Unable to find gallbladder in ultrasound. is that bad?

Repeat study: Make sure you haven't had it removed (sometimes folks forget)! most commonly the gallbladder is contracted and repeating the exam (after 12 hours of fasting) is advised. A contracted gallbladder can occur in the setting of chronic cholecystitis. Sometimes the gallbladder is in a location that makes it hard for the technologist to find. Lastly, some people are born without them (very rare!).
