The U-40 1/2cc syringes have marking for 20 units. To give just one unit seems difficult to tell if all the air is out and it is truly one unit that is drawn up. I work in the medical field and typically if you are working within a 1-10unit marking the syringes are smaller and marked with 1/2 units or even 1/4 units. I feel the syringes are too large for drawing up such a small amount. This may be another "standard" that my vet said I would need. Do they make diameter syringes that include 1/2 or 1/4 markings for the U-40 insulin?
Many of us using ProZinc use a conversion table based on the following:
U-100 means 100 units per mL
U-40 means 40 units per mL; this is a 40% lower concentration per mL
If you use a U-100 syringe to dose U-40 insulin, the mark on the U-100 syringe should be multiplied by 0.4 to get the dose of the U-40 insulin actually being given
so:
U-100 syringe mark of 1.0 * 0.40 = 0.4 units of U-40 insulin
U-100 syringe mark of 2.0 * 0.40 = 0.8 units of U-40 insulin
U-100 syringe mark of 3.0 * 0.40 = 1.2 units of U-40 insulin
If the syringe measures half units, you can calculate in 0.2 units of U-40
ie:
U-100 syringe mark of 0.5 * 0.40 = 0.2 units of U-40 insulin
U-100 syringe mark of 1.5 * 0.40 = 0.6 units of U-40 insulin
U-100 syringe mark of 2.5 * 0.40 = 1.0 units of U-40 insulin
I'm using U-100 3/10 cc 5/16" long needle syringes with half unit markings from WalMart .
