“This is solvable. It just needs continued focus.”

– David Walsey, Executive Director, Bay Area Lyme Foundation

For many Lyme disease survivors and families, the journey toward answers can feel overwhelming, confusing, and painfully isolating. Symptoms often linger for years. Tests come back negative despite debilitating illness. Patients bounce from doctor to doctor searching for someone who understands what they are experiencing.

For David Walsey, Executive Director of Bay Area Lyme Foundation, this challenge is deeply personal, as he shared on the Love, Hope, Lyme Podcast.

Before stepping into his leadership role at the Foundation, Walsey and his family spent nearly a decade navigating the complexities of tick-borne illness after one of their children became severely ill.

“It’s really a journey not to wish upon anybody,” Walsey shared. “From getting the diagnosis, to figuring out the treatment, to just knowing really how to treat.”

A behind-the-scenes look at how Wauchita Green and Pauline Lui help turn patients’ tissue donations into research that is changing the future of Lyme disease.

Lyme Disease Biobank, a program of Bay Area Lyme Foundation, partners with the National Disease Research Interchange (NDRI) to help advance Lyme disease research. Together, they enable patients to contribute tissue samples, collected during surgery or after death, which the Biobank shares with approved scientists studying infection and immune response. NDRI’s nationwide recovery network ensures these precious donations are handled with care and respect. This partnership helps turn patient generosity into real progress, accelerating the search for better diagnostics, treatments, and ultimately, a cure.

The Biobank also partners with MyLymeData, allowing Lyme patients registered with the Biobank to link their MyLymeData profile to their tissue donation, if desired.

When families whose lives have been impacted by Lyme disease call to talk about donating tissue, they’re often overwhelmed. But thankfully, the NDRI private donor team is standing by 24/7/365 to help. Patients and families typically want to know:

“How much does this cost?”
“What actually happens?”
“Is this going to be complicated?”

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.

Improving Lyme Diagnostics, Biomarkers, and Treatment: Inside Dr. Peter Gwynne’s Research

“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.

FOR IMMEDIATE RELEASE

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.
