Tick Bite Blood Test: What to Order and When to Test

The right test depends on timing: DNA tests screen for Borrelia burgdorferi genetic material associated with active infection, while IgM/IgG antibody immunoblots measure an immune response that develops over weeks. A combined option like the Lyme Disease Direct and Indirect Panel covers both approaches in a single order. Share your bite date and any symptoms with your doctor so they can help you pick the most informative test and window.

Antibody tests need time, IgM antibodies are associated with recent infection, and IgG antibodies usually appear weeks after infection, so testing in the first days after a bite can be too early for an immune response to register. DNA-based tests screen for bacterial genetic material directly and sit differently on the exposure timeline. Your doctor can help you decide whether to test now, retest later, or do both.

Yes, you can order these Lyme disease tests online in a few clicks and complete the blood draw at a local lab, with no doctor's appointment needed to place the order. Testing is confidential and results come back to you directly. Bring any positive or unclear result to your doctor, who can interpret it against your bite timeline and symptoms.

Flu-like symptoms, fever, chills, fatigue, body aches, and headache, are the signs most often associated with early Lyme disease, along with a rash that can resemble a bull's-eye, though the rash does not appear in every case. Joint pain and swelling, particularly in the knees, are associated with later stages. If any of these follow outdoor exposure, testing gives you and your doctor objective data to review.

In most US states, yes, but direct-to-consumer lab testing is restricted or prohibited in New York, New Jersey, and Rhode Island, so residents of those states may be blocked at the partner's checkout. Elsewhere, you can typically order online and visit a nearby lab location for your draw. Check the partner site for locations near you.
