Serological Testing

Serological testing is a laboratory method used to detect antibodies or antigens in a sample of blood. These antibodies are produced by the immune system in response to infections or vaccines. By analyzing the presence and levels of these substances, healthcare providers can determine if a person has an active infection, has been exposed to a pathogen, or has developed immunity. This type of testing is commonly used for diagnosing diseases like HIV, hepatitis, and various viral infections, and it plays a crucial role in public health and individual patient care.
