At-home Capillary Blood Test
Updated this week

How are At-home Capillary Blood Tests taken?

Taking an At-home Capillary Blood Test is easy and convenient. Just follow the simple steps below. Full instructions will be included in your test kit. Please do your test between Monday and Thursday, then post the test on the same day, as our lab is closed on weekends.

Please be aware that the blood test you are purchasing is intended for personal use only and should not be given to another individual. The results of this blood test will be uploaded to your Numan account. Therefore, providing this test to another individual could result in a breach of medical data sharing.

Step 1: Get prepared

Scan the QR code on the box to receive essential instructions and further guidance for your next steps.

You should set aside around 20 minutes first thing in the morning, before you have eaten, to complete the whole process, especially if it’s your first time taking a blood sample at home. We recommend having a normal evening meal the night before, and drinking plenty of water (2 glasses) in the morning ahead of taking your sample. This will ensure the most accurate results and avoid any fainting or dizziness.

Seeing the sight of your own blood can also make some people feel dizzy or faint. If you think this could happen to you, we advise taking the test in a comfortable, safe environment and ask someone to assist you in taking your sample.

To get your blood flowing, go for a brisk walk, do a few jumping jacks, or maybe take a hot bath - whatever works for you.

Step 2: Set up

Set up a clean workspace with your lancets, alcohol wipes, plasters, and other kit contents. Open the vial and stand it upright on a flat surface.

Step 3: Get started

Wash your hands in warm water for four minutes and then dry them completely. This is essential for a successful blood collection.

Wipe your chosen finger (one of the middle three is best) with the alcohol wipe and allow it to air dry.

Step 4: The lancet

Twist off the blue tab from the end of the lancet. Holding your hand around waist level, position the lancer to the side of the fleshy pad of the finger and press firmly. You will hear a click and feel a slight prick.

Step 5: Collecting blood

After you've pierced your fingertip, use a clean tissue to wipe away the first drop of blood. Gently massage down towards the pierced sit to encourage blood flow, guiding the droplets into the vial without scraping. Collect blood to the top line of the vial.

Step 6: Fill it up

If you need more blood, no worries. Wipe the area clean with a tissue and wait a few seconds for more drops to form. If it's still not enough, move onto the ring finger on your dominant hand. Avoid your little finger and thumb.

Step 7: Mixing

With enough blood collected, close the vial by placing the cap back on and pushing until you hear a click. Wipe excess blood from your skin and apply the provided plaster. Now, gently turn the closed vial upside down 10 times.

You do not need to worry if the blood looks like it hasn't mixed.

Step 8: Final steps

Fill in your details on the sticky labels, then attach one around each vial, making sure the barcodes are visible. Place the vial in the specimen bag and seal them closed. Then, safely dispose of the used materials.

Great job! Your kit is ready to be shipped. The sample can now be posted for free via any UK post box.
