How to Collect Your FoodSafe™ Allergy Test Sample

We make it easy for you to collect your FoodSafe™ sample from the comfort of your home. This guide walks you through each step of the blood spot collection process so you can get accurate results without stress.

Before You Begin

A quick checklist to help you start smoothly.

  • Your test kit
  • A completed requisition form
  • Payment (if not already submitted)
Medication note: Check with your healthcare provider about any medications you’re taking, including over-the-counter products, as some may affect your test results. Do not stop or change medications without medical guidance.

Prepare Your FoodSafe™ Sample Tools

Find a flat, clean surface like a table or countertop. Lay out the contents of your kit:

  • Blood spot card
  • Alcohol prep pads
  • Rubber band
  • Lancets
  • Cotton balls
  • Band-aids
  • Biohazard bag
  • Return envelope
Important: Write your name and the date of collection on the blood spot card before you begin.

Tips for Better Blood Flow

For easier collection, try these about an hour before you start:

  • Drink a large glass of water
  • Warm your hands in hot water
  • Swing your arm in a circle or back-and-forth
  • Keep your arm below your heart
  • Stand while collecting the sample

Step-by-Step Collection Instructions

Take your time — a calm pace helps improve sample quality.

  1. Wash your hands in hot, soapy water. Dry thoroughly.
  2. Fill out your requisition form if you haven’t already.
  3. Apply the rubber band to your forearm like a tourniquet. It should be snug.
  4. Choose your puncture site — off-center on your middle or ring finger.
  5. Wipe the site with an alcohol pad and let it dry.
  6. Twist the cap off a lancet, press it firmly on your finger, and puncture the skin.
  7. Milk your finger gently to form a droplet of blood. Don’t squeeze too hard or continuously.
  8. Let a large droplet hang, then touch it to one of the circles on the card — without letting your finger touch the card.
  9. Fill all five circles completely. You may need to use a second lancet and finger.
Sample quality tip: The blood should soak through to the back of the card.

After Collection

  • Use a cotton ball to stop the bleeding and apply a bandage if needed.
  • Let the blood spot card air dry overnight. Do not expose it to sunlight, heat, or humidity.
  • Once dry, fold the cover over the blood spots.
  • Place the card and your requisition form in the biohazard bag, then into the return envelope.
  • Seal and mail.
Mailing note: No postage is required if you’re mailing within the U.S.
