Checking whether there is any problem with the liver can be determined by liver function tests, imaging tests, and pathologic tests. 1. Liver function test: Liver function test includes bilirubin, albumin, globulin, glutamine transaminase, aspartyl transpeptidase and so on. This test can detect and diagnose acute and chronic hepatitis, liver fibrosis, cirrhosis, liver cancer and other diseases. If bilirubin and aminotransferase are elevated, liver function is abnormal and further examination is needed. 2. Imaging examination: checking whether there is any problem with the liver can also be combined with CT, MRI and ultrasonography to determine whether there is any space-occupying lesion in the liver, which is of high reference value for the diagnosis of hepatic hemangioma, cirrhosis and other diseases. 3. Pathological examination: If necessary, liver tissue biopsy can be performed. By taking liver tissue for pathological examination, it can be used to confirm the diagnosis of cirrhosis, liver cancer and other diseases. If you need to examine the liver, it is recommended to do so under the guidance of a doctor and make good preparations before the examination, so as not to affect the examination results.
