factitial hypoglycemia from the surreptitious self-administration of insulin by an insulin-dependent diabetic , shown to have c-peptide secretory ability by glucose and tolbutamide stimulation tests , was strongly suspected by finding low plasma c-peptide immuno-reactivity and high plasma insulin levels during `` '' spontaneous '' '' hypoglycemia whereas during hyperglycemia the d-peptide immunoreacitivity was higher and the plasma insulin was lower .
