OBJECTIVES: To reduce the cost of HIV testing and make it easier by avoiding the use of Western Blot (WB) test. METHODS: We have tested 7460 samples of patients since January 91 till October 97 by our classical strategy wich uses a screening by Elisa and a particules agglutination test (Pat) and the positives were tested in WB, since 92 till 94, we have tested 10,994 samples in epidemiological studies by using the classical strategy. In the 1996 epidemiological study, 11,796 were screened only by Elisa, the positives were tested by Pat and the positives by this test were analysed by WB as a third test. We evaluated the costeffectiveness of an alternative strategy wich uses a screening by Elisa and the positives are tested by Pat. The negatives by Pat are reported negative, the positives by Pat are reapeted in Elisa and Pat. Only the positives by Pat are reported positive. RESULTS: (Table) TABULAR DATA, SEE ABSTRACT VOLUME CONCLUSION: A strategy for reducing the cost of diagnosis and surveillance studies of HIV infection has been assessed in term of costeffectiveness. Since the HIV prevalence is low in Morocco (5.2% in the tested population), a third test more specific is necessary.
