Fasting, timing, sample type, and what to bring

Fasting

Fasting requirements can vary by collection lab, so it's important to check with them beforehand.

Best time to collect

The timing of the test can depend on the lab's schedule, so confirm the best time for your appointment with the collection lab.

Sample type

Blood draw. The collector will explain the process before starting.

What to bring

  • Your order confirmation email, in case the collection site asks to see it
  • 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
  • A written list of the medications and supplements you currently take
  • 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)

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.

  • If there are any specific preparation instructions
  • What to expect during the blood collection process
