serological assays

Serological assays are laboratory tests that detect antibodies in a person's blood. These antibodies are produced by the immune system in response to infections or vaccinations. By identifying specific antibodies, these tests can determine if someone has had a previous infection or developed immunity. They are useful for diagnosing illnesses, studying disease prevalence, and understanding immune responses. Serological assays often involve mixing blood samples with special reagents that highlight the presence of particular antibodies, allowing for accurate detection and measurement.
