Wondering how you can find out if you have this disease? Well, the answer may lie in a tick bite, but many cases do not recall ever being bitten by a tick as they are very small and stealthy critters. If you feel you have contracted this disease you may be urged to receive a blood test up to four weeks after the developed infection to search for antibodies averse to the spirochete, Borrelia burgdorferi. The blood test would be either an ELISA or Western blot test.
