I have had a ctscan. hida scan and stress test all normal but still pain in middle chest.right side. is ef 89 normal for hida scan?

Yes: That is a normal ejection fraction for the gallbladder. I hope your physicians are able to find an effective treatment for you in their thorough evaluation.

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.
