Make positive contributions to the benefit of mankind

According to the world health organization, 40 to 50 percent of women in developed countries are screened for cervical cancer each year, but only 5 percent of women in developing countries are. In may, the world health organization ordered a global campaign to eliminate cervical cancer.


In theory, wafer-based cytological examination combined with a second-generation hybrid capture technique is the best combination for cervical cancer screening, qiao said. But the only problem is that the cost of such a test is more than 500 yuan, which the women in the poor areas simply cannot afford.


At present, acetic acid staining observation is the main method of cervical cancer screening in poor areas. "The test only costs about 10 yuan, but the results are not satisfactory. If the gynecologist is not well trained, the rate of missed diagnosis can be as high as 40 percent. "Said qiao youlin.


Therefore, it is necessary to find an economical, accurate and effective cervical cancer screening method. After five years of tedious screening and numerous failed tests, clinical trials of the technology were finally announced in late 2007. The study was published in 2008 in the world's leading medical journal, lancet oncology, and published for review.


The data showed that the careHPV rapid screening technology had a sensitivity of 89.7% and a specificity of 84.2%, close to the second-generation hybrid capture technology commonly used in developed countries and regions. In addition, screening time has been significantly shortened. Second-generation hybridization capture results in seven hours, whereas rapid screening takes just two and a half hours.
