Physical examination, lab tests, and imaging tests are done to diagnose the gallstones. The doctor also asks about your diet to identify the reasons.
- Blood tests to check the level of bilirubin to determine the liver functioning
- Ultrasound of the abdomen and CT scan to analyze if the gallstones are present
- Endoplasmic Retrograde Cholangiopancreatography (ERCP) with the help of a small camera down to the gastrointestinal tract. This is done to check for the gallstone obstructing the bile duct.
