The Lyme disease antibody test checks your blood for antibodies your immune system makes after exposure to Borrelia burgdorferi, the bacterium spread by certain tick bites. It is usually ordered when someone has symptoms such as a rash, fever, or joint aches and may have been bitten by a tick.

What it measures

  • IgM antibodies — Early immune response; can appear within weeks of infection.
  • IgG antibodies — Later immune response; often used to confirm exposure over time.
  • Enzyme immunoassay (EIA) — First-step screening test that detects antibodies broadly.
  • Western blot — Second-step test that checks for specific antibody patterns.

Who it is for

A doctor or other clinician typically orders this test when symptoms and possible tick exposure suggest Lyme disease. It is not a routine screening test for people without symptoms.

Preparation

No fasting or special preparation is needed. Tell your clinician about any antibiotics you are taking, since they can affect antibody results.

Results and what they mean

Results are usually reported as negative, positive, or equivocal, sometimes with individual band patterns from a Western blot. A clinician interprets these results alongside your symptoms and exposure history. This is general information, not medical advice; discuss your results with a qualified healthcare professional.

Requesting the Lyme Disease Antibody Test in Washington

Order online, choose a certified collection site in Washington, and review results through a secure portal. No referral is required, and orders are processed confidentially. Because the region is uneven, coastal metros, inland towns, and rural counties with very different access to testing — worth planning around when you book.

Frequently asked questions

How soon after a tick bite can this test be positive?

It may take several weeks after infection for antibodies to reach detectable levels, so a test very soon after a bite can be negative even if infection occurred.

Does a positive result always mean I have Lyme disease?

No. A positive result shows exposure to the bacterium, but a clinician must consider symptoms and other findings to interpret it.

Can antibiotics affect the test result?

Yes. Antibiotics taken before testing may lower antibody levels and affect results, so tell your clinician about any recent antibiotic use.

Do I need to fast before this test?

No fasting is required. You can eat and drink normally unless your clinician gives other instructions.
