A 27-year-old man has fever, macular rash, and lymphadenopathy. He had unprotected sex with amale partner 2 weeks before the onset of these symptoms and has just learned that the partner isinfected with human immunodeficiency virus (HIV). The patient’s rapid HIV test is negative. What isthe best test to evaluate this patient for HIV infection? A: HIV enzyme-linked immunosorbent assay (ELISA) B: PCR for HIV RNA C: Western blot testing D: Glycoprotein 120 ELISA testing E: PCR for HIV DNA
