Alpha-L fucosidase 41.2 U/L is greater than normal but is mildly elevated. It may be caused by physiological factors or pathologic factors such as hepatitis and hepatocellular carcinoma. It is important to go to the hospital for timely examination to rule out pathologic factors. The normal value of α-L fucosidase is 3~40U/L. Both physiologic and pathologic factors may lead to elevated values of α-L fucosidase. Physiologic factors, such as pregnancy in women, can cause alpha-L fucosidase to be greater than normal, in which case it is not a problem and does not need to be treated. Pathological factors such as hepatitis and liver cancer can also lead to elevated α-L fucosidase. If accompanied by symptoms such as abdominal pain, fatigue, loss of appetite, etc., you should go to the hospital in time, complete the relevant examinations such as CT to clarify the cause of the disease, and carry out the treatment under the guidance of the doctor.
