Diagnostic Testing
Diagnostic testing is the process of using clinical tests to determine the cause of a disease. A diagnostic test is used to rule a disease in or out. Any medical test a patient undergoes is considered part of diagnostic testing.
Some examples of diagnostic tests:
Bloodwork (CBC, Chemistry, etc.)
Radiographs (X-rays)
Ultrasound
Glucose Levels Check
MRI
CT Scan
Urine Test
Infectious Disease Tests
Heartworm Test
Brucellosis Test
Pregnancy Test
COVID Test
And many more!
Why is diagnostic testing important?
Diagnostic testing is important to determine what is causing a disease in a patient. Once we have a diagnosis, we can begin the process of treating the patient.
Sometimes when we run a diagnostic test, it comes back showing the patient does not have the disease we were testing for. This is still invaluable as in many cases we need to rule out specific diseases in order to determine what the actual underlying disease is.
