How is the “intact” PTH assay value interpreted?
According to publications, if an “intact” PTH assay value is less than 100 pgm/mL, there is an 83% probability that the renal patient has adynamic low bone turnover disease. For patients with an “intact” PTH assay value of greater than 100 pgm/mL, the CAP /CIP ratio can be helpful. (ref. Monier-Faugere, Malluche, et. al., Kidney International, 2001; 60:1460-1468.)
