| Sensitivity on test differs. Not an expert on the c-peptide test but just from looking it appears that different tests have varying ranges. My reference of .9 had to do with the classification scheme for ketosis prone T2's. It states that B positive starts at .9 c-peptide. The how and why they picked that particular cutoff escapes me but it did involve a bit more than tossing darts at a board.
