Immunoglobulin IgM
About Immunoglobulin IgM test
This test is used to determine the level of immunoglobulin IgM in your blood. Following exposure to germs, IgM antibodies are the initial immunoglobulins produced by your body. These antibodies offer temporary protection while your body generates additional antibodies. IgM antibodies can be found in both your blood and lymph fluid, which is responsible for transporting infection-fighting cells throughout your body.
To distinguish between an acute infection and a chronic infection, it is recommended to undergo an IgM immunoglobulin test

Deviation from normal levels indicates the following:
· Elevated levels of serum immunoglobulin in the blood can be attributed to liver disease, connective tissue disorders, as well as acute and chronic infections.

FAQs
How is the sample collected for an Immunoglobulin IgM test?
A blood sample is collected from a vein in your arm using a small needle. Usually, this procedure does not take more than 5 minutes
What are the risks associated with an Immunoglobulin IgM blood test?
This test involves negligible risk. There might be slight soreness or tenderness around the site where the blood is drawn. Rarely, the site can become infected
Are there factors that can affect IgM levels?
IgM levels can be affected by various factors, including age, underlying health conditions such as kidney disease, and specific medications. Therefore, healthcare providers must carefully consider these factors in order to accurately interpret the results
Can IgM levels help diagnose specific infections?
Elevated IgM levels can actually be helpful in diagnosing certain infections. However, it is important to remember that additional tests are usually required to identify the exact pathogen causing the infection
Can the IgM test detect past infections?
No, the IgM serum test is mainly used to indicate recent or ongoing infections, rather than identifying past infections or providing information on long-term immunity
