PNAS:HIV新突破,血液检测成为过去,唾液检测准确率100%!

在一份最新的报告中,研究人员表示,一项基于唾液的实验性艾滋病检测显示出了希望。这项新的测试能够像血液测试一样可靠地检测出唾液中HIV抗体的早期证据。

研究人员表示:“艾滋病的检测越早确定越好,这样可以减少感染其他人的风险,尤其是年轻人,目前最常见的检查HIV感染的方法是在血样中寻找抗体。但这需要使用针头,而且很难快速测试很多人以控制艾滋病毒的传播。”

据统计,很多艾滋病的高危人群并没有定期的进行艾滋病血液测试,但如果唾液就能检测艾滋病病毒,那么接受检测的人群一定会扩大很多。

HIV抗体在唾液中的累积速度或水平与血液中的速度或水平不同。研究人员在一份新闻稿中说,当现有的唾液测试检测到它们时,说明HIV已经存在了很长时间了,感染者可能已经将艾滋病病毒传染给了其他人。

但是,新的唾液测试显示,在HIV感染早期检测少量抗体是有希望的。在使用其他方法检测出艾滋病毒呈阳性的22人中,它正确地诊断出了艾滋病毒。它也没有在22名HIV阴性参与者中错误地检测到HIV病毒。研究人员说,还需要进一步的研究来证实结果。

这一研究结果发表在《美国国家科学院学报》上。
