Objective: To determine sensitivity, specificity, positive and negative predictive value of the ADA TEST for the tuberculous Meningoencephalitis (TB-MEC) diagnosis in both sexes patients infected with the HIV, hospitalized at the Internal Medicine pavilions of the “Arzobispo Loayza National Hospital”. January – December 2006. Material and Methods: A Cross-sectional study was made. 201 clinical histories of patients with HIV/AIDS hospitalized during January - December 2006 were reviewed. Only 48 histories fulfilled the selection criteria. Results: 29 cases were men (60.4%) and 19 women (39.5%). The greater proportion of cases was found in the range from 26 to 35 years (39.5%). There was found tuberculous meningitis in 16 cases (33.3%), cryptoccocal meningitis in 20 cases (41.6%), cerebral toxoplasmosis in 6 cases (12.5%), viral meningoencephalitis in 4 cases (10.4%), and one neoplasic case. The prevalence of tuberculous meningoencephalitis was 33.3%. The sensitivity was 93,8 (71,7- 98,9), the specificity was 71,9 (84,5- 59,6) and the predictive values positive and negative were 62,5 (42.7-78.8) and 95,8 (79,8- 99,3) respectively, with a 95% of confidence value. The ROC Curve gave a 6.1 U/L as cut point with a sensitivity of 93,8% and a specificity of 71.9%, with an area under the curve of 89%. Conclusion: The ADA test is a reliable test for the diagnosis of tuberculous meningoencephalitis in HIV patients. Key words: sensitivity, specificity, predictive values, ADA test, HIV infection, tuberculosis
