Antibody Serology Tests

What are antibody serology tests? Antibody serology tests are tests that measure the amount of antibodies in a person's serum or plasma. Antibodies are proteins produced by the body in response to foreign substances, such as viruses or bacteria, that are recognized as being harmful by the body. The body produces antibodies to fight the infection. Antibody serology tests identify these antibodies in someone's blood and measure their levels.

Preparation for Antibody Serology Tests No special preparation is required for antibody serology tests. The blood is typically drawn from the arm, using a small needle and vial. You may experience some light bruising, discomfort, or slight bleeding after the test is conducted.

Procedure for Antibody Serology Tests The procedure for antibody serology tests involves drawing a sample of blood from the patient. The sample is then analyzed in a laboratory to detect the presence and levels of antibody proteins. The results of the test indicate whether or not an infection has occurred.

Types of Antibody Serology Tests Some of the most common types of antibody serology tests include:

ELISA (Enzyme-linked Immunosorbent Assay) tests
Western blot tests
Rapid immunoassays
IgG titers
IgM titers

Risks of Antibody Serology Tests The risks associated with antibody serology tests are minimal and typically include bruising and discomfort at the injection site. Most people experience only minor pain when the needle is inserted into the arm.

Why are antibody serology tests done? Antibody serology tests are done to diagnose and monitor infections. They can also be used to determine the effectiveness of treatments for a variety of infectious diseases.

When are antibody serology tests ordered? Antibody serology tests are typically ordered when someone exhibits signs or symptoms of an infection, or when a healthcare professional suspects an infection is present. The tests may also be ordered when a person is exposed to an infectious disease and the healthcare provider wants to monitor the response to the exposure.
