title: [Comparative study of parathyroid function by serum parathyroid hormone, total adenosine cyclic monophosphate in the urine and its nephrogenic fraction].
abstract: The immune heterogeneity of the parathyroid hormone and the possibility of its peripheral activation by 1.25 (OH)2 vitamin D3 hinders the precise evaluation of the functional state of parathyroid glands by direct determination of the hormone in the serum and also the creation of a suppressive test similar to the suppressive tests applied in the study of other hormones. A study was carried out which proves that the indirect examination of the parathyroid function by determining the cyclic adenosine monophosphate in urine and its nephrogenic fraction (i.e. by the effects of the active parathyroid hormone) is of greater importance for clinical practice than the direct determination of the parathyroid hormone in peripheral blood. This is the method of choice in the diagnosis of the subclinical variant of primary normocalcemic hyperparathyroidism.
