--with her bone and other problems, and with the presence of anti-thyroid peroxidase antibodies, they're looking for autoimmune thyroid conditions in Roxie's case by doing the thryoid scan:

There is likely a suspicion of systemic metabolic disorder with her gastrointestinal transit situation, so they're also looking into the whole diabetic angle (that's what the C-peptide test is all about--it's a by-product of insulin production, and the higher level implies high insulin production, which would be conssitent with both insulin resistance and that hypoglycemic reading).

My suspicion, though, is that an insulin imbalance might be secondary to the gastrointestinal problems; and given that evidence of autoimmunity, I wonder if this might be a good time to test for celiac again . . .

Hi Roxie:

Glad to see you are still with us... I actually thought they must have left off the first number...

If you are having a thyroid scan, it must be different than the one I had. Although I did have to swallow a capsule the day before and then return the next day for the nuclear scan, I don't recall it lasting an hour and a half...

for my scan I had to have and IV radio isotope! I have hard to hit veins...
so it was not pleasant!
