The Procollagen Type I Intact N Terminal Propeptide (P1NP) Test evaluates bone metabolism by quantifying markers of collagen formation. P1NP levels rise with accelerated bone turnover seen in osteoporosis, Paget’s disease, or healing fractures, and decline when bone formation is reduced. By providing insight into skeletal remodeling, this test helps assess metabolic bone disease, monitor therapeutic response, and guide management of bone health.
