CDC guidelines: For CDC guidelines regarding testing for HIV see the site below. Nucleic acid testing for HIV is more sensitive and specific. http://www.aidsmeds.com/articles/CDC_testing_protocol_1667_25832.shtml

HIV: It is conceivable that one might test negative by PCR at a very early stage of acute HIV infection, although that is not a likely occurrence. The follow-up with a DUO test which measures p24 antigen and antibody to HIV in 28 days seems unnecessary, and repeating the PCR might be more appropriate, although far more expensive.
