Pathogen inactivation of red cell concentrates and whole blood: <scp>I</scp> . History, technologies and in vitro product preservation studies
Bibliographic record
Abstract
The application of technologies to inactivate pathogens in pooled plasma products is nowadays the standard. The number of blood centres applying these technologies to platelet concentrates is steadily increasing. However, pathogen inactivation (PI) of red cell concentrates and whole blood (WB) is challenging, as the haemoglobin-containing red cells quench light, and therefore require a different approach. Three technologies are currently under active development: S-303 (Intercept), UV-C (Theraflex) and riboflavin/UV (Mirasol). The S-303 technology is used for PI of red cell concentrates and has seen significant technical and clinical development in the last decade. Using this technology, red cell both ATP and haemolysis levels conform to objective requirements. For the UV-C technology, only one publication is available showing satisfactory quality of treated red cell concentrates in vitro. Lastly, the riboflavin and UV light technology is used on WB, and the in vitro data show room for improvement for red cell ATP and haemolysis levels. Part II of this review focuses on recovery studies and clinical trials that have been performed using pathogen-inactivated red cell concentrates.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
