Search Links: General Info : Protocols : LabTestsOnline

DescriptionAlso known as procollagen extension peptide. Procollagen 1 (P1NP) concentrations reflect osteoblast activity so any disease increasing the activity of osteoblasts or activation frequency of the bone forming unit will result in elevated P1NP concentrations. Low P1NP may indicate adynamic bone. This test is currently only available for Dr SM Orme for monitoring Teriperatide therapy.
Indication P1NP is useful in monitoring response to anti-resorption therapy.
Additional InfoP1NP shows minimal circadian rhythm or seasonal variation and food intake or diet show no detectable influence on serum levels.
