C-peptide test

I was wondering if anyone could help me analyse my c-peptide results, please.
I had a non-fasting test recently with a result of 1029 with blood glucose of 7.6.
I have no idea what this means, other than I think I must be producing insulin?
Does this mean I'm now likey to be Type 2 and definitely not Type 1?
The test is to be repeated in 6 months time.
The result doesn't mean anything to me.....1029 what? And I can't seem to
find what a normal reading should be.
I've been on 20-30ml of Novomix per day, plus Metformin, since June 2013.
Any comments would be gratefully received!
 
Hi. I'm going to guess a bit here and perhaps someone else can comment? My results which I had done privately by MediChecks were:

1.19 ug/l with a range of 1.1 to 4.4 That impied that my c-peptide was low and that I have low insulin. I wonder whether your reading could be interpreted as 1.029? I'm just guessing and the units my report used of ug/l were also a bit unusual. My c-peptide test was fasting and views seem to vary on whether it should be done fasting or non-fasting.
 
Thank you, Diabell. I also thought there could be a missing point in the 1029, but I don't understand why there were no units mentioned. I think the letter was suggesting that this reading was at the higher end of the scale, as the letter mentions considering a trial without insulin therapy, depending on the results of the repeat test. I guess my best move would be a chat to my GP for some clarification. In the meantime, I would still be interested in any other comments.
Thanks again for your reply - much appreciated.
 
Hi. I've done a bit more research on units. There are two systems i.e. Conventional (ng/mL) and SI (nmol/L). My units appear to have been in Conventional units but are shown as ug/L which I think if my conversions are correct is equaivalent to ng/mL as there are 1000 nanos (n) in a micro (u). Google shows the normal range to be around 1.1 to 4.4 ug/L. You therefore need to know your units of measure. Note that to convert Convential to SI you multiply by 0.33 i.e. 1 ug/L is the same as 0.33 nmol/L. If your units are SI then your c-peptide could be high'ish but if the same units as mine then your c-pep is low assuming a missing decimal place?
 
Many thanks again, Daibell. I'm fairly sure my result was on the high end, but the only way to make certain is to talk to my gp and found out the units for the 1029.
I thought this test would make everything clear - I was told that I was likely to be T1 when first diagnosed in June 2013, but then they were not sure. The opinion has been back and forth from T1 to T2 to somewhere inbetween! I was quite happy with my T1 label and getting used to a nice routine, but now I'm left confused and unsure of my label. I suspect that they will decide that I'm T2 with insulin. I just want to know what I am!
Thanks again and best wishes to you.
