Abstract
Human immunodeficiency virus (HIV) nucleic acid testing is increasingly being used by researchers and public health screening programs to identify highly infectious, HIV antibody-negative individuals with acute HIV infection. We present cases to illustrate unusual instances of acute HIV screening, which include "window period" testing and the discovery of low-level HIV RNA.
