Many factors limit the use of screening for acute HIV in high-risk populations, in blood donors and during voluntary HIV testing, including, cost, technique, sensitivity and specificity. In this review we explore a new NAAT method which involves HIV RNA RT-PCR on pooled samples. This technique is able to screen for acute infections in a large testing volume and may be used as a screening method in high-risk populations and blood donors.展开更多
