>> FAQ
Q1. What Size Needle is Used for Blood Draws?
A: Unlike standard measurement systems, gauge numbers and needle size have an inverse relationship. The needle width narrows as the gauge number increases. The most widely used needles in the medical industry range from number 7, the largest, to number 33, the smallest. The most widely used needles for venipuncture are 21-gauge needles, while 16-gauge needles are commonly used for blood donation because they are thick enough to allow red blood cells to pass through the needle without being broken.
