I had my C-peptide level checked back in March 2011 before considering an insulin pump. My level came back at less than .10ng/ml (normal range per my lab was .80-3.10). My fasting BG at the same time was 72. Recently, my Medicare provider said I needed a new c-peptide and fasting BG done at the same time to qualify for my insulin pump supplies in 2015. I suggested that I should be able to send them a copy of my 2011 test since it is highly unlikely that I would have recovered the ability to produce insulin (which is what the C-peptide measures) and retesting would be a waste of time and money. They finally agreed that the 2011 lab work was acceptable. This prompted me to google C-peptide to refresh my memory about what it is. This WebMD link provides a good explanation of why a C-peptide test is ordered and what it measures. I thought it might be helpful. http://www.webmd.com/diabetes/c-peptide

My c peptide was 3.3 and I'm still considered a type 1 by my dr. I have a appointment on March 3 and that is one of my questions I am going to ask because I am really confused about the whole deal

Medicare is funny this way. They did this kind of weird requirement for my husband for years. He's in a wheel chair, he doesn't walk, he can't even straighten his knees to stand up....every year they would have us get a doctor to tell them that he is a paraplegic. It is nuts. They really don't understand what they are asking sometimes. I know my answer is a little off topic, but fits.

Did you tell them if your levels had improved you would be telling the cure to everyone now?

Navigated through Medicare, I have learned, is not for the weak of heart. I would be trumpeting my good fortune were I indeed able to produce insulin again after 38 years as a Type 1!

Yes Lou this is very helpful. Sometimes in the past I intended to speak about this test as a benchmark to determine if one's pancreas is producing insulin, but I got it mixed up with some other test.

God's best to you
