摘要: The aminoterminal propeptide of type I procollagen (PINP) in serum is a sensitive indicator the synthesis collagen. Four assays are available for PINP, two them (intact PINP assays) measure intact and other (total also detect smaller antigen serum. In many clinical situations, these give similar information, but renal insufficiency increases concentration antigen, influencing both apparent assay calibration. Serum mostly affected by changes bone metabolism. infants children, much higher than adults. (s-PINP) useful disease activity Paget's bone, metastases osteoblastic nature, follow-up treatment osteoporosis. IFCC IOF recently recommended use s-PINP as reference marker formation studies concerning fracture risk assessment response.
