What is the recommended storage temperature for blood samples prior to analysis?

The recommended storage temperature for blood samples prior to analysis is 2-8 degrees Celsius. This temperature range helps to preserve the integrity and viability of the blood components, including cells and various analytes, for accurate testing. Maintaining blood samples within this specific temperature range minimizes metabolic activity and the risk of degradation or hemolysis, which could compromise test results.

Storing samples at room temperature could lead to changes in blood composition due to bacterial growth or cellular metabolism. Similarly, temperatures below freezing can cause cellular lysis, while conditions above 25 degrees Celsius may accelerate degradation processes or alter the stability of certain components. Therefore, adherence to the 2-8 degrees Celsius guideline ensures optimal conditions for accurate laboratory analysis.
