If I am even reading the labwork right. My docs nurse didnt know what that meant which would have meant me waiting on another return call. So , I told her I would figure it out. So here I am...Does anyone know what 1.5 means? Does that make me a type 1 or a type 2? I really wanna know. I have an appt with the endo wednesday and I just don't wanna wait. I tried googling it and I keep having to read all kids of other scary stuff about breast cancer(all that good stuff ties to your c peptide). So if anyone knows- please respond asap- Thanks- Oh and my A1c was 6.6 - Whoo hoo- not too shabby for the slacker job I been doin'

Were you fasting at the time, and if so what was your FBG as shown on those results?

Here's a website that will sort of answer your question: An Old Test Teaches Doctors New Tricks—C-peptide Exam Becoming an Accepted Tool for Diabetes Treatment - Diabetes Health

In there it states this: A consistent display of high blood glucose levels may be sufficient proof of diabetes, but elevated C-peptide levels may reveal if the body has grown resistant to the insulin it is producing. Low or absent C-peptide levels may indicate that insulin production is diminished or non-existent. Anything below the normal range of 0.5 to 3.0 ng/ml of blood means that insulin production has slowed down abnormally, and generally indicates type 1 diabetes. Type 2s, on the other hand, will often yield C-peptide results in the normal range, meaning their fluctuating blood sugars must be due to insulin resistance, rather than decreased production.

I saw once, a chart that showed the criteria for c-peptide/fbg levels to accurately diagnose Types 1, 1.5, or 2. I can't seem to find that one again, I'll keep looking.

Dumplin,
From what I've read, the c-peptide is interpreted differently for different conditions and no range is given for normal, type 1, etc. It depends on age, gender and other factors so it isn't easy to determine what the results mean out of context. The article I read (C-peptide: The Test)
even said different labs have different ranges. Nothing is ever simple.

Based on your a1cs it looks like you spent a fair amount of time running high. Therefore, it may just mean that you're a type 2 that's progressing quickly.

Or you could be LADA or MODY.

You're not plain old type 1, likely.

ok what are all these abbreviations? lol and I agree with you, at this point, after all I have read, I do beleive I am a Type2 therefore I am a candidate for Byetta and not only insulin.

Maturity onset diabetes of the young (MODY)

cool acronyms, eh?

What is the range given on your labwork for that test? Every lab has a different range.

ok- silly me left it at home- but i think it said .5-3.0 - which to me means i am normal?

[BlueSky]

That is a big range. It makes interpretation a bit difficult. A normal fasting c-peptide range I saw was 0.8 - 1.8. But your test result falls comfortably in that range too . A T2 in the early stages would usually have a high or high-normal c-peptide, as the pancreas produces extra insulin to overcome insulin resistance. This long after onset and without insulin treatment, a T1 would probably have a low or low-normal c-peptide. I guess you could be T1.5 . Let us know what your doctor has to say about it.

Was a GAD antibody test performed? This result could also give a clearer definition.
