Used in clinical and research laboratories to quantitatively measure 17-hydroxyprogesterone levels in human serum or plasma. This kit supports the diagnosis and monitoring of congenital adrenal hyperplasia (CAH), particularly the 21-hydroxylase deficiency form, which is a common endocrine disorder in newborns. It is also utilized in fertility studies and adrenal function assessments, providing a reliable tool for hormone evaluation in reproductive and pediatric endocrinology research. The ELISA format allows for high-throughput screening with sensitive and specific detection, making it suitable for both diagnostic development and investigative studies.
