Current issues with current procollagen III N-terminal peptide (P3NP) assay performance relevant to 2016 British Association for Dermatologist methotrexate-monitoring guidance
David R Taylor, Colin Stone- Dermatology
Procollagen III N-terminal peptide (P3NP) testing is routinely used to detect possible liver fibrosis according to cut-offs in the British Association of Dermatologists (BAD) 2016 guidelines for the safe and effective prescribing of methotrexate in skin disease. We report significant and changes to P3NP test performance that will potentially change patient management according to the BAD 2016 guidelines.
