Are elevated ALT and AST levels indicative of hepatitis B?
During my most recent check-up, the report showed that my ALT and AST levels were elevated. I would like to ask, are elevated ALT and AST levels indicative of hepatitis B?
Doctor's answer (1)
Elevated ALT (alanine aminotransferase) and AST (aspartate aminotransferase) levels do not necessarily indicate hepatitis B infection. These are two important indicators in liver function tests. When the liver is damaged, these enzymes are released into the bloodstream, causing their levels to rise.
Hepatitis B virus infection is one possible cause of elevated ALT and AST levels, but there are many other contributing factors, including fatty liver disease, alcoholic liver disease, liver damage caused by medications or toxins, hepatitis viruses (such as hepatitis A or C), cirrhosis, liver cancer, and even certain non-liver-related conditions such as myocardial infarction or muscle injury may also affect enzyme levels.
To confirm whether hepatitis B is present, more specific blood tests are required, such as hepatitis B surface antigen, hepatitis B surface antibody, hepatitis B e antigen, and hepatitis B core antibody. If elevated ALT and AST levels are detected, it is important to consult a doctor.
