Fasting, timing, sample type, and what to bring
Fasting
Fasting requirements can vary by collection lab, so it's important to confirm with them whether fasting is necessary for this test.
Best time to collect
The best time for the test may depend on the lab's schedule; confirm the timing when you make your appointment.
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
- 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
- A short-sleeved or loose-sleeved shirt for an easy blood draw
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 happens during the collection visit
A healthcare professional will draw a blood sample, usually from a vein in your arm. The sample will then be sent to a laboratory for analysis.
Details worth confirming with the collection lab before your visit:
- Whether fasting is required
- What identification or documents to bring
- Any specific instructions for the day of the test
