"Identifying acute infections has long been one of our nation's biggest HIV prevention challenges, since these infections eluded traditional testing technologies. But with consistent and widespread use of this new testing method, we can diagnose people several weeks earlier than before. CDC is support...
Evidence demonstrating the benefits of early and accurate diagnosis of HIV infection has been increasingly documented and this was reflected on the algorithm proposed by Centers for Disease Control (CDC, Atlanta, GA) in 2010 which begins with 4th generation screening tests that detect HIV p24 ...
It also recommends that HIV testing be part of the routine consent form rather than a separate form. The CDC states that you should never be tested for HIV without your knowledge. What does it mean when an HIV test says non-reactive? A non-reactive test means the screening found no sign...
图3. 美国CDC在2014年更新的HIV实验室报告导则 5.弱化抗体免疫印迹确认试验的地位:是出于对抗体检测局限性的考虑 病原体抗体检测的局限在于:①免疫系统功能损害的感染者,不能产生足量病原体特异性抗体,导致血清学阴性的HIV、HCV等感染;②抗体检测有更长的“窗口期”[11],检测极早期感染的灵敏度欠缺。如果献血员...

HIV感染:检测、咨..HIV感染通常首先表现为短暂的急性逆转录病毒综合征,而后过渡到持续多年的慢性疾病,在这个慢性过程中维持适应性免疫功能的CD4T淋巴细胞逐渐耗竭,最后出现症状,生命终结于危及生命的免疫缺陷。感染的最后阶
95%CI，34-55），意思是平均为42天，有95%的概率是在34天到55天之间，所以最早CDC和三甲医院把HIV...
大家要明白一点,医学专家和CDC在讨论行为风险的时候有必要保持过度的保守。所以,**是有一个极小的所谓的“理论”风险。如果**真有“事实”的风险的话,那么应该总能发现一些通过这种行为感染的新病例。但是绝对没有。同时“理论”的风险和实际的风险有很大的不同。两位专家(Dr.HHH和Dr.Hook)经常说,在他们两个...
