HIV analysis
This analysis is carried out in order to carry out HIV testing. The presence of HIV-HUMAN IMMUNODEFICIENCY VIRUS is defined in the blood, and this virus is the cause of AIDS, namely, acute immunodeficiency syndrome (HIV).
The test is carried out in a method called enzyme-linked immunosorbent assay (ELISA). The analysis is performed using a serum sample or may be taken by a saliva sample, but this test may not produce a good and accurate result, The results may be false, but in order to confirm the accuracy of the analysis, the Western blot test is performed. This test is more accurate than the first test, but it is expensive and technically difficult, which means that many samples are difficult to test.
The body’s immune system takes several weeks to produce antibodies in sufficient quantities so that the results of the test are positive, so the result can be tested for HIV negative (3-6) months, due to the lack of anti-virus in this Duration and even if the person from the sample infected with the virus, and if there are doubts about the presence of the virus and the result was negative, there are other ways to verify the presence of the virus, including the following:
- Testing a virus P24 antigen). This compound of the virus is present in the serum during the first weeks of infection and infection in the patient, and its presence indicates the presence of infection.
- Polymerase chain reaction (PCR). This test shows the genes for the virus in the serum. This is the most sensitive test for detecting the virus if the previous tests are negative.
We should remember that a single positive ELISA test is not enough to diagnose the disease and the presence of the virus that causes AIDS, indicating that other tests are needed to verify and verify the presence of the virus. Western blot. After confirming the positive outcome of the HIV test, the doctor will perform additional tests for the immune system and assessment process.
