Proinsulin
Order a proinsulin blood test to help evaluate if your body has a problem making insulin or is resistant to the insulin you make.
Proinsulin is a building block used by your body to make insulin as it turns the food you eat into energy. Testing the level of proinsulin in your blood can help evaluate if your body has a problem making insulin or is resistant to the insulin you make. These conditions can increase your risk for developing diabetes or indicate a problem with your pancreas working properly.
