IGeneX is a leading testing lab for Lyme Disease, Relapsing Fever, Babesia, Bartonella, Rickettsia, and other Tick-Borne diseases.



For over 25 years, IGeneX has been the global leader in the research and development of tests that accurately detect Lyme disease, Relapsing Fever, and other tick-borne diseases. Tick-borne illnesses can affect every part of your life, and without effective diagnosis and treatment, symptoms can often worsen and progress into severe and even life-threatening health issues. And when you can’t find the cause or a way to get better, your quality of life suffers. At IGeneX, we make it our singular mission to offer best-in-class testing for tick-borne diseases that delivers the most comprehensive and accurate results possible, so you can find the right treatment path to restore your health and get back to enjoying your life.
