A rapid confirmatory test for HIV, called Immunoblot was announced during the second. Immunobiological International Symposium organized by Bio-Manguinhos Institute, which is happening this week in Rio de Janeiro. Agreement signed between the institute and the American laboratory Chembio enabled the fabrication of two rapid tests developed in Brazil. The screening test was announced in February.

In the current procedure, people do the screening test using ELISA and return to the search result. If it is positive, they are directed to an additional test, which can be done by the method of immunofluorescence or western blot, the latter being the most common. The final result comes out in a few days.

The biggest problem faced by the SUS in this case, according to the Ministry of Health, is that 40% of those who make HIV testing do not return to get the test results. The idea with these new tests is that people are already leaving the service unit with the final set and routing.

Initially, tests will be available for higher risk groups like sex workers, pregnant women who had not had any prenatal care and the homeless. To take the test, a sample if blood is collected with a finger prick and the result can be known in just 20 minutes. "The kit is sensitive and effective as from the 25. Day of infection," said program manager for the Development of Reactive, Antonio Ferreira.

The government expects to completely replace the current system by the new rapid tests in a maximum of two years. Initially, the Bio-Manguinhos has the capacity to produce 200 thousand sets per year at a cost five times less than the current kits.
