    Thanks for this information. It is a common practice by clinicians in my country (Cameroon, Central Africa) to insist on red cell concentrates with a shelf life of not more than 5 days. I would be pleased to share this article during the next Hemovigilance committee meeting.

      We must be careful. If the test was conducted in controlled environment where subject RBC units were kept in the fridge that is under strict temperature control, the test may not be reflecting the reality. Fridge doors are opened many times during 35 days and some of the RBC units are taken out from fridge several times for compatibility test. In addition, you also have to take it in your consideration the temperature controlling practice at blood collection site, production site, blood bank, and the transportation between them. The “35 days rule” only applies when it is accompanied with strict temperature management rules and tools in the whole supply chain. In other words, 5-day shelf life could be scientifically more realistic decision based on the reality of blood handling depending on the environment you are in.
