![]() It is a part of voluntary service provided by the American Society for Clinical Laboratory Science. Serologic testing is the principal means of laboratory diagnosis of Lyme disease. A laboratory scientist will answer your question. Both steps test for the presence of antibodies to Borrelia burgdorferi, the bacterium that causes Lyme disease. This is the process recommended by the Centers for Disease Control & Prevention to test for Lyme, and is the standard for the accurate diagnosis of the disease. It is useful, if there is no answer on your question on the web site. Positive Western blotThe Quest Lyme disease test is a two-step process.

In addition, you can use a special form to ask the question. In "common questions" tab you will find answers on the most common questions. There you will find the most detailed and full information regarding lab tests. Site associated with The American Association for Clinical Chemistry (AACC) for better understanding of tests. Lyme Disease, Borrelia burgdorferi C6 Antigen With Reflex to Western Blot Lab Test Short Info Understanding of Lab Tests Results For more details, see: Recommendations for Test Performance and Interpretation from the Second National Conference on Serologic Diagnosis of Lyme Disease.And complete the checkout process there. Before CDC will recommend new tests, they must be cleared by the Food and Drug Administration (FDA). New tests may be developed as alternatives to one or both steps of the two-step process. Buy LabCorp: 128. Positive IgM results should be disregarded if the patient has been ill for more than 30 days.ĬDC supports the development of new tests The Lyme disease blood test, western blot is used to detect antibodies specific for B burgdorferi. Some tests give results for two types of antibody, IgM and IgG.Infection with other diseases, including some tickborne diseases, or some viral, bacterial, or autoimmune diseases, can result in false positive test results.Antibodies normally persist in the blood for months or even years after the infection is gone therefore, the test cannot be used to determine cure.Antibodies can take several weeks to develop, so patients may test negative if infected only recently.Most Lyme disease tests are designed to detect antibodies made by the body in response to infection.The overall result is positive only when the first test is positive (or equivocal) and the second test is positive (or for some tests equivocal). The sensitivity of a Line blot assay by itself is not sufficient to assess Lyme infection adequately. This is an acceptable alternative for the serologic diagnosis of Lyme disease. Detect and analyze antibodies against specific B burgdorferi proteins. Verify the results using a second FDA-cleared IgG and IgM immunoassays in place of a Western blot (immunoblot) test. Increased specificity reduces cross-reactivity from other spirochetes. If the first step is positive or indeterminate (sometimes called “equivocal”), the second step should be performed. Provides both IgM and IgG Line blot results. If this first step is negative, no further testing is recommended. Both steps are required and can be done using the same blood sample.
