Used in biomedical research to measure levels of procollagen type III amino-terminal peptide in serum or plasma samples. Helps assess collagen synthesis and tissue remodeling processes. Commonly applied in studies of liver fibrosis, where elevated levels indicate active fibrogenesis. Also utilized in dermatology research to evaluate skin repair and wound healing, as well as in monitoring fibrotic diseases in organs such as the lungs and kidneys. Provides a quantitative tool for investigating the progression of fibrosis and the effectiveness of antifibrotic therapies in experimental models.
