Brief summary

To test blood samples from volunteer donors of whole blood and blood components using a new investigational test that detects human immunodeficiency virus (HIV) infection. Results will be compared to the current HIV screening assay.

Interventions

DEVICEcollection of follow-up sample based on PRISM HIV O Plus result

Test blood samples with investigational HIV assay. If results are reactive, donors may be deferred and asked to return for a follow-up blood draw.

PRISM HIV O Plus Test Data for Specificity12 monthsNegative HIV status was determined by the results of the HIV-1/HIV-2 comparator assay and HIV-1 qualitatitve RNA.
PRISM HIV O Plus Test Data for Sensitivity12 monthsFinal HIV status was determined according to a supplemental testing algorithm for specimens positive by the investigational assay. Supplemental testing involved HIV-1 Western blot, HIV-2 EIA, HIV-2 Western blot and HIV-1 ribonucleic acid (RNA).

Recruitment details

21606 donors enrolled from 6 geographically distinct blood donor and 1 plasmapheresis center. All donors were eligible if they signed a study consent form. In addition, 1388 specimens positive for HIV antibodies and 1117 specimens from US individuals at increased risk of HIV infection or from an HIV-2 endemic area.

Pre-assignment details

All subjects were assigned to one group. There was no pre-screening criteria specific for this study.

Outcome results

Primary

PRISM HIV O Plus Test Data for Sensitivity

Final HIV status was determined according to a supplemental testing algorithm for specimens positive by the investigational assay. Supplemental testing involved HIV-1 Western blot, HIV-2 EIA, HIV-2 Western blot and HIV-1 ribonucleic acid (RNA).

Time frame: 12 months

Population: 1,388 specimens from individuals positive for HIV antibodies and 136 specimens positive by supplemental testing from US individuals at increased risk of HIV infection or from an HIV-2 endemic area. These 1,524 specimens were used for the sensitivity calculation.
