No. O exam what detects if you have the AIDS virus is a specific blood test called anti-HIV.
The diagnosis of HIV is made from the specific blood test.
There are several types of tests available: screening test, confirmatory test, molecular tests. In these tests, the patient performs blood collection in the laboratory and the result is released on average after 4 hours.
The quick tests have gained visibility for ease of achievement, accessibility and speed of release, which can take less than half an hour. They can be made from a drop of blood taken from the person's finger or from the saliva picked up by a device. Rapid tests are available in mobile units and in some health facilities and hospitals.
Although it is currently rare, failure to diagnose can occur, and in some cases it may be necessary to repeat with other tests for confirmation. Another consideration you should have is the issue of immunological window, the period in which the virus is present in the person's body, but there has not yet been an immune system response that can be detected in the tests.
All these tests are free and can be done at any time in the Mobile Test Units or Health Units of the Unified Health System (SUS).
