Hi, I'm type 1 since august 2011, 24 years old, 178cm, 77 kg, eat around 200-250g carbs daily. I'm on 3x8 Actrapid and 8 units Insulatard (even with 6 or 7 units Insulatard I'm in 5's or 6's in the morning), last Hba1c is 5,3 %. My endo said that I should do C-peptide (I never do this before) because my Insulatard was very little according to her. I have no family history and never been overweight.

Today came my result: 0.439 nmol/L Reference values: 0.37 - 1.47
So what this mean?

Quite simply 'normal' ranges are the reference values: 0.37 to 1.47
Therefore as your result came back: 0.439 it was within normal range.

A C-peptide test measures the level of this peptide in the body. The reference range is just a guide. The ranges vary from laboratory to laboratory and yours may have a different range for what other labs class as normal. Your result shows the range your lab has used. Your doctor will evaluate your results based on your health and other factors. This means that a value that falls outside the normal values may still be normal for you or your lab. The level of C-peptide in the blood must be read with the results of a blood glucose test. Both these tests would be done at the same time.

I would advise you to always discuss your results with your Dr to clear up any confusion, maybe another appointment or phone call is in order? There is no way anybody here can give you a definitive answer as to what those results mean for YOU.
 
Obviously as the previous poster says you need to discuss things with your doctor.
When your body produces insulin it produces C peptide at the same time, injected insulin doesn't have any C peptide associated with it. Your C peptide result (should normally be a fasting test) shows that you are producing some insulin of your own. Your results are at the low end of normal. As you are fairly recently diagnosed, it is quite possible that you are in a honeymoon period which results in you only needing a small amount of injected insulin to supplement what your body produces. .
see honeymoon:

lots of detail on C peptide

But I'm on these units insulin since august. So to be in honeymoon doesn't mean to decrease the amount of insulin? Mine are still the same almost five months, so am I in "honeymoon"?
Thank you

No, but people in the period after diagnosis often use less insulin than they may do later on. Follow your doctors advice on the amount of insulin you should take.
