What does a positive IgM band 41 mean?
What does it mean if your 41 KD (IGM) Band result is too high? Two types of antibodies are detected in the Western blot test. This particular marker is called 41 KD (IGM) and hence is a IgM antibody marker. IgM antibodies reflect a relatively recent infection.
Is band 41 Lyme disease?
What is the significance of band 41 on the IgM and IgG Western blot? It is not Lyme specific and the CDC requires more bands to be present before a diagnosis. However, it is a band for bacteria so what else could cause that to be positive if not Lyme? The 41 kd band is often found on the Western blot.
Is band 23 Lyme specific?
Some Lyme specialists and scientists believe that there are five very specific bands on the Western blot test that are highly indicative of Lyme disease: band numbers 23, 31, 34, 39 and 93. If any of these bands are positive and the patient is experiencing symptoms of Lyme disease, they may feel treatment is warranted.
What does a positive IgM indicate?
IgM is usually the first antibody produced by the immune system when a virus attacks. A positive IgM test indicates that you may have been recently infected or vaccinated and your immune system has started responding to the vaccination or that your immune system has started responding to the virus.
How do you detect Lyme disease?
Advertisement
- Enzyme-linked immunosorbent assay (ELISA) test. The test used most often to detect Lyme disease, ELISA detects antibodies to B. burgdorferi.
- Western blot test. If the ELISA test is positive, this test is usually done to confirm the diagnosis.
How long does IgM stay positive Lyme?
IgM or IgG antibody responses to B. burgdorferi may persist for 10-20 years, but these responses are not indicative of active infection.
What does a positive IgM band 23 mean?
Two types of antibodies are detected in the Western blot test. This particular marker is called 23 KD (IGM) and hence is a IgM antibody marker. IgM antibodies reflect a relatively recent infection. IgG antibodies in contrast are a sign of an older infection.
How long is IgM positive in Lyme?
IgM antibodies rise quickly after infection, reaching their peak within 3 weeks but may persist for many months following onset. Therefore, a positive IgM and negative IgG Western Blot should be interpreted with caution.
Does positive IgM mean I have COVID-19?
The presence of IgM suggests that the infection or vaccination happened recently. How much IgM antibodies might protect you from getting sick with COVID-19 in the future is unknown.
What is considered a high IgM level?
In a study of over 9.3k people, higher IgM levels (above 110 mg/dL for men and 150 mg/dL for women) were associated with a higher incidence of metabolic syndrome (elevated triglycerides and lower HDL-C in particular) [48].
