conclusions io-pth levels should become normal or to drop by at least 80% during successful parathyroidectomy. persistent elevations of io-pth after resection of an abnormal gland dictate the need for bilateral exploration. background we hypothesized that io-pth levels would decline to normal or near normal after successful parathyroidectomy. objectives evaluate efficacy and predictive factor o...

pth is the most important factor which control calcium homeostasis in the body in this study we tried to determine the normal range of pth and vitamin d with examining the relation between pth and bone density and vitamin d on the base of bones biological changes. our subjects were, 20 to 69 years-old men and women of tehran. serum volume of pth and vitamin d in different decades of life had si...

For measurement of parathyroid hormone (PTH), the intact PTH (I-PTH) assay is generally used. However, I-PTH assay apparently detects PTH 7-84 fragments, in addition to PTH 1-84. The whole PTH (W-PTH) assay exhibits no cross-reactivity with PTH 7-84. Ratio of PTH 1-84 to non-(1-84) PTH has been proposed as a non-invasive indicator of bone turnover in patients with end-stage renal disease (ESRD)...

BACKGROUND Determination of plasma parathyroid hormone (PTH) is routinely performed to diagnose and monitor renal bone disease. Recently, a new PTH assay ('whole PTH') using an antibody directed specifically against PTH(1-4) has been introduced. It was the aim of the current study to evaluate whole PTH and parameters derived from whole PTH in renal bone disease. METHODS The following measurem...
