NCT03285295

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.

Study Arms (1)

Screening

EXPERIMENTAL

All subjects will be tested with at least one of the investigational Alinity s assays (Anti-HBc, Anti-HCV, HTLV I/II, Chagas, HBsAg, HBsAg Confirmatory, HIV Ag/Ab Combo) on Alinity s system.

Device: Alinity s HBsAg and Alinity s HBsAg Confirmatory AssayDevice: Alinity s HTLV I/II AssayDevice: Alinity s Anti-HCV AssayDevice: Alinity s HIV Ag/Ab Combo AssayDevice: Alinity s Anti-HBc AssayDevice: Alinity s Chagas Assay

Interventions

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.

Screening

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.

Screening

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.

Screening

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.

Screening

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.

Screening

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.

Eligibility Criteria

Age16 Years+
Sexall
Healthy VolunteersYes
Age GroupsChild (0-17), Adult (18-64), Older Adult (65+)

You may qualify if:

  • Healthy donors who consented to participate in the study.

You may not qualify if:

  • 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.
