Osteomark® NTx Urine test kit is produced by Tianjin Hopeyear Medical Products Co., Ltd. The kit can quantitatively detect I-type collagen cross-linked amino terminal peptide (NTx) in human urine. NTx is a marker of bone resorption. The increased level of urine NTx indicates the increased level of bone resorption. The kit can be used to predict the bone response (bone mineral density) of postmenopausal women treated with hormone anti-absorption therapy. Treatment monitoring: anti-absorption treatment of postmenopausal women, anti-absorption treatment of patients diagnosed with osteoporosis, anti-absorption treatment of patients diagnosed with Paget's disease, and hormone suppression treatment. Verification of the association between calcium supplementation and bone density reduction one year after hormone anti-absorption treatment in postmenopausal women.
The Osteomark NTx Urine assay is an in‑vitro diagnostic test that quantitatively measures cross‑linked N‑telopeptides of type I collagen (NTx) in human urine. It is intended for predicting and monitoring bone‑resorptive therapy in post‑menopausal women, osteoporosis, Paget's disease and related conditions.
The kit uses a competitive‑inhibition ELISA format with NTx‑coated microwells and a monoclonal antibody‑HRP conjugate. The manual details reagent preparation, specimen collection, assay procedure, calibration, and result interpretation, along with safety warnings and storage requirements.
