Immunochemlumenicy pth assay
WitrynaNon-1-84 PTH was determined by subtracting the whole PTH value from that of the intact PTH assay. The median level of whole PTH was 121 pg/mL, and that of iPTH was 210 pg/mL. The whole PTH assay had a very high correlation with the iPTH assay (r = 0.870, P < 0.001). For 43 out of 738 patients (5.8%) the value for intact PTH-whole PTH was … WitrynaConsequently, when measured with an intact PTH assay, concentrations of 1.5 to 3 times the upper limit of the healthy reference range appear to represent the optimal range for end-stage kidney failure patients. Lower concentrations may be associated with adynamic renal bone disease, while higher levels suggest possible secondary or …
