Liver disease is a condition that occurs in the liver. It includes hepatitis B, hepatitis A, hepatitis C, cirrhosis, steatosis, hepatocellular carcinoma, alcoholic liver and many other liver diseases. It is a common and extremely dangerous disease that should be actively prevented. The manifestations of liver disease are very subtle, and the most prominent symptoms are fatigue and lack of appetite. Then what are the examination methods for liver disease? 1, Liver function test (GOT, GPT): When liver cells are necrotic, GOT and GPT are released into the blood only after the destruction of hepatocyte membranes (under normal circumstances, GOT and GPT exist not only in liver cells, but also in cells in other parts of the body, such as: muscle cells, brain cells, cardiac myocytes, etc., so the elevation of GOT and GPT is not necessarily a reflection of the impaired liver function, but only in the liver cells where their levels are highest). Therefore, some people think that it is more appropriate to call it an indicator of liver inflammation than an indicator of liver function. The level of GOT and GPT values is not related to the severity and prognosis of liver disease. Sometimes, the immune system causes necrosis of liver cells in order to clear the virus, and the GOT and GPT values will rise at this time, so we can’t judge whether the liver is in trouble with GOT and GPT alone. Hepatitis markers: When liver cells are necrotic, GOT, GPT will be released into the blood, therefore, some people think that it is more appropriate to call it “liver inflammation indicator” than liver function indicator. The level of GOT, GPT value is not related to the severity and prognosis of the liver disease. Sometimes the immune system causes necrosis of liver cells in order to clear the virus, and the GOT, GPT value will rise at this time, so we can’t judge whether the liver is in trouble with the GOT, GPT alone. 3.Abdominal ultrasound: Although blood test can reflect the condition of liver function of patients, it can not provide clear information about cirrhosis or liver cancer, especially for some patients with cirrhosis and liver cancer, the results of their liver function tests are sometimes within the normal range and they may not have any symptoms. Therefore, it is necessary to take blood test with ultrasound examination. 4. Blood test of alpha-fetoprotein (AFP/fetal protein): alpha-fetoprotein (AFP/fetal protein) is an important index for checking liver cancer, alpha-fetoprotein/AFP is a kind of manifestation of active growth of liver cells, so a small portion of normal people and women during pregnancy can have higher level of alpha-fetoprotein/AFP than normal people, and the growth of liver cells of fetus is active, and the alpha-fetoprotein/AFP secreted by fetus is higher than that of normal people (so it can be called fetal protein), and fetal protein is not only the most important indicator for checking liver cancer, but also the most important one. Fetal hepatocyte growth is active, its secretion of alpha-fetoprotein/AFP is significantly higher than that of normal people (so it can be called fetal protein), AFP can pass the placental barrier so that AFP is elevated in the mother’s blood, AFP can be elevated in the recovery period of some patients with hepatitis when hepatocyte growth is active, but the degree of elevation is generally milder or shorter in duration, when the elevation of alpha-fetoprotein/AFP is significantly or progressively elevated, then there is a possibility that it may be hepatocellular carcinoma, so pay attention to consulting with specialists, and go to the hospital for examination at an early stage.
