In recent years rapid tests have been gaining importance in the diagnosis of HIV infection and other sexually transmitted infections. Although sensitivity of the newer tests is comparable to Immuno-enzymatic assay, the specificity is lower.  The purpose of this study is to examine the performance of the rapid tests used in Bata Regional Hospital, Equatorial Guinea for HIV, B and C Hepatitis, and Syphilis assessing if they are really useful and the best for detecting diseases or health conditions of the individuals.  An observational, analytic, and cross sectional study was performed including the diagnostic tests and sensitivity, specificity, positive and negative predictive values, so as the positive and negative probability ratios, with 95 % confidence intervals and calculated for every test respectively.  Agreement was proved using Cohen Kappa test at 95 % of confidence level.  From de 356 specimens, 193 (54.2 %) showed positive results for the entire set of tests. The probability of that, a rapid test correctly diagnose a person suffering from a disease was 70.6 %, showing variations among the different tests.   The rapid test diagnoses better the sick person, but the healthy ones not always can be ruled out.  The confirmation of the diagnosis must be carried out using other techniques, rarely available in this country.
