The 'Golden Standard' for Serological Detection of Nasopharyngeal Carcinoma
The product was published in the top medical journal The New England Journal of Medicine in 2023, was selected into the 'Important Medical Advances in China in 2023', participated in and won the Second Prize of the National Science and Technology Progress Award in 2023, and was included in the 'Guidelines for the Diagnosis and Treatment of Nasopharyngeal Carcinoma 2024' of the Chinese Society of Clinical Oncology (CSCO).
Core Advantages
Earlier Detection
The detection rate of early nasopharyngeal carcinoma is as high as 94%, enabling early detection, diagnosis, and treatment of the disease.
More Accurate
The specificity for healthy people is over 98%, greatly reducing the false positive rate and alleviating the psychological burden of the examinees.
More Reliable
The positive predictive value of a single indicator is 2.3 times higher than the existing scheme, and the positive predictive value of the P85-Ab combined with the double-antibody scheme is increased by 7 to 10 times. The detection efficiency is significantly improved, reducing the waste of medical resources.
