What is the best short-term storage condition for liquid blood?

Refrigerated storage is the best short-term condition for liquid blood because it effectively slows down the metabolic processes and bacterial growth that can compromise the integrity of the blood sample. Typically, blood should be stored at a temperature between 2°C and 6°C (36°F and 43°F) for short periods, as this temperature range maintains the viability of blood cells and plasma components without causing cellular degradation or hemolysis.

Storing blood at elevated temperatures, such as room temperature, allows for faster deterioration. On the other hand, freezing blood causes ice crystal formation, which can rupture cell membranes and lead to irreversible damage to the sample. While temperature-controlled environments might provide stable conditions, they are not specifically designed or necessary for the short-term preservation of blood, making refrigerated storage the optimal choice in this context.
