Three things to confirm before a laboratory test or scan
The exact test, the correct preparation and the pathway for reviewing your results.

This article provides general information and cannot replace an individual clinical assessment.
Before a diagnostic test, confirm exactly which test or scan was requested. Similar-sounding tests can have different preparation requirements.
Ask whether you need to fast, drink water, change clothing, bring previous results or follow another specific instruction. Do not stop medication unless a qualified clinician specifically tells you to do so.
Finally, clarify when results are expected and who should interpret them. A result without the clinical context that prompted the test can be misleading.
