Serological Test

A serological test is a type of medical test used to detect antibodies or antigens in a blood sample. It helps determine if a person has been exposed to a specific pathogen, such as a virus or bacteria. By analyzing the proteins in the blood, healthcare providers can identify infections or immune responses. These tests play a crucial role in diagnosing diseases, checking immunity levels, and screening for infections. They are commonly used for conditions like HIV, hepatitis, and more recently, COVID-19. Overall, serological tests provide important information about a person's health status regarding infectious diseases.
