How do you take a blood sample from your foot?

Published in Blood Sample Collection 2 mins read

Taking a blood sample from your foot, specifically the heel, involves a few key steps using a capillary collection method. Here's a breakdown:

Heel Prick Procedure

The process, typically used for infants, includes:

  • Preparation: Ensure the heel is clean.
  • Puncture: Use an appropriate device to puncture the heel firmly.
  • Wipe: Relax the pressure on the heel and wipe away the first drop of blood.
  • Collection: Gently compress the heel to form another drop of blood. Without the collection device touching the skin, collect the blood into the capillary.

Step-by-Step Guide

Step Action
1 Clean the heel area thoroughly.
2 Use the appropriate device to quickly puncture the heel.
3 Relax pressure on the heel.
4 Wipe away the initial drop of blood.
5 Gently squeeze the heel to form a new drop of blood.
6 Collect blood into a capillary device without touching the skin.

Key Considerations

  • Device: Use a specialized heel stick device to control depth of the puncture.
  • Capillary Tube: Ensure the collection device, such as a capillary tube, does not touch the skin.
  • Collection technique: It is essential to only compress the heel gently, to avoid excess squeezing that could lead to incorrect test results.

This method ensures a clean and accurate blood sample is obtained from the heel area.
