Borrelia Burgdorferi IgM Antibodies

What is the Lyme Disease IgM test?

This test detects IgM antibodies to Borrelia burgdorferi, the bacterium that causes Lyme disease, which is transmitted through tick bites.


Why is this test done?

It helps diagnose early Lyme disease, typically within the first few weeks after exposure when symptoms like fever, fatigue, and rash may occur.


How is the test performed?

A blood sample is analyzed using ELISA and confirmed by Western blot to detect Borrelia-specific IgM antibodies.


What do the results mean?

A positive IgM result indicates recent infection, though false positives are possible. Results must be interpreted alongside symptoms and other test results.


Are there any precautions or preparations required?

No special preparation is required.
