A recent study measured the amount of intact in insulin vials to find that no vials met standard insulin concentrations.
The main takeaway from the piece for me: "They randomly picked up eighteen 10 ml vials of insulin from two different manufacturers in the US and discovered that the insulin concentration which was intact ranged from 13.9 to 94.2 U/ml, with a mean of 40.2 U/ml. No vial was at the minimum FDA-required standard of 95 U/ml.
Bottom line is your insulin vial may not contain enough insulin."
This really confuses me. We pay a lot of money for insulin...and we can't expect better quality?
