Good morning, alunke82! I am insulin resistant but my blood sugar levels were high before I started eating low-carb. Now, I'm also taking metformin.
The c-petide test will show if you are still producing insulin and this test would probably determine if you are type 1 or 2.
The only test that will definitively say if you have any problems with blood sugar is the glucose tolerance test. This is the test which lasts two to three hours. They take a blood sample, you drink a very sugary glucose solution and then they test you after one hour, then two hours and sometimes three hours. This is the test which will solve the mystery if you are having blood sugar problems or if you have diabetes.
