The Unscripted PharmacistStep 2
Get your fasting insulin blood test.
One blood draw. Ask for a fasting insulin and an A1C together. In most states you can order both yourself, with no doctor's visit.
No lab company pays me to list them.
Order it yourself

Sells fasting insulin and A1C. Blood draws happen at Labcorp.
Blood draws are not available in New York, New Jersey, Rhode Island, Maryland or Massachusetts. Use Quest there.
Quest
Fasting insulin is part of Quest's "Insulin Resistance Test Panel." The A1C is sold on its own as "Hemoglobin A1c Test." Buy both for one draw.
No doctor's visit needed. Quest says an independent healthcare provider reviews the results.
Not available in Arizona (use Sonora Quest), Hawaii or Puerto Rico.
Labcorp OnDemand
Sells the A1C. Its "Insulin Resistance Test" is a different score and does not report a fasting insulin, so get the insulin from Own Your Labs or Quest.
Fast the way the lab company tells you to before the draw. State rules and products change. This list is as of October 2026. Check at checkout, and if one company doesn't serve your state, try the next one.

Want the full picture? The Kraft test
The orange is the insulin shadow. Glucose looks normal. Insulin is working hard to keep it there.
Kraft found many people with normal glucose and high insulin. That's insulin resistance in broad daylight.
In 1996, an American Diabetes Association task force found that the same blood sample gave "widely disparate" insulin results from lab to lab. Insulin is still not part of the ADA's diagnostic criteria. The ADA's stated mission is "to prevent and cure diabetes and to improve the lives of all people affected by diabetes."
This test is a sugar drink with insulin and glucose drawn over several hours. It needs a doctor's order. Quest lists it as "Insulin Response to Glucose." Labcorp lists "Insulin, Five Specimens."
