Serology testing

Serology testing is a blood test that detects antibodies, which are proteins your immune system produces in response to an infection or exposure to a specific germ, such as a virus or bacteria. The test helps determine if you have been previously infected or vaccinated and if your immune system has mounted a response. It can also identify if you have ongoing or past infection, providing valuable information for diagnosis, treatment, and understanding immunity. While it doesn't diagnose active infections directly, it offers insights into your immune history regarding certain diseases.
