Pre-albumin 197mg/L is less than the normal range of 280~360mg/L, which indicates malnutrition, viral hepatitis, cirrhosis and other diseases, and the situation is relatively serious.
1. Malnutrition: protein and other raw materials are needed for the synthesis of prealbumin by the liver, and protein intake will be reduced when malnutrition occurs, resulting in lower prealbumin.
2. Viral hepatitis: Hepatocytes are the main place for synthesizing prealbumin, when viral hepatitis occurs, the virus will destroy the hepatocytes and lead to the reduction of prealbumin synthesis, resulting in the reduction of the index.
3. Cirrhosis: the number and function of liver cells will decrease in cirrhosis, and the synthesis of prealbumin will also be affected, resulting in the decrease of prealbumin.
It should be noted that prealbumin cannot diagnose the disease alone, and should be combined with other related tests to confirm the diagnosis. If you have a low prealbumin, you should go to the hospital in time, combine the relevant examinations to identify the cause of the disease, and treat the symptoms under the guidance of the doctor.
