A member asked:
Hypoglycemia symptoms led to a 72-hour fast to rule out insulinoma. glucose low at 49, c-peptide low at .56, insulin serum was low but in normal range. is the c-peptide typically low with fasting ?
A doctor has provided 1 answer
Endocrinologist: Those levels rule out an insulinoma and the C Peptide level may be normal. An endocrinologist is best qualified to interpret your findings and advise you, however.
