    Depends on the product.

    - PRBCS = 1 unit
    - Granulocytes = 1 unit
    - Platelet Pheresis = 1 unit
    - Platelets random donor - 6-9 units, varies
    - Cryoprecipitate = multiple units in a bag, marked on bag

    ML Amounts in blood bags vary widely, even within each category.

    Wow, I'm so glad I read this thread! I always just assumed one bag = one unit; it's good to know that apparently it varies by product, and how much you actually get out of it is different too! I learn so much stuff on AllNurses that we would never cover in school, it is amazing!
