WebCirculating large C-terminal PTH fragment levels are increased in uremic patients. However, this noninvasive study failed to demonstrate the superiority of the specific 1-84 assay compared with the conventional iPTH assay to evaluate bone metabolism. WebMay 3, 2024 · Due to the short half-life of PTH, this 84 amino-acid polypeptide hormone is produced at low circulating levels in normal conditions ranging from 10 - 65 pg/mL. In addition, N-terminal and C-terminal peptides, which have shown to interfere with clinical analyzer platforms, account for over 80% of all circulating PTH levels.
