Fasting, timing, sample type, and what to bring
Fasting
Fasting requirements may vary by collection lab, so it's important to confirm this ahead of time.
Best time to collect
It's best to schedule your test at a time when you can relax and avoid any stress, as this may affect the results.
Sample type
Blood draw. The collector will explain the process before starting.
What to bring
- Your printed lab order or requisition form — the ordering physician prepares it for you after you order, and you print it (or fax it from your account) before visiting
- Your order confirmation email, in case the collection site asks to see it
- A short-sleeved or loose-sleeved shirt for an easy blood draw
- Water to drink before the draw and a light snack for afterward, if your test requires fasting
- A government-issued photo ID (most collection sites verify identity at check-in)
- A written list of the medications and supplements you currently take
You do not need an insurance card or a payment method at the collection site: the lab does not bill insurance, and you pay at order time, so there is no copay or deductible. The lab also provides the physician's requisition, so you do not need a separate doctor's referral.
Order process and what-to-bring details reflect the lab's published instructions, paraphrased in our own words. Confirm final requirements with the collection lab that will perform your draw.
What the collection involves
A healthcare professional will draw a blood sample from your arm. The process typically takes just a few minutes.
Details worth confirming with the collection lab before your visit:
- Ask if fasting is required before the test.
- Confirm the location of the blood draw.
- Verify what to bring on the day of the test.
When this test is useful
