Whether chronic hepatitis is serious or not can be quickly judged by the following laboratory indicators: First, liver function test: if the liver function of jaundice index or transaminase index is elevated, especially the jaundice index is more than five times larger than the normal value, or the transaminase index is more than ten times larger than the normal value, it means that the condition is more serious. Coagulation time: liver is an important organ for synthesizing blood clotting factors, when liver function is seriously damaged, it will affect the synthesis of blood clotting factors. Therefore, when the clotting time is prolonged for more than three seconds compared with the normal value, it indicates that the liver function is seriously damaged. Liver ultrasound: if the ultrasound suggests the formation of cirrhosis, it also indicates that the condition is more serious.
