Tests used to investigate for gallbladder disease include [[blood tests]] and [[medical imaging]]. A [[full blood count]] may reveal an increased white cell count suggestive of inflammation or infection. Tests such as [[bilirubin]] and [[liver function tests]] may reveal if there is inflammation linked to the biliary tree or gallbladder, and whether this is associated with inflammation of the liver, and a [[lipase]] or [[amylase]] may be elevated if there is [[pancreatitis]]. Bilirubin may rise when there is obstruction of the flow of bile. A [[CA 19-9]] level may be taken to investigate for cholangiocarcinoma.<ref name=DAVIDSONS2010 />

An [[ultrasound]] is often the first [[medical imaging]] test performed when gallbladder disease such as gallstones are suspected.<ref name=DAVIDSONS2010 /> An [[abdominal X-ray]] or [[CT scan]] is another form of imaging that may be used to examine the gallbladder and surrounding organs.<ref name=DAVIDSONS2010 /> Other imaging options include MRCP ([[magnetic resonance cholangiopancreatography]]), [[Endoscopic retrograde cholangiopancreatography|ERCP]] and percutaneous or intraoperative [[cholangiography]].<ref name=DAVIDSONS2010 /> A [[cholescintigraphy]] scan is a [[nuclear imaging]] procedure used to assess the condition of the gallbladder.<ref>{{cite web|title=HIDA scan - Overview|url=https://www.mayoclinic.org/tests-procedures/hida-scan/home/ovc-20200578|website=Mayo Clinic|access-date=18 October 2017|language=en}}</ref>
