Used in clinical and research laboratories to detect and quantify abnormal prothrombin, also known as des-γ-carboxy prothrombin (DCP), which is a biomarker associated with hepatocellular carcinoma (HCC). This ELISA kit enables early detection, monitoring of tumor progression, and assessment of treatment response in liver cancer patients. It is particularly valuable in differentiating HCC from other liver diseases such as cirrhosis or hepatitis when used alongside imaging and other tumor markers like AFP. The assay supports high-throughput analysis with high sensitivity and specificity, making it suitable for both diagnostic research and large-scale epidemiological studies.
