DudeMeds editorial. Educational information, not individual medical advice.
Ask before changing your routine.
Confirm timing and preparation requirements with the lab or ordering clinician. Tell them about medicines and supplements.
Do not stop medicines on your own.
Medication changes should come from your clinician, not a general preparation checklist.
Tell the team if preparation did not go to plan.
Let the lab know when you could not follow an instruction. Ask how that affects the next step.
