Used in biomedical research to measure levels of parathyroid hormone (PTH) in biological samples such as serum or plasma. This ELISA kit enables researchers to quantify the active fragment of PTH, which plays a key role in calcium and bone metabolism. It is widely applied in studies related to bone diseases, osteoporosis, hyperparathyroidism, and kidney-related mineral disorders. The assay supports high-throughput analysis with high sensitivity and specificity, making it suitable for both preclinical and clinical research settings. It is not intended for diagnostic use but serves as a critical tool in endocrine and metabolic research.
