In this episode you will learn:

- The only acceptable puncture sites for an infant heel stick are the medial and lateral plantar surfaces of the heel.

- Puncturing the center of an infant's heel carries a high risk of injuring the calcaneus bone, potentially causing osteomyelitis.

- Warming the heel for 3-5 minutes prior to puncture is a crucial step to increase blood flow and ensure a viable sample.

- The first drop of blood must be wiped away because it is contaminated with tissue fluid that can invalidate test results.

- Excessive squeezing or 'milking' of the foot can cause hemolysis and specimen contamination, a common reason for sample rejection.
