Is there a test to diagnose tick-borne diseases?

There is. We use the IDEX SNAP 4Dx here in the clinic, and it tests for heartworm disease and the common tick-borne diseases that we see in this area. So we commonly use it to also test for heartworm disease.

Yes, there is a test to diagnose tick-borne diseases. In middle Tennessee, for example, about 9% of the tests run on pets for heartworm and tick-borne diseases come back positive for tick-borne diseases. The most common tick-borne disease in Tennessee is Ehrlichia, but Lyme disease is occasionally seen as well.
