Getting ready for the 5 Grain Allergy Test

Preparing for this test is generally simple, but it’s best to check with the testing location for any specific instructions.

  1. Confirm any fasting requirements with the collection lab.
  2. Stay well-hydrated before the test, as this can help with blood draw.
  3. Bring a valid ID and any necessary paperwork.
  4. Avoid strenuous exercise prior to the test, as it may affect results.
  5. Wear clothing with sleeves that can be easily rolled up for the blood draw.

Fasting, timing, sample type, and what to bring

Fasting

Fasting requirements can vary by collection lab, so confirm with them if you need to fast before your test.

Best time to collect

The best time for this test can depend on your schedule and the lab's availability, so check with the collection lab for recommendations.

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
  • 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.

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.

At the collection site

A healthcare professional will draw a blood sample, typically from a vein in your arm. The process usually takes just a few minutes.

Details worth confirming with the collection lab before your visit:
