What Is A Screening Test?
A screening test is different than most medical tests that are performed. Most medical tests are diagnostic and provide the doctor and patient with a definitive result. A diagnostic test shows that the patient either has a type of medical condition or does not have the condition. In a screening test, the result shows only the patient's risk or chance of having the medical condition. Patient's who are at high risk may in fact not have the medical condition. The purpose of the screening test is to allow the patient to decide whether they would like to undergo a definitive diagnostic test.
