| Resumo: | The test results have to be accurate, and the interpretations of these findings must be correct, given the medical and social significance of a positive anti-HIV antibody testing. This study aimed at evaluating the performance of 19 laboratories participating in the IAL – External Quality Assessment Program for HIV serological assays (EQA HIV). The external evaluation was carried out to help the participant laboratories in monitoring the accuracy of their results, thereby offering better quality to the services provided to the population. Four rounds of the Program were performed in 2014. And for this purpose, the serum panels (test items) were characterized for the anti- HIV antibody reactivity status by using different immunodiagnostic testing approaches. The panels of these characterized samples were distributed to the participating laboratories. The analysis on the test items was performed by anti-HIV serological assays used in the respective participant laboratory routine. Of 17 laboratories participating in the screening assays assessment program, 16 presented 100% satisfatory performance and one got 96.7%, as it presented an inadequate test item result. In the confirmatory trials, the annual satisfatory assessment of the participants was 100%, except for two that obtained 75% due to non-compliance with the rules established by the Program. The IAL – EQA Program for HIV evidenced the implementation of the activities developed in the laboratories, based on the competence of human resources, and certified the use of high quality diagnostic reagents, which are crucial to produce reliable laboratory results. |
