Fasting, timing, sample type, and what to bring
Fasting
Fasting requirements can vary by collection lab, so confirm with them if fasting is necessary before your test.
Best time to collect
The timing of the test may depend on the lab's schedule; it's best to check with them for the optimal collection time.
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.
