How is an examination of the liver performed?

The liver is located in the abdomen but the health care professional will want to examine the whole body to look for the consequences of liver disease.

  • The abdomen may be palpated to feel for an enlarged liver. As it grows, the liver edge may be felt below the right rib margin. An inflamed liver in acute hepatitis may be tender but a liver that is cirrhotic, small and shrunken, may not be able to be felt.
  • If liver disease is a consideration, the health care professional also may feel for an enlarged spleen and assess whether excess fluid is present in the abdomen (ascites), perhaps indicating the presence of portal hypertension.
  • The skin, including the sclera of the eyes, may be assessed for color looking for jaundice. Spider nevi, or angiomata, are a collection of blood vessels under the skin and may be normal, but in the proper setting may indicate liver disease.
  • If the person is confused (hepatic encephalopathy), the doctor may attempt to illicit asterixis, or flap on the physical examination. These people may not be able to keep their wrists cocked when their arms are held outstretched but instead see their wrists rhythmically flapping.
  • Blood tests may be ordered to help make the diagnosis. Liver enzymes levels may reveal liver inflammation. However, in patients with end-stage liver disease, the liver can burn itself out and the enzymes may be normal even in the face of severe disease. Other blood tests that may be appropriate include a complete blood cell count (CBC), hepatitis virus screen, and blood clotting tests (a sensitive way to measure function since the liver is responsible for manufacturing the proteins involved in the blood clotting mechanism).
  • On occasion, ultrasound may be helpful in assessing the anatomy of the liver and this may lead to other tests including CT scan to further assess the anatomy and structure of the liver and surrounding tissues.
