Transaminase 54U/L is high, should first clarify the cause of high, such as late at night, fatigue and other physiological factors, generally do not need to take medication, such as hepatitis, cirrhosis and other diseases can take biphenyl dibenzoate. Aminotransferase is a basic indicator of liver function tests, including alanine aminotransferase and glutamine aminotransferase. The normal value of alanine aminotransferase and glutamine aminotransferase is 0~40U/L. When the aminotransferase reaches 54U/L, it belongs to high, which is mainly seen in the physiological factors such as staying up all night, laboring and other diseases that damage the liver cells, such as viral hepatitis, fatty liver, alcoholic liver, cirrhosis of the liver, hepatocellular carcinoma and so on. Therefore, bifidobacterium can be taken when pathologic factors cause transaminases of 54 U/L, but it should be noted that it is contraindicated in patients with cirrhosis. Adverse reactions such as mild nausea and rash may occur when bifidus is administered. It should be contraindicated for patients with cirrhosis, pregnant and lactating women, and those who are allergic to the product, and should be used with caution in the elderly and children. It should also be noted that if jaundice and deterioration of the patient’s condition occurs during the course of taking the drug, the drug should be discontinued. When patients have elevated aminotransferases, it is recommended to consult a doctor in time to identify the cause of the disease and carry out targeted treatment. It is recommended to consult a doctor in advance when using biphenyl dibenzoate and take it strictly according to the doctor’s instructions, not self-medication, so as not to delay or even aggravate the condition.
