What is the clinical and laboratory standards institute CLSI recommended maximum depth of heel puncture?

The Clinical and Laboratory Standards Institute (CLSI) recommends a maximum depth of heel puncture not to exceed 2.0 mm. This guideline is aimed at minimizing the risk of injury to the underlying structures, such as bones and nerves, especially in neonates and infants. Proper technique and adherence to this depth are crucial for safe and effective blood sample collection from the heel.
