SHANGHAI Blood Center is the first one in the country to conduct advanced tests on all blood samples to ensure blood safety.

Using the nucleic acid testing technology, the window period of hepatitis B can be shortened from 50 days to 25 days, hepatitis C from 72 days to 59 days and HIV from 22 days to 11 days.

Over 90 percent of hepatitis B infection and over 75 percent of HIV infection occur during the window period -- the time from infection until a test can detect the infection.

Shanghai began to experiment with nucleic acid testing two years ago as part of a national program and has applied the technology to all blood samples.

Shanghai Blood Center officials said the new technology has succeeded in detecting hepatitis B virus, which was missed by traditional screening methods.

The national health authorities have decided to introduce nucleic acid testing to more regions this year.


上海市血液中心是在该国的第一个先进的所有血液样本进行测试，以确保血液安全。

乙肝窗口期使用的核酸检测技术，可以从50天缩短至25天，C型肝炎从72天至59天，艾滋病毒从22天至11天。

乙型肝炎病毒感染的超过90％，超过75％的艾滋病毒感染发生在窗口期 - 从感染的时间，直到一个测试能够检测感染

上海两年前开始尝试使用核酸检测作为一项国家计划的一部分，并已申请技术，所有的血液样本。

上海血液中心的官员说，这项新技术已成功地在检测乙肝病毒，这是由传统的筛选方法错过。

国家卫生当局已决定今年引进核酸检测到更多的地区。
