Diagnostic Test

Definition: A procedure to provide information about a person's condition that helps health care providers to make a diagnosis. Diagnostic tests provide information about whether a person does or does not have a particular disease.

Example: For example, diagnostic tests include chemical analyses of a body substance (such as blood, urine, or saliva), imaging (such as an X-ray or ultrasound), electrocardiograms (to monitor heart conditions), and biopsies (looking at cells under a microscope). Hearing tests and vision tests are other examples of diagnostic tests.
