Brief summary

The objective of this study is to demonstrate the performance and intended use of each of the Alinity s investigational assays in a donor screening environment using clinical specimens to evaluate assay performance characteristics. A comparison of assay performance will be done versus the Food and Drug Administration (FDA) licensed assays. The data will be used to support regulatory submissions and/or publications.

Detailed description

This study evaluates Alinity s investigational assays using the Alinity s System. The Alinity s System is a high-volume, automated, blood-screening analyzer that is designed to determine the presence of specific antigens and antibodies by using chemiluminescent microparticle immunoassay (CMIA) detection technology. The system performs high-throughput routine and stat processing that features continuous access and automated retesting. The Alinity s System is used for infectious disease marker testing in blood-screening and plasma laboratories for the following assays: Anti-HBc, Anti-HCV, HTLV I/II, Chagas, HBsAg, HBsAg Confirmatory and HIV Ag/Ab Combo.

Interventions

DEVICEAlinity s HBsAg and Alinity s HBsAg Confirmatory Assay

For all donor specimens with investigational Alinity s HBsAg and Alinity s HBsAg Confirmatory results that are discordant with final status after supplemental testing, an attempt will be made to obtain a follow-up whole blood specimen approximately 4 to 6 weeks after initial donation for further analysis.

DEVICEAlinity s HTLV I/II Assay

For all donor specimens with investigational Alinity s HTLV I/II results that are discordant with final status after supplemental testing, an attempt will be made to obtain a follow-up whole blood specimen approximately 4 to 6 weeks after initial donation for further analysis.

DEVICEAlinity s Anti-HCV Assay

For all donor specimens with investigational Alinity s Anti-HCV results that are discordant with final status after supplemental testing, an attempt will be made to obtain a follow-up whole blood specimen approximately 4 to 6 weeks after initial donation for further analysis.

DEVICEAlinity s HIV Ag/Ab Combo Assay

For all donor specimens with investigational Alinity s HIV Ag/Ab Combo results that are discordant with final status after supplemental testing, an attempt will be made to obtain a follow-up whole blood specimen approximately 4 to 6 weeks after initial donation for further analysis.

DEVICEAlinity s Anti-HBc Assay

For all donor specimens with investigational Alinity s Anti-HBc results that are discordant with final status after supplemental testing, an attempt will be made to obtain a follow-up whole blood specimen approximately 4 to 6 weeks after initial donation for further analysis.

DEVICEAlinity s Chagas Assay

For all donor specimens with investigational Alinity s Chagas results that are discordant with final status after supplemental testing, an attempt will be made to obtain a follow-up whole blood specimen approximately 4 to 6 weeks after initial donation for further analysis.

Inclusion criteria

* Healthy donors who consented to participate in the study.

Exclusion criteria

* For testing with the Alinity s Chagas assay, exclude donors that have been screened on a previous donation using a licensed test for antibodies to T cruzi. Note: A subject may participate at different times during the study for separate assay studies, but each subject should be represented only once for each assay. The protocol does not define an age limit. A donor must be at least 17 years old to donate to the general blood supply, or 16 years old with parental/guardian consent, if allowed by state law.
