BEFORE THE NEXT CONVERSATION
Bring the context.
Use these preparation notes alongside your own clinician’s instructions. They do not interpret a laboratory result or suggest a dose.
Preparation note 1 of 3

- Note when the sample was collected and whether anything in your routine had changed.
- Ask what question this test answers and which results your clinician is comparing.
