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.
