In your finger prick blood test kit
Alcohol prep, 2 lancets, bandage, gauze pad, collection card, blood sample return bag, and return mailer envelope (with a test requisition form inside).
Keep in mind:
- Keep others from coming into contact with your blood.
- Keep out of reach of children.
- If you feel faint or dizzy, sit down.
- Each lancet can only be used once.
If the amount of bleeding is very slow or blood stops completely:
Don’t panic. You can take as much time as you need to complete the test. Use the gauze to gently wipe the finger prick site to reopen it and allow more blood to flow. If this doesn’t help, use the second lancet on a different finger and continue.
If the amount of bleeding is very fast and you begin to ‘flood’ the card:
Don’t panic. Grab the gauze and apply pressure to your finger prick site. Keep your arm elevated for 1-2 min to reduce blood flow. Once slowed down, you can continue your test.
Before you begin your test
STEP 1: Drink loads of water. Being well hydrated helps your blood flow and makes the test much easier. We recommend at least 1-2 glasses of water the night before and 1-2 glasses of water 30 minutes before your finger prick blood test.
STEP 2: Keep warm before and during your test. This helps your blood circulation and makes the test easier. Run your hands under hot water for at least 2 minutes before your test. You can also wrap yourself with a warm blanket or have a hot shower before your test.
STEP 3: Get blood flowing in your body by swirling your arms around. A few seconds of light exercise that elevates your heart rate can help.
STEP 4: Place the contents of your kit on a clean, dry surface.
STEP 5: With a pen, write the date of your blood test on the card, ensuring not to touch the specimen area (e.g. 1/30/2021).
STEP 6: Wash your hands thoroughly with plenty of soap and with clean, hot water. Make sure to wash all the soap away and clean your hands of any lotions, gels or sanitizers.
Then soak your hand in hot water for 2 minutes to get blood flowing. Then dry your hands with a clean towel. Do not use hand sanitizer or handle any gels or lotions before collecting a sample as this will affect the test.
Doing your test
STEP 7: Select a finger. We recommend using one of the three middle fingers of your non-dominant hand. Then gently massage your hand towards the end of that finger to encourage blood flow.
STEP 8: Use the alcohol prep pad to clean the tip of the finger and allow the finger to air dry.
STEP 9: Take a lancet and twist the cap off from the tip.
STEP 10: Touch the lancet at the designated spot on your finger.
STEP 11: In a quick motion, press the lancet firmly against the fleshy part of your fingertip, until you hear a ‘click’ sound.
STEP 12: That’s it! You’ll see a growing drop of blood form at the fingertip. Use the gauze to wipe the first drop of blood away as it contains intercellular fluid and should not be used
STEP 13: Lightly massage your hand towards the end of your fingertip, stopping at your first knuckle, until the next drop of blood appears. When massaging your hand, don’t go past the first knuckle as this will damage your blood cells and ruin your test.
STEP 14: Without touching the card with your finger, let this droplet fall freely into the small square on your collection card.
STEP 15: Check the exact time this drop of blood lands in the square. You’ll need to remember this time later to log in the ZOE Test app.
STEP 16: Place 4-5 drops of blood in the square until it’s full but not overfilled.
NOTE: Despite what the card says, it is okay if the blood does not reach the black line. The blood will slowly flow into the rectangle during the 30-minute drying time. Do not place the blood directly within the large rectangle on the right-hand side.
Here’s what the perfect card looks like immediately after completing:
And here’s what to avoid:
Step 17: Once the left square is full, cover your pricked finger with the gauze or bandage and apply pressure. This can help prevent soreness and bruising later.
After your test
STEP 18: While your blood test is drying, log your completed blood test in the ZOE Test app. Open the app, tap on the ‘Do your blood test’ task on your timeline and follow the instructions on screen. First take a picture of the completed card.
STEP 19: Then scan the barcode on the front of the card, and enter the exact time you started applying the first blood drop on your card.
STEP 20: Allow your finger prick blood test to dry for at least 30 minutes. During that time, the blood will slowly flow into the right-hand side rectangle and serum will separate out.
STEP 21: Place the dried blood test card into the blood sample return bag. Do not remove the items from inside the bag as these are required for proper testing.
STEP 22: Remove your requisition form from the return envelope and add the date (e.g. 1/30/2021) and time you completed the blood test. Then put the requisition form back in the envelope.
STEP 23: Seal your blood sample return bag and place it in the return envelope, together with the requisition form. You can keep the envelope at room temperature until you are ready to mail it.
STEP 24: Here’s your final checklist:
Did you add the date on your card?
Did you log your blood test in the Zoe Test App (with time)?
Did you let your card dry for at least 30 minutes?
Did you put the blood sample in the return bag and seal it?
Did you write the date and time on the requisition form in the envelope?
Did you put the blood sample return bag and requisition form back into the envelope?
Great! Seal your envelope and mail it via US Postal Service (USPS) by placing it in your mailbox or dropping in a USPS collection box the same day you’ve completed the test. If the mail is not running that day, it is ok to mail it the following day.
