Diagnosis Of HIV And AIDS


To determine if the patient is HIV-infected, the kudu is executed by HIV test. Screening is carried out by taking over blood samples or urine of the patient for investigation in the laboratory. Screening types to detect HIV are:

Antibody test. This test has the purpose of detecting antibodies produced by the body to fight HIV infection. Although accurate, the kudu pas 3-12 weeks so that the amount of antibodies in the body is adequate high to detected a test fitting.
Antigens test. Antigen tests have the purpose of detecting p24, a protein that is derived from HIV virus. Antigen tests can be executed 2-6 weeks after the patient is infected.



When screening shows the patient is infected with HIV (HIV positive), then the patient is undergoing a subsequent test. In addition to ensuring the screening results, the test can help the doctor clear the infection steps suffered, and also choose the appropriate treatment method. Just like screening, this test is carried out by taking over the blood samples of the patient, to be examined in the laboratory. Some of these tests include:

Count CD4 cells. CD4 is a member derived from the white blood cells destroyed by HIV. Therefore, there is a slight amount of CD4, so perhaps a person is attacked by AIDS. Under normal circumstances, CD4 counts are in the range of 500-1400 cells per cubic millimetre of blood. HIV infection develops into AIDS such as the result of the CD4 cell calculation below 200 cells per cubic millimeter of blood.
Viral load test (HIV RNA). Viral load tests have a purpose to calculate RNA, a member derived from a doubling HIV virus that benefits themselves. The amount of RNA more than 100,000 copies per milliliter of blood, a sign of HIV infection has recently occurred or is not handled. While the amount of RNA under 10,000 copies per milliliter of blood, indicates a viral growth that is not too fast. However, the condition always triggers the damage slowly against the immune process.
Resistance tests (immunity) to the drug. Some HIV subtypes are known to be immune to anti-HIV drugs. Through this test, doctors can select the style of anti HIV medication that is suitable for patients.
