Hi Rachel, Sometimes they include platelets and sometimes they don't. Usually the numbers we collect pertain to patients using 3 or more blood products a day, so if a patient only uses 1 platelet and 1 whole blood unit, we don't track it like we do patients that use a heavy amount. Daily usage at the hospital is normal but most of my numbers are based off of patients who use three or more units. It's hard to get an exact amount because sometimes the units can be divided up in to smaller units so I try to get the numbers as accurate as possible. Basically the number of units you see is the minimum. The actual used units is higher during the week. Thanks for donating!
