Summary: Researchers at George Mason University have been awarded over $1 million to develop a urine-based Lyme disease test that provides earlier and more accurate results compared to current methods.


  1. The new urine test developed by Mason researchers detects Lyme disease-causing bacteria (Borrelia species).
  2. The study includes the pilot of a collapsible urine collection cup that can be mailed to a lab, facilitating easier sample collection and diagnosis through telehealth, which enhances patient privacy and convenience.
  3. This advancement in Lyme disease testing aims to determine earlier treatments, potentially preventing the long-term debilitating effects of the disease.

George Mason University researchers have received a $1,176,645 grant in federal funding from the U.S. Department of the Army to revolutionize Lyme disease detection and diagnosis with urine testing. The College of Science and College of Public Health aim to harness the many advantages of urine testing over other methods and increase mainstream adoption.  

“We have developed a urine test for Lyme disease that detects the bacteria (Borrelia species) that causes Lyme disease, making it a direct test to confirm an infection soon after the tick bite. This leads to earlier treatment when necessary and could prevent the long-term debilitating effects of the disease,” says Alessandra Luchini, systems biology professor in the College of Science and Mason’s principal investigator. 

Improving Lyme Disease Testing

The current standard of care test for potential Lyme disease is an antibody blood test that measures the immune system response to the bacteria that cause Lyme disease. In contrast, the Mason test detects molecules derived from the bacteria themselves, which have the advantage of high specificity (accuracy) and early detection. The Mason test matches the exact amino acid sequences (the building blocks of the bacterial molecules) that are found only in Borrelia and not in other organisms. For example, one of the proteins the Mason scientists studied is part of the Borrelia flagellum, which allows the bacterium to move around the body.

Urine Testing for Lyme Disease

In Mason’s clinical research trials, urine tests had a 90% true positive rate (sensitivity) and close to 100% specificity (true negative rate). Researchers will use banked samples from cross-sectional and longitudinal studies of acute Lyme patients from the Lyme Disease Biobank and banked specimens from Johns Hopkins University, respectively, who are recognized leader in clinical Lyme disease research. 

Utilizing her 15 years of Lyme disease bacteria (Borrelia) research, Ashley Groshong, PhD, unit chief of the Bacterial Physiology and Metabolism Section of the National Institute of Allergy and Infectious Diseases, a part of the National Institutes of Health, is collaborating on the project by evaluating the suitability of diagnostic indicators based on bacterial physiology.  

Additionally, the Mason study will pilot a collapsible urine collection cup shipped to a lab through the mail, making collection and diagnosis easier for more people to access through telehealth. 

“A urine cup will offer a private, comfortable and convenient way to collect the sample at home without compromising the accuracy of the lab test,” says Lance Liotta, professor in the College of Science, co-director of Mason’s Center for Applied Proteomics and Molecular Medicine, and co-investigator on the study. “Shipped in a semi-dry state that will preserve target proteins and protects again specimen degradation, this approach will improve specificity which has been a weakness of previous testing approaches.” 

Lyme Disease in the U.S. 

Lyme disease is the most common animal-to-human transmitted disease in the United States with approximately 476,000 people diagnosed and treated each year—and it is on the rise. If not treated quickly and properly, those bitten can suffer from prolonged symptoms (called Post-Treatment Lyme Disease Syndrome), such as concentration and memory issues, dizziness, fatigue, body aches, depression, and difficulty sleeping. 

“This is a significant collaboration to advance diagnostics for Lyme disease. In my capacity as an epidemiologist, I am thrilled to work with Drs. Luchini, Liotta, and Espina, and Dr. Krall in her capacity as a biostatistician. This study will have a major impact on the timely diagnosis of Lyme,” says Melissa J. Perry, dean of the College of Public Health and co-investigator of the study. 

This three-year study will take place in the same Mason CAP/CLIA Clinical Proteomics Laboratory that implemented the innovative saliva COVID test. The lab is run by Virginia Espina, who is a collaborator on the grant.
