Need more info: What type of gb scan did you have—gb scan or hida scan? What units were given with the 33? (%, ml, etc) were other results given with this one. Please provide more info or ask your doc or the radiologist to explain the results.

HIDA scan with EF: After initial feeling with a radiotracer, your gallbladder contraction was stimulated and the percentage of radiolabeled bile ejected from the gallbladder was measured as "ejection fraction" or ef.This is a measure of gallbladder contractility and thus funcnution. Generally efs are greater than 50%, and < than 35% is considered abnormal. Yours is on the limit and clinical correlation is important.

Gallbladder ejection: Gallbladder ejection is measured as a percentage of the volume ejected when stimulated ( with a cck injection or infusion) . Usually 35% or greater is considered normal. Talk to your md.

Borderline low value: Ejection fraction which assesses ability of gall bladder to contract. and amount of activity coming out of gall bladder. 33% is on lower end of normal value. Most labs use 35% as low end of normal. Low values indicate gall bladder disease which may cause symptoms.
Dr. Brian Wosnitzer

Gallbladder EF: Some institutions may use different cutoff values for normal gallbladder ejection fraction. Usually a normal gallbladder ejection fraction is greater than 35%. 33% is slightly below normal. Low gallbladder ejection fraction can be seen in biliary dyskinesia or chronic cholecystitis. Your EF should be correlated with your symptoms.
