serologic tests

Serologic tests are laboratory analyses that detect specific antibodies or antigens in a person's blood, helping determine if they have been exposed to an infection or immune response. These tests identify the body’s immune response to bacteria, viruses, or other pathogens, providing valuable information for diagnosing illnesses, monitoring immune status, or guiding treatment. They are often used for conditions like COVID-19, HIV, or flu to confirm past or current infections. Results can help healthcare providers understand a person's immune history and decide on appropriate care or vaccination needs.
