Insulin syringes are calibrated in what units of measurement?

Insulin syringes are specifically designed to deliver insulin, and their calibration is based on the units of insulin, which are defined by the International Unit (IU) system rather than volume or weight measurements. The standard concentration for insulin is 100 units per milliliter, commonly referred to as U-100 insulin. The unit calibration allows healthcare providers to accurately measure and administer the precise amount of insulin required for patient care, which is critical in managing diabetes effectively. Using units ensures consistency and safety in dosing, as insulin's potency and effect are directly tied to these specific measurements rather than volume or weight.
