Lipaemic plasma: An objective non-invasive photometric method to classify plasma turbidity and its association with red cell haemolysis.

Background And Objectives: Plasma components are visually inspected, and non-transparent, turbid units are rejected for transfusion and fractionation. Additionally, in case a plasma component is deemed lipaemic, there is conflicting data on the accompanying red cell concentrate (RCC) in vitro quality. As visual inspection of plasma turbidity is a subjective method, we aimed to devise an objective measurement using a quick, non-invasive, table-top spectrophotometry-based method.

The effect of near-infrared low-level light on the in vitro quality of platelets during storage.

Background And Objectives: Near-infrared (NIR) light has been successfully applied to improve the quality of mouse platelets during storage. Because it is suspected that the mitochondria contain the primary photon acceptor, we hypothesized that human platelets for transfusion may be affected similarly and could benefit from NIR light treatment.

Materials And Methods: The optimal light dose was determined using portions of platelet concentrates (PCs) in PAS-E.
