I disagree with that logic. First of all, a 6.9 HGB is pretty low but if you function well on that, then that's ok. Most have a HGB threshold of 8 - 8.3. Once you hit that, you get transfused. What is your interval between red cell transfusions. Much depends on how much your bone marrow is producing.
Red cells live for 120 days. So I would venture to say that a portion of those transfused cells live longer than two weeks. It's also good to get the freshest blood product you can versus ones that are getting ready to expire within a few days.
John would get transfused at 8 and would get two units. The only time he got more than two was when his HGB was very low at 5.5.
