Introduction to Diagnosis of Liver, Gallbladder, and Biliary Disorders>
A variety of diagnostic tests help doctors assess disorders of the liver, gallbladder, and biliary tract (the ducts that connect the liver and gallbladder and that transport bile—see Overview of the Liver and Gallbladder). Among the most important are a group of blood tests known as liver function tests (see Liver Function Tests).
Depending on the suspected problem, a doctor may also order imaging tests, such as ultrasonography, computed tomography (CT), or cholangiography of the bile ducts using magnetic resonance imaging (MRI) or x-rays (see Imaging Tests of the Liver and Gallbladder). Also, a doctor may take a sample of liver tissue for examination under a microscope, a procedure called a liver biopsy (see Biopsy of the Liver).
