"Platelet concentrate, among other blood components, is considered an inventory management challenge due to its short shelf life. This study showed that extending platelet concentrate storage is possible for up to seven days without any chemical or microbial changes. Extending storage time for platelet concentrate will save money, increase availability, and save more patients. Further studies are required to evaluate platelet function during expiry time and to assess the stability of platelet morphology and function.
It is recommended that platelet concentrate storage time be extended to day seven after obtaining approval from the medical director in case of shortages or high demands. However, further studies must confirm these findings and determine the most effective strategies for improving platelet concentrate quality. Additionally, it would be ideal to investigate the clinical implications of these findings."
