Tests and diagnosis

By Mayo Clinic Staff

In most cases, your doctor can diagnose pink eye by asking questions about your symptoms and recent health history and performing a physical examination of your eyes.

Rarely, your doctor may also take a sample of the liquid that drains from your eye for laboratory analysis (culture). A culture may be needed if your symptoms are severe or if your doctor suspects a high-risk cause, such as a foreign body in your eye, a serious bacterial infection or a sexually transmitted infection.
