The results confirm you're negative for antibodies. The less than sign doesn't support a value. It just means the antibodies aren't detectable below this value which is classed as negative.
Yeah I think those just say you're less than those values, doesn't say what exactly your values were, so you cant say whether you were close or not to those values
Your c-peptide is really high and would support insulin resistance and type 2. The fasting range is: : 0.26-0.62 nmol/L and 1.31 is above the normal range.
Converting to pmol/L so you can read the attached chart used by the Exeter University diabetes team who run the nationwide c-peptide trials: yours is 1310 pmol/L. The cut off for type 2 fasting is greater than 250 pmol/L and you are way above that.
