disease and resulting treatment delays, as many as two million people may suffer from persistent Lyme disease, which can be debilitating.

Accurate, timely detection of Lyme disease is critical to preventing long-term complications. Moreover, follow-up from medical professionals with all patients after they complete antibiotic treatment could improve outcomes and reduce the burden of Lyme disease,” said lead author Liz Horn, PhD, MBI, Principal Investigator of Lyme Disease Biobank, a Bay Area Lyme Foundation program which helps to accelerate research by collecting, storing and providing much-needed human biological samples for use in research. “Our data also confirm the limitations of serology testing in early Lyme disease and after antibiotic treatment.”

There is an immense need for better Lyme disease tests. Today’s standard-of-care tests miss too many cases at all stages of Lyme disease, including as many as 70% of early Lyme cases.

“With Lyme disease cases rising steadily across the U.S., the need for accurate and timely diagnostic tools has never been greater,” said Katariina Tuovinen, research grant director, Bay Area Lyme Foundation. “Dr. Wang’s pioneering work epitomizes the essence of this award as it applies innovation from other infectious diseases in an effort to enhance outcomes for patients affected by Lyme disease.”

The Numbers Don’t Lie: Why the NIH Consistently Underfunds Research into Lyme Disease

By Bay Area Lyme Foundation

An In-depth Interview with Kris Newby, Author of “Bitten”

“We need to let the NIH know that we’re watching them, and we want results.”

– Kris Newby

Kris Newby, author of ‘Bitten,’ is investigating government spending on Lyme disease research, which is strongly influenced by the flawed original disease definition of Lyme disease. She summarizes the impact of the 2018 Tick-Borne Disease Working Group’s report, explains where research funding has and is currently being directed, and calls for money to be spent on better diagnostics and treatments for Lyme disease sufferers instead. Kris explores potential actions that Lyme patients can take to help direct the course of funding, such as communicating with Congress, supporting advocacy groups, and donating to research organizations.

The views and opinions expressed in this article are those of the interviewee and do not necessarily reflect the views or positions of Bay Area Lyme Foundation.

Kris Newby is watching our government, and watching quite closely. She has a lot to say about how government money is spent on a disease that, according to CDC estimates, infects almost 500,000 people annually in the US, causing untold pain, suffering, loss of livelihood, and, in extreme cases, severe mental illness, including suicidal and homicidal events.

Of course, we are talking about Lyme disease—the pariah of infection-associated chronic conditions.
