EF>35% normal. A gallbladder ejection fraction of greater than 35% is considered normal.
Yes. Certain institutions use different cut offs for normal but usually Gallbladder ejection fraction greater than 35% is considered normal. People have discussed hyper dynamic gallbladder function but to my knowledge there is no upper limit of normal beyond which function is considered abnormally high.
Hyperkinetic gb. Most physicians in nuclear medicine and gastroenterology believe that increased ejection fraction of gall bladder is probably normal (above 35%). A well known nuclear physician reported small group of patients with hyperkinetic gall bladder (above 80% ejection fraction) getting relief with removal of gb. More studies needed to convince most surgeons.
