Blood donation

Why does the blood get thrown away?

I would like to know this also.

the blood is thrown away because they cannot use it. We ask this question too, it cannot to be reused

I am a member of another PV group. The same question has been asked several times.

Our blood is considered diseased due to the over production of various blood lines. We must never donate blood because the recipient can be contaminated with some of the factors that cause our disease. In some ways, what we have is a form of cancer. But unlike most cancers, we can manage it similar to diabetes.
