HIV I & II Antibodies(Tridot)
To determine if a person is infected with human immunodeficiency virus (HIV).
When there is a suspected exposure to the virus, before or during pregnancy, once a year if a person is at increased risk of exposure to the virus.
HIV antibody and HIV antigen (p24) testing are the tests used to screen for and diagnose HIV infections. Early detection of HIV infection enables treatment initiation and immune system monitoring which can improve long-term health and survival of the infected patients. It is also important to bring behavior changes by knowing the HIV status.HIV antibody and antigen testing are both important for screening and diagnosis. Screening HIV screening test includes a combination of HIV antibody and HIV antigen test. It can be done only using a blood sample. It detects both the HIV antigen called p24 and antibodies to HIV-1 and HIV-2. Soon after the initial infection by HIV virus, the level of p24 antigen and the viral load increase significantly. Testing for p24 antigen allows early detection of HIV infection before HIV antibody is produced. the antibodies to HIV are produced, a few weeks after the HIV infection and the levels remain detectable in the blood thereafter. Detection of both antibody and antigen indicates that the infection is detected soon after exposure, within 2-6 weeks. p24 antigen testing is used alone without the antibody test only in rare cases when interference with an HIV antibody test is suspected. Diagnosis If any of the screening tests are positive, then it must be confirmed by a second test to establish a diagnosis. If the second test does not agree with the first test, then a third test is performed that detects the RNA of the virus. An HIV RNA test will detect HIV infection within 1-4 weeks of infection.
1. What are the symptoms of HIV?
Initial symptoms can mimic those of influenza and other viral infections. Few people with HIV infection may remain asymptomatic for several years after the initial or may have symptoms that are very similar to other illnesses.
2. What is the treatment for HIV/AIDS?
Currently, there is no cure for HIV infection or AIDS. However, there are treatments that can improve immune function and reduce the risk of opportunistic infections, and prolong life. People typically take at least three drugs from two different classes. Combinations of three or more antiretroviral drugs are referred to as highly active antiretroviral therapy or HAART.
3. Can HIV antibody test detect HIV in newborns?
No. maternal antibodies are transferred to the baby and remain for 6-12 months, hence a different test that detects the genetic material, either an HIV RNA or HIV DNA test, is required.
