About the test

This test checks for Lyme disease, which is spread by ticks carrying Borrelia burgdorferi. It uses a method called Immunoblot to look for specific antibodies in your blood with high accuracy. This is usually done to confirm results from other tests like EIA or IFA.

Who might consider it:

This test is recommended if you've been in areas where Lyme disease is common and have symptoms such as:

Fever
Headache
Fatigue
Skin rash
Muscle and joint aches

Included biomarkers & Reference ranges

Biomarker	Reference range
18 KD (IgG) Band Shows whether your IgG antibodies react to the 18 kD protein of the Lyme bacterium, one band read as part of a Lyme disease immunoblot pattern.	—
23 KD (IgG) Band Shows whether your IgG antibodies react to the 23 kD protein of the Lyme bacterium, one band read as part of a Lyme disease immunoblot pattern.	—
23 KD (IgM) Band Shows whether your IgM antibodies react to the 23 kD protein of the Lyme bacterium, one band read as part of a Lyme disease immunoblot pattern.	—
28 KD (IgG) Band Shows whether your IgG antibodies react to the 28 kD protein of the Lyme bacterium, one band read as part of a Lyme disease immunoblot pattern.	—
30 KD (IgG) Band Shows whether your IgG antibodies react to the 30 kD protein of the Lyme bacterium, one band read as part of a Lyme disease immunoblot pattern.	—

Lyme Disease Antibodies (IgG), Immunoblot The overall interpretation of an IgG Western blot (immunoblot) for Lyme disease, based on the pattern of antibody bands against Borrelia proteins.	—
Lyme Disease Antibodies (IgM), Immunoblot The overall interpretation of an IgM Western blot (immunoblot) for Lyme disease, based on the pattern of antibody bands against Borrelia proteins, used mainly in early infection.	—
