The more you know about your health, the better prepared you are to make informed healthcare decisions. Our health library gives you the information you need to take charge of your health.

The purpose of screening is early diagnosis and treatment. Screening tests are usually administered to people without symptoms, but who may be at high risk for certain diseases or conditions.

There are no screening tests for colds and influenza. Diagnosis and treatment begin with the onset of symptoms.
