When are Diagnostic Tests typically ordered for a patient?
Answer
When a person already has symptoms or has had an abnormal screening result.
The decision to order a specific diagnostic test usually stems from existing clinical indicators. If a patient presents with noticeable signs or symptoms, or if a prior, broader screening test has yielded an abnormal finding, the provider moves to the focused investigation phase. The purpose of ordering a diagnostic test in these scenarios is no longer broad exploration but a targeted effort to investigate the existing concerns and either confirm or definitively rule out a condition that is already suspected based on the initial presentation.
