Use of simian immunodeficiency viruses for AIDS research.

abstract：OBJECTIVES:In the present study, we aimed to determine whether signal-to-cutoff (S/Co) ratios of reactive anti-HCV samples could be used as a basis for avoiding the need for supplemental testing in our study population. METHODS:We analyzed 901 anti-HCV-positive sera from 8 institutions in China. The Ortho VITROS anti-...
