    Rotem Industries rotational thromboelastometry-extrinsic screening test (rotem-extem)
    <t>Viscoelastic</t> measures in nonleukoreduced and leukoreduced WB units over time. This figure shows viscoelastic measures of non-LR (blue bars) and LR (green bars) whole blood units over 15 days. These include the MCF measured by ROTEM (A), MA measured by TEG (B), TEG MA-ADP (C), and TEG MA-AA (D). Median measurements of MCF, TEG MA, TEG MA-ADP, and TEG MA-AA were compared at each time point between LR and non-LR groups, and absolute median measurements were compared from Day 0 to Day 15 within LR or non-LR groups. Differences are indicated by *p < 0.05, **p < 0.01, ***p < 0.001.

    Viscoelastic measures in nonleukoreduced and leukoreduced WB units over time. This figure shows viscoelastic measures of non-LR (blue bars) and LR (green bars) whole blood units over 15 days. These include the MCF measured by ROTEM (A), MA measured by TEG (B), TEG MA-ADP (C), and TEG MA-AA (D). Median measurements of MCF, TEG MA, TEG MA-ADP, and TEG MA-AA were compared at each time point between LR and non-LR groups, and absolute median measurements were compared from Day 0 to Day 15 within LR or non-LR groups. Differences are indicated by *p < 0.05, **p < 0.01, ***p < 0.001.

    Techniques Used:

    Viscoelastic measures in leukoreduced WB units by agitation method over time. This figure shows viscoelastic measures of LR WB units by differing agitation method over 15 days. Agitation methods included un-rocked (blue bar; none), up and down shake (green bar), continuous mechanical horizontal agitation via flat rocker (yellow bar), or continuous end-over-end rocking via a 360° rotator (red). The viscoelastic parameters measured include the MCF measured by ROTEM (A), MA measured by TEG, (B), TEG MA-ADP (C), and TEG MA-AA (D). Median measurements of MCF, TEG-MA, TEG MA-ADP, and TEG MA-AA were compared at each time point. No differences were noted. Median measurements of MCF, TEG-MA, TEG MA-ADP, and TEG MA-AA were compared within each agitation group from Day 0 to Day 15. Differences are indicated by *p < 0.05, **p < 0.01, ***p < 0.001.
