How is blood stored and what temperature is required?

Blood is typically stored at a temperature range of 1-6°C. This temperature range is crucial for maintaining the viability of red blood cells and preventing bacterial growth. Storing blood within these parameters ensures that the cellular components remain functional and that the blood can be safely transfused to patients when needed.

When blood is stored at temperatures higher than 6°C, such as room temperature or 37°C, there is an increased risk of hemolysis (destruction of red blood cells) and potential bacterial contamination, both of which can compromise the safety of blood products for transfusion. Storing blood at -20°C is also inappropriate for whole blood or components like red blood cells, as this can lead to ice crystal formation, damaging the cellular integrity.

Thus, maintaining blood storage at 1-6°C is vital for preserving its components effectively, ensuring patient safety during transfusions.
