I can't draw enough blood to fill the vial

If you are struggling to collect enough blood, try the steps below to improve blood flow.

Before you start

  • Do some light exercise. Swing your arms in circles for a few minutes to increase circulation in your arms and hands.

  • Stay hydrated. Drinking water can make collection easier and may support more accurate readings for biomarkers such as cholesterol and kidney function.

  • Warm up. Take a hot shower or bath, or wash your hands in warm water at around 40°C for at least 4 minutes.

While collecting your sample

  • Stand upright and keep your hand and the vial below waist height so gravity can help.

  • Massage the length of your finger in a steady milking motion.

  • Prick the side of your finger.

  • Shake your hands at waist height before trying again.

  • Try a different finger if needed.

If you are still unable to fill the vial, contact our Customer Care team for help.
