Where can I get insulin resistance test and how much does it cost (USA)?

I have no insurance but I'm pretty sure I have hyperinsulinemia. Where can I get an insulin resistance test done for low cost or possibly for free to be diagnosed? How much would it most likely cost just to get the test done in the US? Do free medical clinics offer this test? If I went in to urgent care how much would it most likely cost and would they perform this test for me?
