Tick Test- Rare Pathogen Panels

We offer additional testing for rare and other uncharacterized tick-borne bacteria and viruses. Additional testing is offered as an extension to our Universal Tick Test service. We may recommend one or more of these tests if a rare, nonpathogenic or uncharacterized pathogen is suspected. Please contact us for a recommendation. Tests typically require 3 business days.

RNA Virus Tests ($50 each)

Colorado Tick Fever (CTF) virus test

Tick Species: Dermacentor andersoni/Rocky Mtn. Wood tick


Location: Exclusively found in the western United States or western Canada at higher elevations (4,000‒10,000 ft. above sea level).
