When exposed to an antigen, the body views it as foreign material, and takes steps to neutralize it. Typically, the body accomplishes this by making antibodies, which are intended to defend the body from invasion by potentially dangerous substances. Several medical tests can be used to test ...

Serological tests determine yourserostatus: whether or not you have detectable antibodies against a particular antigen. Yourserodiagnosiscan beseropositive(your serum tests positive for detectable antibodies against the antigen) orseronegative(your serum tests negative for detectable antibodies against the s...
tests were used to limit Covid's spread rather than to diagnose patients. Such tests are extremely accurate in detecting those who are infectious, as opposed to those who have small amounts of the virus, he said; therefore, antigen tests are a useful tool in stopping the spread of...
ANTIGEN TESTS A newer type of test looks for proteins found on the surface of the coronavirus, rather than the virus itself. These antigen tests are just hitting the market, and experts hope they'll help expand testing and speed up results. ...

Once produced, monoclonal antibodies can be used in screening tests. For example, a doctor testing for drugs or the presence of a disease could expose a patient's blood sample to monoclonal antibodies which will react with the antigen in question if it is present, alerting the doctor to the...
Most rapid tests, as well as self-testing kits you can buy in stores, are antibody tests, which mean they are not looking for the HIV in your body, but the immune response your body produces to HIV, which are known as antibodies. Antigen/antibody tests detect the p24 antigen, one of...
What are antibodies? When your body is exposed to an antigen — or outside substance including viruses, bacteria, and certain chemicals — it causes the immune system to attack it. As part of the response, white blood cells create a certain kind of protein called antibodies. These proteins ...
