Besides taking personal history and physical examination, abdominal ultrasound(U.S.) is the most common diagnostic test to check for gallstones. This examination is fast, painless, cheap, very accurate and can be done on an outpatient basis.
Other common diagnostic tests include blood tests, such as:
- Complete blood count
- Liver function tests, including total/direct bilirubin and serum amylase
- Coagulation profile
In cases of jaundice, other more complicated tests may be required, including Endoscopic Retrograde CholangioPancreatography(E.R.C.P.) or Magnetic Resonance CholangioPancreatography(M.R.C.P.).
