The most appropriate site for obtaining a blood sample from infants is the plantar surface of the heel. This area has a robust capillary network close to the surface, allowing a small, shallow puncture with a lancet to yield an adequate sample without penetrating too deep. Target the medial or lateral plantar surface and avoid the center or posterior edge to reduce the risk of hitting bone or tendons. This placement is preferred over other sites because the fingertip, ear lobe, or back of the hand in very young infants often provide less reliable blood flow, smaller vessels, or higher risk of tissue damage and complication. With careful technique and a shallow puncture, the heel site provides a practical balance of safety, accessibility, and sample quality for infant testing.
