Lyme Disease (Borrelia Burgdorferi IgG) - ELISA

ELISA stands for Enzyme-Linked Immunosorbent Assay. It's a commonly used method for detecting the presence of antibodies in the blood.

The ELISA test for Lyme disease has a high sensitivity and specificity, making it an effective screening tool for Lyme disease. However, it's possible to have false-positive or false-negative results, which is why additional testing is often required to confirm the diagnosis.

IgM antibodies are typically produced early in an infection, whereas IgG antibodies are produced later and remain in the body long term. Testing for both types of antibodies can provide information about the timing of the infection.

The test might be repeated if initial results are negative but symptoms of Lyme disease persist. As it takes some time for the body to produce detectable levels of antibodies, testing too early in the infection may result in a false-negative result.

No, this test cannot be used to monitor treatment progress. The IgG antibodies remain in the body for a long time, so their presence doesn't necessarily reflect current disease activity.

Other tests that might be ordered include the Western Blot test, which can help confirm the diagnosis, and tests for other tick-borne diseases, which can produce similar symptoms.

Lyme disease is typically treated with antibiotics. Early treatment is crucial to prevent more serious complications from developing.

Prevention strategies include avoiding areas known to have high tick populations, using insect repellent, performing regular tick checks after being outdoors, and removing any attached ticks promptly and properly.

False positives can occur in people with other bacterial infections or with autoimmune diseases, as these conditions may trigger the production of antibodies that cross-react with the Borrelia burgdorferi antigens used in the test.

The test is performed on a blood sample. The sample is mixed with a specific antigen (a substance that triggers an immune response), in this case, Borrelia burgdorferi antigen. If IgG antibodies against this bacterium are present, they will bind to the antigen. Then, an enzyme is added that causes a color change if the specific antibodies are present, indicating a positive result.

No, Lyme disease is not contagious and cannot be transmitted from person to person. The disease is primarily transmitted to humans through the bite of infected black-legged ticks, also known as deer ticks.

Yes, it's possible to get infected with Lyme disease more than once. Previous infection with Borrelia burgdorferi does not provide lifelong immunity, and individuals can get re-infected if bitten by another infected tick.

Yes, it is possible. This test detects the body's immune response (IgG antibodies) to the bacteria, not the bacteria itself. Because it can take a few weeks for these antibodies to reach detectable levels, the test may be negative in the early stages of infection. If Lyme disease is strongly suspected, the test may need to be repeated or other tests may be performed.

In some cases, a person may not produce enough antibodies to be detected by the test, especially if the test is done too early in the course of the infection. Also, individuals with compromised immune systems may not mount a strong enough response. Finally, treatment with antibiotics early in the course of the disease may prevent or lower antibody production.

Yes, the ELISA test is a versatile method that can be used to detect antibodies or antigens for many different diseases, not just Lyme disease. The specific disease being tested for depends on the particular antigen used in the test.

As of my knowledge cutoff in September 2021, there is no human vaccine for Lyme disease available in the United States. Vaccine development is a rapidly evolving field, so it's recommended to consult with a healthcare provider for the most recent information.

This test is quite safe and carries minimal risks, similar to those of a routine blood test. These can include slight pain or bruising at the injection site or fainting during blood draw. The benefits of diagnosis and subsequent treatment far outweigh these minor risks.

Certain medications may interfere with the test results. Therefore, it is important to inform your healthcare provider about all the medications and supplements you are currently taking.
