Measurement

What is a U-100 syringe?

An insulin syringe marked 0 to 100 units. One unit equals 0.01 mL.

A U-100 syringe is an insulin syringe marked from 0 to 100 units. On this scale, one unit equals 0.01 mL, so 100 units make up 1 mL.

It comes up often because many people measure reconstituted peptides in units on these syringes rather than in milliliters. The units on the barrel are a volume marking, separate from IU, which measures activity.

TRKD+ explains what the markings mean so the numbers make sense. It does not tell you how many units to draw. That is a conversation for a licensed provider.

Common questions

How many mL is one unit on a U-100 syringe?
One unit equals 0.01 mL, so 100 units equal 1 mL.
Are syringe units the same as IU?
No. Units on a U-100 syringe mark volume; IU measures biological activity.
