Lyme Disease Screen Blood Test

About the test

The Lyme disease Borrelia IgG and IgM blood test is a serological test used to detect antibodies against the bacterium Borrelia burgdorferi, which is the causative agent of Lyme disease. IgG and IgM are two types of antibodies produced by the immune system in response to an infection.

The test is typically conducted when a person is suspected of having Lyme disease, especially if they have symptoms such as fever, fatigue, headache, muscle and joint aches, and a characteristic skin rash known as erythema migrans. It's essential to conduct the test at the appropriate time since the body takes some time to develop detectable levels of IgG and IgM antibodies after being exposed to the bacteria.

Here's what the results of the Lyme disease Borrelia IgG and IgM blood test may indicate:

1. Negative IgG and IgM: If both IgG and IgM antibodies are negative, it suggests that the person has not been exposed to Borrelia burgdorferi or has not developed detectable antibodies yet. It is important to note that the test might not be accurate during the early stages of infection.

2. Positive IgM and negative IgG: A positive IgM result indicates recent or active infection, as IgM antibodies are typically produced early in the course of the disease. However, false positives can occur, so further testing and clinical evaluation are necessary.

3. Positive IgG and negative IgM: A positive IgG result indicates a past infection, as IgG antibodies take more time to develop than IgM. It suggests that the person has been exposed to Lyme disease at some point in the past.

4. Positive IgG and positive IgM: This combination can indicate an active or recent infection, but it can also indicate a previous infection with ongoing or recurring symptoms. It's important to consider the clinical context and consult with a healthcare professional for appropriate interpretation.

Interpreting Lyme disease test results requires knowledge and expertise, so it's crucial to consult with a healthcare provider who can evaluate the test findings in conjunction with the patient's symptoms and medical history to make an accurate diagnosis. If you suspect you may have Lyme disease or have been exposed to ticks, seek medical attention promptly. Early diagnosis and treatment are essential to prevent complications associated with Lyme disease.
