How long can blood be stored at room temperature after collection?

Blood can be stored at room temperature for a limited period to maintain its viability and safety for transfusions. The correct duration for storing blood at room temperature after collection is up to 4 hours. This timeframe is critical because beyond this period, there is an increased risk of microbial growth and the deterioration of the blood components, which can lead to complications in transfusion recipients.

Different blood components, such as red blood cells, have specific guidelines regarding storage. While room temperature storage is sometimes permissible for certain processes (like transportation or short-term handling), the 4-hour limit is generally recognized to minimize potential risks. Blood banks and transfusion services adhere to this guideline to ensure the safety and effectiveness of the blood supply.
