Alkaline phosphatase, one of the indicators of liver function, is slightly low at 45.3 U/L and is not a cause for special concern.
The main clinical causes of low alkaline phosphatase (including but not limited to the following categories):
1. Anemia of various etiologies, which in turn leads to low alkaline phosphatase, is common in adolescents/children; the more severe the anemia, the lower the alkaline phosphatase.
2. Viral infections can occasionally cause a decrease in alkaline phosphatase.
3. Some kidney diseases can cause low alkaline phosphatase.
4. Low thyroid function in children can cause low alkaline phosphatase and needs attention.
5. Other diseases: malnutrition, scurvy (vitamin C deficiency), hypoproteinemia (hereditary), malignancy due to tumors, etc.
If there is a history of any of the above diseases, or some obvious discomfort symptoms, it is recommended to have a review in the hospital.
