What is the difference between a diagnostic test and a screening one?
Even though we use the same state-of-the art technology, screening tests differ from diagnostic ones in the fact that a screening test is trying to differentiate the normal from the abnormal non-symptomatic patient. Screening tests do not typically get into detail about pathology, while diagnostic tests do. Furthermore, screening tests are inexpensive, and non-invasive while diagnostic tests are very expensive and often times invasive.
