Although these tests can suggest that a patient has NAFLD—mainly by excluding other liver diseases and conditions (such as biliary tract disease and focal liver disease) that also can elevate levels of liver enzymes—they cannot give acute fatty liver of pregnancy a definitive diagnosis or determine the stage of the disease.33,47,48 The only way to confirm a diagnosis of NAFLD—and to gauge the severity of inflammation, fibrosis, or cirrhosis—is a liver biopsy,33,3,21 in which a needle is inserted into the liver to remove a sample of tissue that is then examined under a microscope. (In a fatty liver, numerous large round white sacs, or fat vacuoles, will be visible to the lab technician.) |

| Because NAFLD is usually asymptomatic, a doctor generally will first suspect NAFLD when reference liver function tests during routine blood work show that a patient’s liver enzymes (in particular, alanine aminotransferase, or ALT) are mildly to moderately elevated. Studies show that as many as 29% of reference adults fall into this category.43 But because people who do not have NAFLD may have elevated ALT levels, reference and because the disease also may be present whether or not a person has elevated enzyme levels44—NAFLD is found in as many as 30% of people with normal ALT levels45—further laboratory testing is always necessary. The next step in the diagnosis process usually is to screen the liver by ultrasound (sonography), which uses harmless sound waves to show images of the organ. When a large amount of fat has accumulated in the liver, it may show up as enlarged and will appear “brighter” than the kidneys on the ultrasound screen;46however, moderate amounts of fat may not be detected by an ultrasound screening. |
