How long can frozen blood cells be preserved at -65 degrees Celsius?

Frozen blood cells can be preserved for an extended period at -65 degrees Celsius due to the low temperatures that significantly slow down biochemical processes, preventing cellular degradation and loss of functionality. Storing blood cells at this temperature allows for long-term preservation while maintaining the integrity of the cells.

Research and guidelines suggest that red blood cells can be stored for up to 10 years when frozen at -65 degrees Celsius or lower, provided that proper freezing techniques and storage conditions are strictly followed. This long shelf life is critical in various medical settings, including blood banks, where access to viable blood products is essential for patient care, especially in scenarios involving blood transfusions and for use in surgeries.

The other options reflect shorter preservation times that do not align with established guidelines for maintaining the viability of frozen blood cells at this low temperature. Knowing the specific storage guidelines is crucial for laboratory professionals, to ensure the optimal use of blood products.
