3 doctors agree
In brief: >35 %
A normal gallbladder ejection fraction is usually over 35%.
Anything less than this would be considered dysfunction of the gallbladder or biliary dyskinesia.

This test has a high incidence of FALSE-POSITIVES, meaning that as many as 25% of people with normal gallbladder function may have a decreased ejection fraction on this test. Therefore, it is wise to investigate other causes of pain before having surgery.

Agree with Dr. Rosen.

More than 50% normal, 36-49% is indeterminant, and 35% or less is abnormal.
