Groups/Cohorts	Assigned Interventions
EIA Negative Blood donor specimens that tested non-reactive by previously licensed HTLV screening assay.	Other: CDPHL Algorithm Supplemental testing algorithm performed by the CDPHL.
EIA Repeat Reactive Blood donor specimens that tested repeat reactive by previously licensed HTLV screening assay, but are unconfirmed.	Other: CDPHL Algorithm Supplemental testing algorithm performed by the CDPHL.
Known Positive Blood donor specimens that tested repeat reactive with a licensed HTLV screening assay and have been confirmed through additional, unlicensed supplemental testing.	Other: CDPHL Algorithm Supplemental testing algorithm performed by the CDPHL.

Detailed Description:

This is a retrospective study designed to assess the validity and reproducibility of the MP Diagnostics IVD device, the HTLV Blot 2.4 (MP Blot), in various populations. The study will be conducted at three geographical distinct locations.

The validity of the MP Blot will be assessed by calculating the following:

Percent negative agreement with CDPHL Algorithm on 200 EIA negative specimens
Percent positive agreement with CDPHL Algorithm on 200 EIA repeat reactive specimens

The sensitivity of the MP Blot will be evaluated by testing 200 known positive specimens. The study will be performed using three product lots at three clinical sites.

The reproducibility of the MP Blot will be assessed by testing two replicates of a three member panel at three clinical testing sites with each of three lots of product over multiple days by three operators.
