The Lyme Disease (Borrelia Antibodies) IgG/IgM test is a blood test that detects antibodies produced by the immune system in response to infection with Borrelia bacteria. These bacteria are transmitted through tick bites and are responsible for Lyme disease.
IgM antibodies typically appear in the early stages of infection, while IgG antibodies develop later and may persist for months or years. Testing both antibody types provides insight into the timing and likelihood of exposure.
This test is commonly used when Lyme disease is suspected based on symptoms, exposure history or unexplained multi-system illness.
You may need this test if you have symptoms following a tick bite or if you live in or have travelled to areas where Lyme disease is prevalent. Lyme disease can affect the skin, joints, nervous system and heart if left untreated.
Early identification supports timely antibiotic treatment and reduces the risk of long-term complications. Testing is also useful when symptoms are non-specific and other causes have been excluded.
Symptoms and scenarios where testing is recommended:
You can attend one of our UK partner clinics or arrange a home or hotel visit with a mobile phlebotomist.
Negative Result
No Borrelia IgG or IgM antibodies detected.
This suggests no evidence of Lyme disease, though very early infection cannot be fully excluded.
IgM Positive / IgG Negative
May indicate recent or early infection.
Clinical correlation and repeat testing may be advised.
IgG Positive (with or without IgM)
Suggests past or established infection.
Interpretation depends on symptoms, timing and treatment history.
Antibody results should always be interpreted alongside clinical findings.

Where possible, attend your blood test between 7am and 12pm. Please wait until any short-term illness or infection has fully resolved before testing. Avoid intense exercise for 24–48 hours beforehand, as this can affect certain markers.
Fasting is not always required, but some tests may recommend it. If fasting is advised, avoid food for 8–12 hours before your appointment and drink water only. Stay well hydrated, as this helps with sample collection and accuracy.
Continue prescribed medications unless advised otherwise by your clinician. Avoid vitamin, mineral, or biotin supplements for at least 24–48 hours before your test, as these can interfere with results. If you are unsure about any medication or supplement, please let us know before your appointment.
For hormone-related tests, timing within your menstrual cycle may be important. If relevant, follow any specific guidance provided on your test page.
If you have any questions or special circumstances, our team is happy to advise before your appointment.
