If you are referring to the practice of not using blood with overly
high hemoglobin levels, as occurs in such diseases as hemachromatosis
and polycythemia, this is justified on two grounds: first, the blood
is too thick and can not be directly transfused, Two, high hematocrit
can be indicative of a diseased state, thus the risks of using it for
transfusion can't be justified. Low hemoglobin levels are similarly
undesirable, and drawing blood could put the donor at risk.
Or are you talking about something else?
