Immunoglobulin IgM


Take advantage of our packages

The Immunoglobulin IgM is included in test packages, which you can buy at a lower price.

Immunoglobulin M ( IgM) is a glycoprotein that consists of five disulfide-linked structural units (a pentamer) held together by a J chain. On the surface of B lymphocytes, however, IgM is found as a monomer and does not express the J chain. IgM is the first immunoglubulin to be made by a fetus and during an immune response, it is the first immunoglobulin to be detected followed by IgG. IgM is the primary antibody against A and B antigens on red blood cells.

Purpose of the test

The Immunoglobulin IgM blood test measures the amount of IgM antibodies in the blood. IgM antibodies are the first immunoglobulins the body produces in response to an exposure to pathogens. They offer short-term protection while the body produces other antibodies. These antibodies are present in the blood and lymph fluid and play a crucial role in the body's immune response against infections.

Who Should Get Tested

Individuals who frequently suffer from infections or exhibit symptoms of immunodeficiency might require this test. Symptoms indicative of low IgM levels include recurrent sinus, throat, and ear infections, respiratory infections like pneumonia and bronchitis, and infections from pathogens that don't typically affect healthy individuals. Additionally, if there's a family history of immunodeficiency or if a healthcare provider suspects an issue with immunoglobulin production, this test might be recommended.

Preparing for the Test
Depending on the type of cholesterol test, you may be required to fast for 9 to 12 hours before the test. This means avoiding all food and drinks except water. Fasting is usually required for a lipid panel, which measures LDL and HDL cholesterol, and triglycerides.
Inform your healthcare provider about any medications you are currently taking, including over-the-counter medications and supplements, as they can affect your test results.
Avoid alcohol consumption for at least 24 hours before the test, as alcohol can raise triglyceride levels.
Avoid heavy exercise for 24 hours before the test, as this can also affect cholesterol and triglyceride levels.
Avoid smoking or using any nicotine products for at least 30 minutes before the test, as they can temporarily increase cholesterol levels.
Follow instructions
Follow any specific instructions provided by your healthcare provider, such as the time of day to take the test or any dietary restrictions.
Interpreting Test Results

The results of the IgM test are compared with standard levels of IgM, IgG, and IgA. Abnormal levels can indicate various conditions, including autoimmune disorders, chronic infections, or certain types of cancer. Low levels of IgM might be due to conditions that reduce protein in the body, complications from diseases like diabetes, or genetic disorders. On the other hand, high levels might indicate autoimmune diseases, chronic infections, or certain cancers. It's essential to consult with a healthcare provider for a comprehensive understanding of the results, as the test alone cannot diagnose conditions.
