Used in biomedical research to measure levels of human Type III procollagen peptide (PIII NP) in serum or plasma samples. This assay helps assess collagen synthesis, particularly in conditions involving tissue remodeling such as liver fibrosis, cirrhosis, and other fibrotic diseases. Commonly applied in clinical studies and drug development to monitor disease progression and response to antifibrotic therapies. The kit enables quantitative analysis, supporting research in hepatology, dermatology, and connective tissue disorders.
