What are the storing conditions for white blood cells?

The optimal storing conditions for white blood cells involve keeping them at a temperature range of 2-25°C for up to 10 days. This temperature range helps to maintain the viability and functionality of the white blood cells, which are critical for various diagnostic tests and research purposes. Storing them within this temperature range minimizes stress on the cells, preserving their integrity and allowing for accurate analysis when they are later examined.

The other proposed conditions either suggest temperatures that are too low, which could impair cell viability, or denote ultra-cold storage, which is not suitable for white blood cells intended for usage in tests within a week. Therefore, maintaining white blood cells at the specified temperatures of 2-25°C effectively meets the requirements for proper storage without compromising their quality.
