Alkaline phosphatase is usually not clinically low, and if low alkaline phosphatase occurs, it has no obvious significance. Alkaline phosphatase is an indicator of liver function. Alkaline phosphatase in the serum is mainly derived from the liver, bones, intestines and other parts of the body. the normal range is 45-125 U/L in adult males, 35-100 U/L in females 20-49 years old, and 50-135 U/L in females 50-79 years old. the reason for the different ranges may be due to the difference in degree of metabolism of bones in various age groups. Low alkaline phosphatase does not usually occur clinically, and if it does, it has no specific significance and is not a cause for undue concern. However, in the end stage of certain serious diseases, a lowering of the index may occur as the body fails. Low alkaline phosphatase alone does not require special treatment, but if it is accompanied by obvious symptoms and other abnormalities, you should go to the hospital in a timely manner, complete the relevant examinations to clarify the cause of the disease, and be treated under the guidance of a doctor.
