   the initial rapid HIV and/or E/CIA, or by HIV-1 antigen, plasma HIV-1 RNA viral load.
   More information on this criterion can be found in the protocol.

   - Laboratory values obtained within 45 days prior to entry by any U.S. laboratory that

   assurance programs:

      1. Absolute neutrophil count (ANC) greater than 750 cells/mm^3

      2. Hemoglobin greater than or equal to 9.0 g/dL

      3. Platelet count greater than or equal to 75,000/mm^3

      4. Serum creatinine less than or equal to three times the upper limit of normal
      (ULN)

      5. Aspartate aminotransferase (AST) (serum glutamic oxaloacetic transaminase [SGOT])
      and alanine aminotransferase (ALT) (serum glutamic pyruvic transaminase [SGPT])
      less than or equal to five times the ULN

      6. Total or conjugated (direct) bilirubin less than or equal to 2.5 times the ULN

   - For men, receptive anal sex (defined as receptive penile-anal sex or receptive

   - Anal cytology result from specimen obtained within 45 days prior to entry

   - HRA performed within 45 days prior to entry by a certified HRA provider with no
   evidence of invasive or microinvasive anal cancer by anal biopsy or by visual
   inspection if no biopsy was obtained. Note: refer to protocol for more information
   about HRA certification process.

   - For women, gynecologic examination (including screening for cervical disease by
   exfoliative cytology with or without colposcopy) within 45 days prior to entry.

   - For women of reproductive potential, a negative serum or urine pregnancy test within
   45 days prior to study entry by any U.S. laboratory that has a CLIA certification or
   its equivalent, or at any network-approved non-U.S. laboratory that operates in

   quality assurance programs. More information on this criterion can be found in the
   protocol.

   - Confirmation of the availability of the anal swab, vaginal swab (women only) and Scope
   oral rinse specimens for HPV DNA PCR obtained at screening. The site must confirm that
   these samples have been entered into the Laboratory Data Management System (LDMS).

      - For all participants: anal or oropharyngeal cancer

      - For men: penile cancer

      - For women: cervical, vulvar, or vaginal cancer

      - More information on this criterion can be found in the protocol.

   - Anal, cervical, or vaginal cytological results suspicious for invasive carcinoma at
   any point prior to entry
