How should blood samples be stored?

The proper storage of blood samples is crucial for maintaining their integrity and ensuring accurate test results. Storing blood samples refrigerated at temperatures between 2-8°C is recommended for most routine tests. This temperature range helps to slow down microbial growth and preserve the stability of the components within the blood, including cells and biochemical markers. By keeping the samples cool, it minimizes the risk of degradation or altering the composition of the sample prior to analysis.

Other temperature conditions, such as room temperature or freezing at -20°C, are generally not suitable for most blood samples, as they can cause changes to the sample's cellular and biochemical makeup. Exposing blood samples to light can also lead to degradation of light-sensitive components, making it vital to store them properly away from light sources. Hence, maintaining the specific refrigerated temperature is essential for accurate test outcomes.
