Evaluation of Diagnostic HIV Ag/Ab Combo Assay

To test blood specimens using a new investigational test that detects antigen and antibody to human immunodeficiency virus (HIV). Results will be compared to an approved HIV antibody test and supplemental testing performed to determine HIV status.

All specimens collected under separate specimen collection protocols or obtained from specimen suppliers will be provided to the clinical sites performing the investigational HIV test. This includes 6252 specimens collected from normal healthy individuals (7B5-02-05Z01-01: Collection of Specimens Used in Abbott Laboratories In Vitro Diagnostic HIV and Hepatitis Assays Clinical Studies)and from specimen suppliers. 588 specimens from HIV-infected pediatric subjects and 448 pregnant females at risk for HIV infection collected under protocol (7B5-02-05Z01-02: Collection of Pediatric and Pregnant Female Specimens Used in the Abbott Laboratories In Vitro Diagnostic HIV Assay)and from specimen suppliers. All specimens were previously collected and frozen, except for a subset of 586 specimens from normal healthy population and 55 specimen from pregnant females at risk for HIV infection which were collected under separate specimen collection protocols and tested as fresh specimens during the study. In addition, 83 specimens that were HIV antigen positive, 1121 specimens that were HIV-1 antibody positive, 201 specimens that were HIV-2 antibody positive, and 1409 specimens from US at risk for HIV infection or from HIV-2 endemic area were all obtained from specimen suppliers, except for 11 pediatric specimens collected under a separate protocol (7B5-02-05Z01-02: Collection of Pediatric and Pregnant Female Specimens Used in the Abbott Laboratories In Vitro Diagnostic HIV Assay).

Specimens collected from normal apparently healthy individuals at low risk for HIV infection will be tested by the investigational HIV test and FDA-licensed HIV test.

Specimen with confirmed positive HIV Antigen, HIV-1 antibody, or HIV-2 antibody will be tested by the investigational HIV test.

Specimen collected from individuals at risk for HIV infection will be tested by the investigational HIV test.

Test blood samples with investigational HIV assay. If results for specimens from the normal healthy population or pregnant female population at risk for HIV infection are reactive, samples will be tested with supplemental HIV assays. If all supplemental HIV assays are negative, subject will be asked to return for a follow-up blood draw.

Test blood samples with investigational HIV assay. If results for specimens from the at risk population are reactive, samples will be tested with supplemental HIV assays. If all supplemental HIV assays are negative, subject will be asked to return for a follow-up blood draw when possible.

HIV status was determined by the results of the HIV comparator assay, HIV-1 Western blot, HIV-2 Western blot, and HIV-1 ribonucleic acid (RNA) test.

Positive HIV status was determined by the results of the HIV-1 Western blot, HIV-2 Western blot, and/or HIV-1 ribonucleic acid (RNA) test.

HIV status was determined by the results of the HIV comparator assay, HIV-1 Western blot, HIV-2 Western blot, and HIV-1 ribonucleic acid (RNA) test.

Architect HIV Combo Test Data for Specificity and Sensitivity in Pediatric Population (From 2 up to 21 Years of Age)

HIV status was determined by the results of the HIV comparator assay, HIV-1 Western blot, HIV-2 Western blot, and HIV-1 ribonucleic acid (RNA) test.

Architect HIV Combo Test Data for Reactivity of Architect HIV Combo in Increased HIV Risk Populations

Reactivity was determined by the results of the Architect HIV Ag/Ab Combo assay and supplemental testing by HIV-1 Western blot, HIV-2 Western blot, and HIV-1 ribonucleic acid (RNA) test.
