Fasting, timing, sample type, and what to bring

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.
