Patient guide

Preparing for your test

A little preparation helps us give you accurate results the first time. If your doctor or our staff gave you different instructions, follow those.

Before you visit

A quick checklist

These apply to most visits, whatever test you are having.

  • Bring your prescription and any previous reports.
  • Bring a list of the medicines you take, and tell us if you take blood thinners.
  • Wear a short- or loose-sleeved top if you are giving a blood sample.
  • Drink water as usual unless you have been told not to. It makes blood collection easier.
  • Not sure whether you need to fast? Call the hotline before you come.
