Prior to collection

You'll need to fast (not eat or drink anything besides water) for 8 hours before testing. We recommend you take the test in the morning to reduce the effects of fasting. Please return your sample via delivery carrier on the same day.

To ensure your sample is tested accurately and in a timely manner, please follow these steps for preparing for your collection:

- Before collecting your sample, make sure you have activated your kit code by creating an account at If this is a second or additional test, please activate your kit code to your account by logging in at

- Wash your hands with warm water (as hot as you can stand) to bring blood flow to your finger tips. Even 60 seconds in warm water increases blood flow by up to 60%. 

- Get up and get moving! Even a few minutes of movement can help improve circulation. We usually recommend light walking or going up and down the stairs once. 

Collecting the sample

Now you're ready to collect your sample! Just breathe, you got this. Here are some tips for getting the best possible sample collection: 

- If this is your first collection, we recommend using your index or "ring" finger. This finger is usually less calloused, which will make it easier for the lancet to be effective.

- The lancet should be firmly pressed into the middle-side of the finger. Not in the middle, due to the nerves there and not too close to the side because it's more difficult to produce the amount of blood required there. Please see the picture below. Ideally, avoid choosing a spot that is either too close to the tip of the finger or are too close to the side. 

-  Always discard the first drop of blood onto your kit's alcohol pad without contacting swab to skin. Make sure you don't touch your fingertip to the alcohol pad to avoid contaminating your sample.

- If your blood is not flowing enough to naturally collect the required sample amount, massage where the knuckle of your collection finger and palm meet to increase blood flow

- When possible, avoid squeezing your finger to extract drops of blood, as this can negatively affect the blood sample.

- Let gravity help you! Keep your hand below your chest and point your finger downward toward the collection device, which will help the drops fall into the collection device. 

Acceptable samples

At the end of your test, your sample should look like the first picture on the left:

If your sample does not look like the picture on the left, please chat us via the button on the lower right of your screen, or send an email to

Post collection

After you have dropped the blood in the collection device, leave the sample to dry for 5-10 minutes. Close the lid of the collection device and place it back in the box, and then into the provided return envelope. If the collection device is put directly into the return envelope, it will not be protected in transit and identified properly at the lab.
