There is a multitude of tests that are performed in laboratories and medical clinics to diagnose a condition or disease, this is referred to as diagnostic testing. Specimens for tests may be gathered via blood, urine, tissue, or feces, which is dependent on what type of diagnostic testing is being completed.
X-ray imaging and scans are also considered diagnostic testing and often are chosen after auto accidents occur to assess for damage to the musculoskeletal or neurological systems.
There may be several diagnostic tests completed to confirm or deny a diagnosis. Once diagnosed, testing can also play the role of monitoring the condition or disease. For instance, an injury sustained from a work-related accident can be diagnosed via X-Ray for a broken bone and monitored for healing throughout the care of the injury.
