Antibody tests, also known as serology tests, are laboratory tests used to determine if a person has been exposed to a particular pathogen, such as a virus or bacteria, in the past.
What Are Antibodies?
Antibodies, also called immunoglobulins, are proteins produced by the immune system to help defend the body against harmful invaders, such as viruses, bacteria, and toxins.
How Do Antibody Tests Work?
Sample Collection: A small sample of blood is drawn from a vein
Testing Process: The blood sample is then exposed to specific antigens that correspond to the pathogen of interest.
Results: If antibodies are present in the blood, the test will return a positive result.
