lancet depth setting
The adjustable penetration depth of automated lancets used for newborn blood collection.
Full Definition
Lancet depth setting refers to the adjustable penetration depth of spring-loaded or automated lancets used in newborn screening blood collection. Proper depth setting (typically 2.0-2.4mm for term infants) ensures adequate blood flow while minimizing risk of bone injury or excessive trauma. Settings must be adjusted based on infant size, gestational age, and heel thickness.
Usage
Usage note: Depth is typically measured in millimeters with specific ranges for different populations.
