title: False-negative syphilis treponemal enzyme immunoassay results in an HIV-infected case-patient.
abstract: We present a case report of a false-negative syphilis treponemal enzyme immunoassay test result in an HIV-infected male. While treponemal tests are widely considered to be more sensitive and specific than non-treponemal tests, our findings point to potential challenges using the reverse sequence syphilis screening algorithm.
