Abstract

The invention relates to a serum CENPF antibody quantitative detection kit which can be used for specifically and quantitatively detecting the level of a CENPF antibody in a serum specimen. According to the serum CENPF antibody quantitative detection kit, recombinant CENPF antigen protein is coated in a 96-pore enzyme label board, the level of the CENPF antibody in the serum specimen can be quantitatively tested by using an enzyme linked immunosorbent assay, and the disease state of a liver cell cancer patient or high risk groups can be evaluated according to the level of the CENPF antibody in the serum. By adopting the serum CENPF antibody quantitative detection kit, a novel liver cell cancer screening and early diagnosis method is provided, and the sensitivity of the detected serum CENPF self-antibody is remarkably superior to that of a conventional clinical serum marker AFP when being used for diagnosing liver cell cancer.

Description

technical field [0001] The invention relates to a serum CENPF antibody quantitative detection kit. Background technique [0002] Hepatocellular Carcinoma (HCC) is the main type of primary liver cancer. Due to the lack of early symptoms of HCC, most patients are already in the middle and late stages when symptoms appear, losing the chance of effective treatment, and the survival period is generally less than 1 year. Early HCC can be resected or liver transplanted, and the 5-year survival rate is above 60-70%. . Therefore, timely detection and diagnosis of early cases through regular screening of high-risk groups is crucial. However, at present, there is still a lack of HCC screening and early diagnosis methods with high sensitivity, good specificity, and clinical operability. [0003] An ideal early diagnosis method for HCC should not only have high specificity to distinguish HCC from liver cirrhosis and hepatitis, but also have high sensitivity to detect HCC at an early s...
