In your finger prick blood test kits
Alcohol prep, 2 lancets, bandage, gauze pad, collection card, blood sample return bag, and return mailer envelope (with a test requisition form inside. Do not remove this form).
Note: You will have a spare kit if you need it. If you do not need it, please do not throw this kit away until you have received your results.
Keep in mind before you start
- Keep others from coming into contact with your blood.
- Keep out of reach of children.
- If you feel faint or dizzy, sit down. If you feel ill, contact your doctor.
1: Prepare for your blood test
- Drink 1-2 glasses of water the night before and 1-2 glasses of water 30 minutes before your finger prick blood test. Being well hydrated helps your blood flow and makes the test easier.
- Keep warm before and during the test. This increases blood circulation, making it easier for you to collect.
- Soak your hands under hot water, ensuring they are completely submerged, for at least two minutes.
- Wash your hands thoroughly with plenty of soap. Wash all the soap away with clean, hot water for at least 30 seconds.
- Get blood flowing in your body by swirling your arms around.
Do not use hand sanitizer or any creams or lotions (such as shaving cream or hair gel) before collecting your sample as this will affect the blood quality. If you have used any of these, please wash your hands thoroughly with soap and water.
2: Prick your finger
- Place the contents of your kit on a clean, dry surface.
- Select a finger. We recommend you use one of your three middle fingers.
- Use the alcohol prep pad to clean the tip of the finger and allow the finger to air dry.
- Take a lancet and twist the cap off from the tip.
- Hold the lancet horizontally on your fingertip to the left or right of the center.
- Press the lancet firmly against the fleshy part of the fingertip, until you hear a 'click' sound. You'll see a growing drop of blood form at the fingertip.
Please note: Each lancet can only be used once.
3: Apply blood drops
- To help blood flow, lightly massage your finger downward, starting from the base and stopping when you reach the first knuckle. Be gentle and take care not to squeeze — squeezing will damage your blood cells, causing the test to not be analyzable.
- Use the gauze to wipe the first drop of blood away.
- Lightly massage your finger again, using the same technique, until the next drop of blood appears.
- Let this droplet fall freely into the small square on your collection card. Do not dab your finger on the card.
- Check the exact time you let the first blood droplet land on the card. Remember this for later as you will log it in your app.
- Continue to let blood droplets fall freely into this square until the blood has reached the specified line of the rectangle. This usually takes 4-5 large drops of blood. Be patient and let the drops flow freely; it may take awhile.
- Don't place the blood directly within the large rectangle. The droplets from the square will be absorbed and will naturally move into the rectangle.
- Despite what the card says, it is ok if the blood does not reach the black line. As long as the left-hand square is full of blood, it can be analyzed.
- If you’re worried that you’ve got it wrong, please reach out to us using the chat feature in the app.
- Once your card is filled, cover your pricked finger with the gauze or bandage.
If the amount of bleeding is very slow or blood stops completely:
Use the gauze to gently wipe the finger prick site. This may help reopen the site and allow more blood to flow. If this doesn't help, use a second lancet on the other side of your finger.
If the amount of bleeding is very fast and you begin the 'flood' the card:
Don't panic. You can take as much time as you need to complete the test. Grab the gauze that came in your test kit and apply pressure to your finger prick. Keep your arm elevated for a minute or two to reduce blood flow. Once slowed down, you can continue your finger prick blood test.
4. Log your blood test
- Open the app and follow the instructions to log your completed blood test card.
- Take a picture of the completed card.
- Scan the barcode (on the front of the card) so we can match the test with you.
- Confirm the exact time you started applying the first blood drop on your card.
- You’ll notice a date listed on your collection card. Disregard this.
5: Put your completed card in the blood sample return bag, then into its envelope
- Once complete, let the finger prick blood test dry for 30 minutes, then place in the blood sample return bag. Don't remove the items from inside the bag as these are required for proper testing. Each test goes into its own return envelope.
- Seal the return bag and place it in its pre-addressed, prepaid return mailer envelope. There is a requisition form in each return envelope. Do not remove this form.
- Make sure that you put each completed card into the same envelope that it originally came with, since the card’s barcode is paired with the same form.
- Keep at room temperature until ready to mail that day.
6: Returning your finger prick blood tests
- Mail your blood samples after collection with the pre-addressed, prepaid return envelope via US Postal Service (USPS) the same day you've completed them.
