(3) There is an “ambiguous” category for both IgG and IgM blots, indicating that although there are insufficient antibody bands for the blot to be reactive, there is significant immunological activity associated with the Lyme disease can be linked.
How do I read Lyme disease test results?
A positive initial and confirmatory test result means your signs and symptoms are likely caused by Lyme disease. A positive result for IgM antibodies but negative IgG and Western blot results may mean you have a very recent infection, or a positive result if you do not have Lyme disease (false positive). 16
What does ambiguous IgM mean?
Herpes IgM Test Results An equivocal test result means the test was unable to determine whether or not an antibody was present.
What is the normal range for Lyme disease?
Normal values vary as follows depending on the laboratory test performed. Enzyme immunoassay Borrelia burgdorferi antibodies (Lyme index value): 0.9 = negative. 0.911.09 = ambiguous. 20
What is the most accurate test for Lyme disease?
A blood test not only detects Lyme disease, it is also the most accurate and preferred test for diagnosing the disease. If a patient with Lyme disease shows signs that the central nervous system is affected by the disease, a cerebrospinal fluid (CSF) western blot test may be done. 18
What Are the 3 Stages of Lyme Disease?
Although Lyme disease is generally classified into three stages—early localized, early disseminated, and late disseminated—the symptoms can overlap. Some people also develop the disease at a later stage without showing symptoms of an earlier disease.
What does a Lyme flare look like?
a red, expanding rash at the site of the tick bite. Tiredness, chills and general malaise. Itching. Headache.
What is IgM in the blood test?
Immunoglobulin M (IgM): Found mainly in blood and lymph, this is the first antibody the body makes when fighting a new infection. Immunoglobulin E (IgE): Normally present in the blood in small amounts. There can be higher amounts when the body is overreacting to allergens or fighting a parasitic infection.
