　　艾滋病唾液试纸检测都有“假阳性”的误判可能

　　“用唾液试纸防艾滋病，有用吗？”在近日的艾滋病日的宣传上，很多年轻市民就网上流行的快速检测试纸提问，“发生点啥事前，如果能用这个试纸测测，咱不就有安全保障了吗？”昨天，记者了解到，无论血液检测还是唾液试纸，都有“假阳性”的误判可能，不提倡自己在家里验艾滋。

　　记者在网上搜索“艾滋病唾液检测”字样，结果找到不少销售这种试纸的网站，唾液试纸销售最火热，销售人员都号称准确性很高。但记者了解到，大连艾滋病检测部门都没有引进这种唾液试纸，大家只能在网上购买。它的检测效果怎么样呢？记者采访时，大连疾病预防控制中心专业人士表示，曾经有一个大连小伙，在网上买了唾液试纸在家里连续用了5次，前4次全是正常显示为“阴性”，最后一次，却出现了“阳性”显示，这可把他吓坏了。到底自己有没有艾滋病？是试纸不准确，还是自己的操作有问题？据他跟医生说，自己吓得都想自杀，可想来想去，还是到疾控中心又检测一次。最终结果显示，他非常安全，并没有感染艾滋病。

　　为什么会出现不同结果？微生物科李德钧告诉记者，艾滋检测会出现“假阳性”，即使是正规医院送上来的第一次检测有问题的“疑似”血样，经过确证实验后也有被排除的。所以说，在第一次检测为“阳性”的，也不一定就能确认感染了病毒，还需要做复查和重新抽血做确证。记者采访时发现，无论快速检测准确性如何，是否存在假阳性，医生不推荐市民在家中自行检测的另一个原因是，考虑到大家的承受力。医生做艾滋告知时，都要同时进行患者本人和家人的心理疏导。很多人对艾滋还有不少认识误区，一旦在家里想不开，崩溃了，那不是冤死了。所以说，建议市民应到大连13家疾控中心做免费筛查。

Detection of HIV saliva test strip has a "false positive" miscarriage of justice may be

"Saliva test paper with the anti-AIDS, and useful?" In the recent publicity on AIDS Day, many young people on the Internet, the rapid test strip popular question, "took place Diansha beforehand, if they can use this strip Cece, 咱 do not have safety and security it? "Yesterday, the reporter learned that, regardless of blood test or saliva test strips are a" false positive "miscarriage of justice may not promote their own HIV-testing at home.

Search for news on the Internet, "HIV saliva test," the words, the results find many websites selling the test paper, saliva test strips best-selling, sales staff are known as high degree of accuracy. But the reporter has learned that, Dalian HIV testing department does not introduce such a saliva test strip, we can only be purchased on-line. Test how effective it is what? Reporters, Dalian Center for Disease Control and Prevention professionals say, there was a small group of Dalian, in line to buy a row at home saliva test strips used five times, four times before all is normal is displayed as "negative", the last time, there was a "positive" shows that he may be frightened. In the end they have no AIDS? Is not accurate test paper, or the operation of their own problems? According to him with the doctors said he wanted to commit suicide frightened can be much deliberation, or to the CDC test once again. The end result showed that he is safe and not infected with HIV.

Why is there different results? Micro-organisms Section Li De-jun told reporters that HIV testing would be a "false positive", even if the hospital were brought to the formal tests, the first issue of the "suspect" blood samples, after confirmed after the experiment, there were also excluded. So, at the first test as "positive", and do not necessarily be able to confirm infection with a virus, blood needs to be done to do review and re-confirmed. Reporters found that, regardless of the accuracy of rapid tests, the existence of false-positive, the doctors do not recommend testing for home on their own, another reason is that, taking into account everyone's tolerance. Doctors told to do AIDS, we need at the same time patients themselves and their families psychological counseling. Many people there are a lot of misunderstanding of HIV, once at home and take things too hard, crash, and it was not killed unjustly by. Therefore, the public are advised to Dalian 13 CDC to do for free screening.
