What are the laboratory tests used to determine HIV?
I - The HIV virus attacks and destroys CD4 lymphocytes in the immune system.
II - The HIV virus is transmitted through the exchange of bodily fluids of the infected person, such as blood, breast milk, semen, or vaginal secretions.
III - The indirect methods for detecting HIV include screening tests, such as ELISA, agglutination tests, Dot-blot, and fluorimetric method.
IV - The direct methods for detecting HIV include the isolation of the virus, the detection of certain fragments of its genes, and the detection of the p24 antigen, which is a viral protein characteristic of HIV.
a) I and II are correct.
b) II and III are correct.
c) III and IV are correct.
d) I, II, III, and IV are correct.

A resposta correta é a alternativa c) III e IV estão corretas. Os métodos indiretos para detectar o HIV incluem testes de triagem, como ELISA, testes de aglutinação, Dot-blot e método fluorimétrico. Já os métodos diretos para detectar o HIV incluem o isolamento do vírus, a detecção de certos fragmentos de seus genes e a detecção do antígeno p24, que é uma proteína viral característica do HIV.
