High parathormone (iPTH) values in the patients having parathyroid autotransplantations can be derived from parathyromatosis or preanalytical differences. In this report, we presented a patient with kidney failure and factitiously high iPTH levels. Because of tertiary hyperparathyroidism, total parathyroidectomy and 1/2 parathyroid tissue autotransplantation to brachioradial muscle in right forearm operation has been performed. Although he has been followed with high iPTH levels for a long time, he does not have parathyromatosis. iPTH level was found normal when blood samples were taken from the other arm. High iPTH levels are thought to be related to the place where the blood samples taken i.e., samples taken from the proximal region of autotransplantation, we recommend the blood sample should be taken from the contralateral or distal region of the autotransplantation in order to avoid misdiagnosis and unnecessary and incorrect procedures in patients with parathyroid autotransplantation.
