What makes the SCL 2nd generation Total Intact PTH test unique?
In order to calculate the CIP value by subtracting the CAP value from the Total Intact PTH value, a unique, 2nd generation Total Intact PTH test must be used. This Total Intact PTH test must measure CAP (1-84 PTH) and CIP (7-84 PTH) on an equimolar basis. This means that the same amount of CAP (1-84 PTH) and CIP (7-84 PTH) will generate the same assay value in the unique, Scantibodies 2nd generation Total Intact PTH assay. This is not true of most 2nd generation “intact” PTH tests.
