What Does a Positive Antibody Test Mean?
A positive antibody test result indicates that a person has been exposed to a particular virus or bacteria and has developed antibodies to fight it. Antibodies are proteins produced by the immune system to help fight off infection. The presence of antibodies in the blood can indicate that a person has had a previous infection, even if they do not have any current symptoms.
What Are the Different Types of Antibody Tests?
There are several different types of antibody tests available. In general, antibody tests measure the presence of IgG antibodies, which are produced by the body in response to a previous infection. Some tests may also measure IgM antibodies, which are produced by the body during an active infection.
What Happens After a Positive Antibody Test?
If a person tests positive for antibodies, it is important to discuss the results with their healthcare provider. Depending on the type of antibody test and the person's medical history, their healthcare provider may recommend additional testing or other steps to monitor the person's health. It is also important to remember that a positive antibody test does not necessarily mean a person is immune to the virus or bacteria in question.
