CICP (PICP) (C-Propeptide of Type I Procollagen)
|5 days||26 days||2 years|
Type 1 Collagen is a primary organic constituent of bone. The release of these peptides into the circulation as the result of the cleavage of type I collagen (CICP) provides a stoichiometric representation of the production of collagen.
Type I collagen levels have been linked to bone growth and formation. Levels of CICP are indicative of collagen production in vivo. Elevated levels of CICP have been shown in diseases associated with high levels of bone turnover, including Paget’s disease (see reference 1), hyperthyroidism, primary hyperparathyroidism and renal osteodystrophy. Slightly elevated levels of CICP have also been documented in some women in early menopause (see reference 2).
The CICP assay is a solid-phase ELISA designed to measure human CICP in serum and plasma. It employs the quantitative sandwich enzyme immunoassay principle.
