There are more indicators to look for in a hepatitis B patient, which can be divided into several areas. The first way to see if there is hepatitis B is through the first of the five hepatitis B items, called the surface antigen of hepatitis B. If the surface antigen is positive, it means that the patient is a hepatitis B patient; if the surface antigen is negative, it means that the patient is probably not a hepatitis B patient at present. If you are a hepatitis B patient, the next thing to look at in the liver function is the glutamic aminotransferase and glutamic oxalacetic aminotransferase, if these two are normal, it means that the liver function is basically normal. If there is an elevation of gluteal alanine aminotransferase or glutamic oxalacetic aminotransferase, the liver cells are damaged, which means in the state of hepatitis B. The description of the ultrasound is mainly based on the first three sentences: the liver is normal in shape and size, the membrane is bright and the parenchyma is evenly echogenic, which is a normal description. In some patients with hepatitis B, the echogenicity in the parenchyma may be slightly thicker and stronger, which can be interpreted as normal. However, if the tegument is no longer neat and the size of the liver has shrunk, it is a sign of cirrhosis. In addition, if the fetoprotein is normal, it means that there is no sign of liver cancer and no significant regeneration of liver cells. In contrast, if there is a gradual increase in methemoglobin, accompanied by hyper-echoic nodules that can be found on liver ultrasound, be alert to the risk of liver cancer.
