Don't eat after 12: H.I.D.A. scans or those like them are gallbladder function tests. An ultrasound is usually used first line as screening for biliary dysfunction. If equivocal or normal and symptoms strongly suggest biliary dysfunction - then a nuclear functioning test is done to assess the gallbladder ejection fraction (EF). If abnormal the gallbladder is usually the source of the symptoms - and surgery is needed
