When is it appropriate to use heel puncture for blood collection?

Heel puncture is a standard procedure primarily used for infants, particularly those under six months old. This technique is suitable for infants because their veins are small and fragile, making venipuncture (collecting blood from a vein) more challenging and potentially traumatic. The heel is a good alternative since it is easy to access and allows for the collection of sufficient blood for necessary tests while minimizing discomfort.

Using heel puncture for older children or adults is not advisable due to anatomical differences and the larger size of veins in these populations. In instances where blood is needed from infants, heel puncture is a safe and effective method. It’s important to adhere to recommended practices for blood collection in this age group to ensure both the safety of the infant and the accuracy of the test results.
