Washing of platelets can be fully automated using a closed-system cell processor and BRS-A platelet additive solution

This study evaluated the in vitro properties of platelets (PLTs) washed with BRS-A additive solution in the Haemonetics ACP215 automated processing system. Two washing modes, 'manually/automatically adding ACD-A to BRS before/during the washing process', represented the control and test groups, respectively. Outcomes were compared over 7 days of storage (n = 7, for both). PLT recovery following washing processing (26-27 min) was 86·2 ± 1·7% and 86·0 ± 2·2% and plasma protein removal was 98·8 ± 0·3% and 99·0 ± 0·2% in the control and test groups, respectively (not significant). Both groups exhibited comparable in vitro properties.
