An antibody test, also known as serology test, is a blood test used to detect the presence of antibodies in a person’s system. Antibodies are proteins produced by the immune system in response to a foreign substance, such as a virus, bacterium, or toxin, that enters the body. The purpose of the antibody test is to determine whether a person has been previously exposed to a specific disease and has developed immunity to it.

There are two types of antibody tests: qualitative and quantitative. A qualitative antibody test simply determines whether or not antibodies are present in a person’s system, while a quantitative antibody test measures the exact amount of antibodies present in the blood.

Antibody tests are commonly used for the detection of infectious diseases, such as COVID-19, HIV, and hepatitis B and C. They can also be used to determine if a person has developed immunity to a specific disease after vaccination.

It’s important to note that while a positive antibody test result can indicate that a person has been previously exposed to a disease and has developed immunity, it does not guarantee complete protection against future infections. In addition, the presence of antibodies does not always correlate with the presence of active infection. For a definitive diagnosis of a disease, additional tests, such as a viral PCR test, may be required.
