Bone Formation Speed Test - Procollagen Type I N-Terminal Propeptide (PINP) Test

Measures concentration of Type I Procollagen Amino-Terminal Propeptide (PINP) in serum. PINP is a byproduct during type I collagen synthesis, which constitutes more than 90% of the organic bone matrix, making it a sensitive and specific serum marker of osteoblast activity (bone formation).
