HIV核酸定性检测主要采用实时荧光定量PCR方法，HIV核酸定量检测主要基于靶核酸扩增和信号放大两种方法。定性...
health care professionals request or require testing as part of evaluation and treatment for other conditions, such as women undergoing treatment with assisted reproductive technologies for infertilityor treatment ofviral hepatitis. Healthcare personnel and first responders may be exposed...
目前国内厂家的病毒载量检测试剂均是基于实时PCR技术开发的,其他技术例如分支DNA技术已逐步退出载量检测领域。 第二,检测设备趋向于一体化,或者是大型的全自动设备完成样本处理和检测,或者发展成小型的POCT(point-of-care testing,现场快速检验)产品,而核酸等温扩增技术由于对反应条件要求...

Bertozzi说,当这些抗体与我们的蛋白质DNA结合时,抗体的两个分支将两个DNA在空间中紧密地结合在一起。然后可以添加一种酶,它可以将附近的两个DNA分子结合在一起,这样DNA就可以通过PCR检测来扩增。她说,这种新的检测方法比目前的唾液检测方法要灵敏数千倍,目的是检测相同的抗体...
Answer: Any HIV test considered as conclusive only after retesting at or after 12 weeks although PCR test i.e RNA tests can give accurate results much early than other HIV tests. Question: How long does it take to get results of an HIV test?

RNA extracted from plasma of 13 MSM, 9 FSW, and one heterosexual male was amplified by nested RT-PCR and the products were directly sequenced. HIV-1 strains from 21 individuals were characterized with one or more complete genome sequences, and two were sequenced in the Nef gene. The ...
PCR or nucleic acid amplification tests are utilized primarily for testing of newborns with HIV positive mothers and screening of blood supplies, due primarily to expense and complications of the test. View article Point-of-Care Testing Sheldon Campbell MD, PhD, Yuri Fedoriw MD, in Clinics in ...
他们的研究成果发表在了《BMC Health Services Research》期刊上,论文标题是 “Access to diagnostic testing for invasive fungal diseases and other opportunistic infections in Mexican health care centers caring for patients living with HIV”。研究得出结论:墨西哥大多数专门为艾滋病患者服务的公共医疗中心缺乏现场...
