The Testing and Counseling Centers are important sources of epidemiological information. This study describes a research conducted with the users of the Testing and Counseling Center of Rio Grande-RS submitted to anti-HIV test during the period 2001-2004. Demographic and behavioral factors of individuals attended in the service were analyzed using the database SISCTA-2002/RG. HIV-1 seropositivity between 2001 and 2004 was of 1,1%; 2,4%; 2,3% and 1,7%, respectively. In 2003 and 2004, 37,7% and 36% of the HIV-1 positive patients did not return to the Testing and Counseling Center for getting the result of their serological anti-HIV or confirmatory tests. These results seem to reflect some tendencies of the HIV epidemic in Rio Grande and in Brazil. It is important to emphasize the high percentage of HIV-1 positive patients who do not return for getting the result of their test. In terms of public health this risk behavior may jeopardize the efforts for controlling the epidemic.
