Virology:

Virology is where tests for viral and Chlamydial diseases are performed. Tests are designed to detect the virus (antigen detection) or the body's defense to a virus (antibody detection). Some of the frequent tests are for Herpes Simplex Virus (HSV), Hepatitis B antibody tests, Measles (Rubeola) immunity status, and Human Immunodeficiency Virus (HIV) antibody screening (the "AIDS" test).
