Description
Why It’s Done:
The Lyme Disease (Borrelia burgdorferi IgG) – EIA Test is typically performed to:
• Diagnose Lyme disease: The test helps confirm if a person has been exposed to Borrelia burgdorferi, the bacterium responsible for Lyme disease. It’s used when a person exhibits symptoms that suggest Lyme disease and has a history of tick exposure.
• Assess the stage of the disease: Detection of IgG antibodies suggests that the infection has progressed to a chronic or later stage, as IgG antibodies typically develop several weeks after exposure to the bacteria.
• Confirm previous infection: The test can also be used to determine if someone has had a previous infection with Borrelia burgdorferi, even if they are not currently exhibiting symptoms.
• Differentiate between acute and chronic Lyme disease: Since IgM antibodies typically appear earlier in the course of the infection and IgG antibodies develop later, the ratio of IgM to IgG can provide insight into whether the infection is acute or chronic.
Preparation:
• Fasting: Typically, no fasting is required before the Lyme Disease IgG EIA test.
• Blood sample collection: A blood sample will be drawn from a vein in your arm to detect the presence of IgG antibodies.
• Inform your healthcare provider about any recent symptoms you are experiencing, particularly if you have been exposed to ticks or have been in areas where Lyme disease is common.
• Medications: Inform your healthcare provider about any medications you are taking, especially if you are on antibiotics. Antibiotics can interfere with the test results if taken before or during the acute phase of the infection.
• Timing: Since IgG antibodies develop several weeks after infection, the test is more accurate when performed after symptoms have been present for at least 2–4 weeks.
