Immunoglobulins Blood Test

What is an Immunoglobulins Blood Test?

An immunoglobulins blood test is an immunoassay that measures the different types of antibodies, or immunoglobulins, present in the blood. Immunoglobulins are a type of protein produced by the body's immune system to help fight off infection and disease. The test can be used to diagnose a wide range of autoimmune and other disorders, including allergies, infections, and cancer.

Preparation for an Immunoglobulins Blood Test

Before having an immunoglobulins blood test, you should talk to your doctor about whether you need to make any dietary or lifestyle changes to prepare for the test. Generally, there is no specific preparation required. Fasting is usually not necessary.

Procedure for an Immunoglobulins Blood Test

The procedure for an immunoglobulins blood test is similar to a routine blood test. A health care professional will draw a sample of your blood and send it to a laboratory for testing. Results usually take several days to come back. Your doctor will discuss the results with you.

Types of Immunoglobulins

There are four main types of immunoglobulins, including IgA, IgE, IgG, and IgM. Each type is responsible for different functions in the body, including targeting specific pathogens and helping to fight infection. A doctor may order a test to determine the amount of each type of immunoglobulin present in the bloodstream.

Risks of an Immunoglobulins Blood Test

An immunoglobulins blood test has no known risks associated with it. The only risk associated with this test is mild discomfort or a bruise at the site where the needle was inserted to draw blood.

Why is an Immunoglobulins Blood Test Done?

An immunoglobulins blood test may be ordered by your doctor if they suspect that your body is not producing enough antibodies to fight off infection or if they believe that you have an autoimmune disorder. This test is also used to help diagnose conditions such as allergies, HIV/AIDS, rheumatoid arthritis, and lupus.

When is an Immunoglobulins Blood Test Done?

An immunoglobulins blood test may be ordered if your doctor suspects that you have an immune disorder or an infection. It may also be ordered if you have symptoms of an autoimmune disorder, such as fatigue, joint pain, or a rash.
