Explanation:

HIV tests are performed by collecting a drop of blood from the fingertip. The blood is placed in two testing devices and to reach the result, the tester follows a scientifically determined flow. If both devices have the same results, the diagnosis is already closed, ie if both devices indicate that the patient is infected with HIV, the diagnosis is completed and the patient is already referred for treatment without the need for further tests. However, if there is disagreement between the results, another test is performed with a third for confirmation. Thus, the result has the same reliability as conventional exams and there is no need for repetition in the laboratory.

This method allows the patient to take the test in half an hour, know the result and receive the necessary counseling service.
