What is the preferred method of storing tubes before they are processed?

• A. Store them at room temperature
• B. Keep them in a freezer
• C. Refrigerate them immediately
• D. Leave them in direct sunlight

Answer: (A)

The preferred method of storing tubes before they are processed is to keep them at room temperature. This practice is important because most blood specimens are stable and can maintain their integrity at room temperature for a certain period before processing. Storing tubes at room temperature helps to avoid any potential changes in the composition of the blood sample that might occur under extreme conditions, such as freezing or refrigeration. In contrast, placing tubes in a freezer can cause the formation of ice crystals, which may damage the cells and interfere with test results. Refrigerating the samples immediately may also not be suitable for all types of tests, as some analytes can become unstable at lower temperatures, leading to inaccurate results. Leaving tubes in direct sunlight is also detrimental as it can cause temperature fluctuations and degrade certain components of the sample, affecting the accuracy of the tests being performed. Thus, maintaining the tubes at room temperature is the most reliable method for preserving their quality prior to processing.
