Screening for HIV-1 and/or HIV-2 infection in asymptomatic patients
Diagnosis of HIV-1 and/or HIV-2 infection in symptomatic patients
Follow-up testing of individuals with reactive results from rapid HIV tests
|Test ID||Reporting Name||Available Separately||Always Performed|
|HIVDI||HIV-1/-2 Ab Differentiation, S||Yes||No|
|HV1WB||HIV-1 Ab Confirm by Western Blot, S||Yes||No|
|HIV2L||HIV-2 Ab Confirmation, S||Yes||No|
This test begins with HIV-1/-2 antigen and antibody screen by the chemiluminescence immunoassay method. If HIV-1/-2 screen result is reactive, then HIV-1/-2 antibody differentiation test (by membrane immunoconcentration method) is performed at an additional charge. Depending on the HIV-1 and HIV-2 antibody results of this differentiation test, subsequent reflex tests such as HIV-1 antibody confirmation by Western blot and HIV-2 antibody confirmation by line immunoassay will be performed when appropriate and at an additional charge.
