Thanks a lot for this detailed answer. It definitely clarified all my doubts and lifted the confusion in my head.

In fact, I completely forgot about the financial factor that may be by itself a showstopper (no matter the process is possible, almost impossible or impossible). I also forgot that for blood, room temperature is considered as cold. Yeah.... basic mistakes... but for my defense I am not working in healthcare.

Again, thanks a lot for our clarifications! I am almost feeling stupid with this very short answer to your very explanatory comment. ^^

Cheers, and have a great day!
