Capillary Blood Kit Instructions
Blood samples must be taken between Monday to Thursday and posted the same day.
💡 Tips for a Successful Sample
- Take a hot shower or bath just before collecting your sample to help blood flow.
- Standing whilst taking your blood sample is best, but it can also be done sitting.
- Keep the hand you are sampling from below your waist and your arm straight.
- When collecting blood drops, milk the full length of the finger — not just the tip.
- Asking a friend to assist you can make the process easier.
⚠️ Fainting (Syncope)
Rarely, some people may feel faint when taking their own sample. Warning signs include: sudden clammy sweat, nausea, fast or deep breathing, confusion, light-headedness, blurred vision, or ringing in your ears. If you feel faint at any point, lie down immediately until you feel better.
Step-by-Step Collection Guide

1
Wash your hands with warm water for at least 20 seconds, then unpack the kit on a clean surface.
2
Remove the lid from the collection tube. Place the tube into the cardboard tube holder to keep it steady.

3
Use the alcohol wipe to clean one of your middle fingers, and let it dry completely.

4
Twist the tip of the safety needle to break the seal, then remove the cap.

5
Place the safety needle firmly on your finger and push firmly to activate. The needle activates once only.
6
Wipe away the first drop of blood with a clean, dry tissue.

7
Gently massage the finger from base to tip (a milking motion) to allow drops to fall into the tube.
8
Fill the tube to the upper line (marked 600). We may not be able to test samples below this line.
9
If you cannot collect enough blood, spare needles are included — try another finger (or two).
10
Apply a plaster to your finger, then firmly press the cap onto the tube. Please wipe any blood from the outside of the tube.

11
Gently turn the collection tube upside down 5 times. Place it into the transport bag, fold the top over and seal it.
12
Post your sample straight away — do not delay.
