The main concept is that infants are best sampled with a heel stick from the plantar surface of the heel. The heel portion of the plantar surface, specifically the medial or lateral aspects, is the safest and most practical site for capillary blood collection in infants. It provides reliable blood flow without risking damage to fragile bones or major structures.

Fingertips are too small and highly sensitive in newborns, making punctures painful and less safe. The back of the knee and the outer ear are not suitable for routine newborn blood sampling due to difficulty of access, higher risk of injury to deeper structures, and poor sample reliability.
