  2. Ask the lab whether any fasting or timing instructions apply to your visit.
  3. Bring a valid photo ID and your test order or requisition.
  4. Wear clothing that allows easy access to a vein for a blood draw.

Fasting, timing, sample type, and what to bring

Fasting

Fasting is usually not required for this panel, but requirements can differ by lab. Confirm with your lab.

Best time to collect

There is generally no special timing window for this test. Collect the sample at your scheduled appointment as directed by the lab.

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
  • Any chain-of-custody paperwork the ordering service provided

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.

The collection visit, step by step

A trained phlebotomist collects a blood sample from a vein, usually in your arm, using a small needle. The sample is then sent to the laboratory for analysis.

Details worth confirming with the collection lab before your visit:

  • Which twelve drug classes are included in this panel?
  • Do I need to fast or follow any timing instructions before the draw?
  • How long will it take to receive my results?
