How to collect my cassette sample (with video)

Collection Tips

  • Read all instructions in your kit from start to finish before you collect your sample.
  • Make sure your hands are free of any soaps, lotions, or creams before collecting you collect your sample.
  • Choose a clean, dry counter or table in a bright, well-lit area to perform your test.
  • Increase blood flow by firmly wiping the puncture site with the gauze pad between each drop of blood.
  • Let your sample air-dry for 15 minutes before packaging and mailing it your sample within 24 hours of collection.

How To Collect

Warm your hands

It's essential to get your blood flowing before you collect your blood sample. Do this by warming your hands with hot water for at least 1 minute, and then shaking them at your sides for 15-20 seconds.

Choose a finger

Find a spot on the right or left side of your ring finger. Clean the area using the alcohol prep pad and let your finger dry before moving to the next step.

Use lancet

Remove the clear plastic top from the lancet. Place the lancet on a countertop with the red area facing up. When ready, firmly push and hold your finger against the red top to trigger the lancet. Use a gauze pad to wipe the puncture site once, which helps prevent clotting.

Drip blood

With your finger pointed down, gently squeeze from your wrist to the puncture site. This should produce a large "hanging" drop of blood. Place blood drop in the collection well. It will take approximately 4 drops of blood for the indicator window to turn red. Avoid milking or squeezing your finger.

Check cassette and clean up

Repeat until the well is completely filled and the indicator window is red. Apply your bandage and let the device air-dry for 15 minutes. You did it!
