Interpretive Data
This test provides a quantitative determination of Cyclase Activating PTH (CAP) or whole parathyroid hormone (PTH 1-84) and total immunoreactive intact PTH (Total Intact PTH) to aid in the diagnosis of parathyroid disease. 1-84 PTH binds to the PTH/PTHrp receptor and operates through the adenylate cyclase stimulating pathway.
