[Parathyroid hormone values in patients on chronic dialysis treatment]

It has been stressed that the values of radioimmunologically determined PTH in patients on chronic dialysis treatment are considerably high and the duration of dialysis treatment has no marked effect on them. Relatively good correlation dependence between the serum levels of calcium and PTH is established only in the presence of hypocalcemia. In all other cases the correlation dependence between PTH and calcium as well as that with phosphorus and alkaline phosphatase is negligible so that their serum values cannot be used to judge the level of PTH. The dynamic follow up of the PTH values is emphasized to be performed with one and the same kit, hence avoiding the methodical errors.
