In my last labs included a proinsulin test. guidelines are <18.8 and my results were 17.8. I looked it up online and understand what the test is for, but I couldn't find anything on how to interpret the results. From what I saw, they did not run a c-peptide test, just the proinsulin. I do have a message out to my Dr, but it will probably a few days before they get back to me. Has anyone had this test? Can you help me?

Interesting post. I had never heard of either one of these tests. One can learn something new almost every day here on DC.

Update: I spoke with a lab tech today re coming up for another blood draw for the lipid panel. I asked her about the mix up; it WAS my blood used for the test and the results ARE mine. I'm sure my Dr has seen these results by now so if she isn't concerned about it, I'm not going to be either.

When I spoke to my Dr's nurse yesterday, I got the impression that the test wasn't mine. I guess what she meant was my Dr didn't order it. I'm still curios about what the results indicate (for me) though.

You posting about this test may have a silver lining. My 19 year old granddaughter was thinking she has diabetes. But her symptoms were more like hypoglycemia. I suggested a glucose tolerance test, which if I remember takes about 6 hours. This proinsulin test sounds like an easier test. She sees here doc today. I'll update.

Chronic hypoglycemia can be a sign of T2D in the future. I had hypos all my life and would self treat with a coke and candy bar. The result was insulin resistance, weight gain and T2D. I would not wish this on anyone and certainly not my granddaughter.

It was a false alarm! The testing lab substituted a proinsulin test instead of a lipid panel and the results are not even mine. I wondered what was up when I saw the name had been corrected. The lab has offered to run the lipid panel free of charge. A bit relieved over that.

I know what the test is for, I found that info. I suspect my Dr fan it to make sure I'm not hypo. I've been <6 for a long time. What I can't find is how to interpret my results. I hope she doesn't think I have a pancreatic tumor.

It is basicly the same thing as c-peptide Sue.
This blood test measures proinsulin, a building block for insulin. To turn food into energy, your pancreas makes proinsulin. Proinsulin, in turn, is made into insulin and another protein called C-peptide.
It is just the biochemical hormonal process of the body in measurements.
