In general, 12 is adequate for surgery if attention to hemostasis is meticulous. This is dependent upon a host of factors including the amount of surgery performed, the cause of the anemia if present, and the treatment necessary to improve that anemia.

BBL can be performed for most individuals with a hemoglobin above 10 or 11.
