The purpose of this study is to determine the efficacy of two rapid diagnostic tests in plasma, venipuncture whole blood, and fingerstick whole blood. The clinical performance of Multiplo HBc/HIV/HCV will be determined by comparing the results with patient infected status for HIV-1/2 (human immunodeficiency viruses 1 and 2), HBV (hepatitis B virus) and HCV (hepatitis C virus). The clinical performance of Reveal HBsAg will be determined by comparing the results with patient infected status for HBV.
