what is difference between IgM and IgG for western blot for lyme. positive for IgM but not IgG, what does that mean? tks

Recent infection: Hi. IgM is present only with recent infection. After IgM levels fall away, IgG takes over for ongoing and recurrent exposure to antigen. (The antibodies in this picture are IgG's). I'm glad your doc was on the ball. She/he may have saved you a world of hurt by making the diagnosis promptly. Good luck! ...Read more

Immunoglobulin M (Definition)

There are 5 classes of immune proteins: igg, iga, igm, ige and igd. Igm fights infection. If you produce too little then infections may occur and you have hypogammaglobulinemia. If you have too much you ...Read more

What does it mean that I have a low IgM level?

Low IgM: Low IgM levels in and of themselves are not common, but can occur. If they occur with low IgG levels or with other clinical symptoms the diagnosis can be different. Isolated low IgM can be caused by a variety of factors, and often eventually resolves. See an immunologist for further evaluation to determine the cause. ...Read more

What does it mean to have a low IgM level?

What does it mean to have a low IgM level?

Immune test: The body normally makes immunoglobulins iga, igg, igm, ige and igd. Low or absent IG levels are seen in patients with recurrent infections. A low igm level that is clinically relevant usually occurs in the presence of a low igg and/or IgA level. It is always best to treat a patient, not a number. If a person is otherwise healthy and only has lower igm, usually no worries. ...Read more

What does low level of IgM mean?

What does low level of IgM mean?

Maybe nothing?: Igm is a type of antibody you make to help fight infections. Slightly low igm by itself may not mean anything (i.e., your nature level). If it is very low, or other antibodies are also low (or not functioning), it may be a sign of immune deficiency that can lead to more infections. If you have ?S, see a clinical immunologist. They can help determine if your immune system is functioning properly. ...Read more

What do elevated levels of IgM mean?

Depends: The "normal ranges" for all lab tests include 95% of the "normal" population; thus, 2.5% of people are above the upper limit, and 2.5% are below the lower limit. There's nothing to worry about if your values are a little bit above the normal range, but a very elevated IgM could be a sign of a problem. You need to check with the physician who ordered the tests to interpret your results. ...Read more

What does it mean if IgM and IgA levels drop lower?

What does it mean if IgM and IgA levels drop lower?

IgM and IgA: Low levels of IgA and IgM may mean that you have an immune deficiency. If they are only slightly low and your igg is normal and you are able to respond to vaccines and do not have a lot of infections, there may be nothing to worry about. We need a lot of history and additional blood tests to understand what any particular level of antibodies in the blood means. ...Read more
