How to take your sample

Step 1

Wash your hands in warm, soapy water and dry them thoroughly. Warm hands will make it easier to collect your blood sample. You could even have a warm shower first.

Here are some additional tips to help you collect your sample:

  • It is important to drink plenty of water before taking your sample
  • The best location for collecting your blood is from your ring finger or baby finger on the hand that you don’t write with
  • If you have hard skin on your fingers, soaking them in a bowl of warm water first can help to soften your skin
  • It might be a good idea to ask someone to help you take your sample; they could hold the blood collection tube or help massage your arm and hand. If there is nobody around, you could place the tube in the foam insert inside the box your test came in to keep it still Before taking your sample, drop your arm down by your side so your blood will run to your fingertips
  • If you are finding one hand isn’t working very well for you, switch hands as your other hand might have better blood flow, make sure you use a new lancet to prick your skin though


    Step 2

    Using the pre-injection swab provided, clean your finger and then dry it with a clean tissue.


    Step 3

    Remove one of the lancets from the bag in your box, twist and remove the blue stick from the bottom of the lancet. The lancet is now ready to use.


    Step 4

    Make sure you stand up while collecting the blood sample. Position the lancet against the tip of your finger and press down firmly.  If you need to repeat this step, it is important to use a new lancet.


    Step 5

    After piercing your skin, a small drop of blood will form. Wipe away the first drop of blood with a clean tissue.


    Step 6

    Hold your hand and arm downwards and massage from your elbow to your hand and fingers to help form a new drop of blood. Do not squeeze the tip of your finger or the blood will clot, and this will stop it from coming out of your finger. If the drop of blood is not falling quickly, you can lightly tap the droplet against the inside of the tube, and it should drop into the tube quickly.


    Step 7

    Please fill the blood tube to at least the upper line. We need as much blood as possible. If you need to, you can use a new lancet or another finger. Then place the plaster on your finger.


    Step 8

    Place the lid on the tube, and gently invert it 5-10 times.


    Step 9

    Please ensure that you have filled in the inner lid sticker. Then place the tube into the bio-hazard bag and place the bio-hazard bag into the white box - both provided. Then, return the sample to the lab using the pre-paid envelope provided.
