Ehrlichia spp


Ehrlichia species PCR Test


The Ehrlichia species PCR test is designed to detect all pathogenic Ehrlichia species. Positive results are confirmed by DNA sequencing to identify the infecting species. It is recommended for diagnostic testing for symptomatic patients with risk of exposure.

Why do I need this test?

Ehrlichia species infection mimics many other conditions, including other chronic infections and a number of autoimmune diseases. If you are experiencing hard-to-diagnose chronic symptoms and have had a recent tick attachment or live in a region endemic for Ehrlichia species in ticks, you should consider testing for Ehrlichia infection. Symptoms can range from mild to serious illness characterized by fever, headache, confusion, chills, malaise, muscle pain, rash, upset stomach, conjunctivitis and other conditions that may require immediate medical attention. This zoonotic infection is primarily transmitted to humans by lone star ticks but can also be transmitted through blood transfusion.  Clinical presentations may be more severe when co-infected with multiple tick-borne pathogens.
