What is the normal value of alkaline phosphatase in children?

As we all know, there are many kinds of enzymes in the human body, one of which is called serum alkaline phosphatase. When the human body's metabolism is abnormal, the serum alkaline phosphatase in the body will also become abnormal. For example, long back height and some other bone tissue diseases can also cause alkaline phosphatase to become abnormal. So for children, what should be the normal level of serum alkaline phosphatase in the body?

Normal values ​​of alkaline phosphatase in children:

When checking liver function, you will find an alkaline phosphatase indicator. Many parents take their children to do liver function tests, but they do not know the normal value of alkaline phosphatase in children, nor do they know what will happen if the alkaline phosphatase in children is too high. Next, we will introduce you to the relevant knowledge of alkaline phosphatase for your reference only.

What is alkaline phosphatase?

Alkaline phosphatase is an indicator of liver function test and is widely distributed in various organs of the human body, with the liver being the most abundant, followed by kidneys, bones, intestines, and placenta. When the liver is damaged or obstructed, bile enters the blood through the lymphatic tract and hepatic sinusoids. At the same time, due to the obstruction of bile excretion in the intrahepatic bile duct, bile refluxes into the blood, causing a significant increase in serum alkaline phosphatase.

What is the normal value of alkaline phosphatase in children?

Normal values ​​of alkaline phosphatase in children: less than 500U/L for 1-12 years old; less than 750U/L for 12-15 years old. Due to the relationship between alkaline phosphatase and bone and hepatobiliary system diseases, alkaline phosphatase values ​​are usually used as an important basis for the differentiation and diagnosis of these two diseases in clinical practice. However, children with high alkaline phosphatase levels are generally not considered a disease, because children's bone development process will secrete a large amount of alkaline phosphatase, which will lead to an increase in alkaline phosphatase in the blood. This is a normal physiological phenomenon.

What to do if children have high alkaline phosphatase

High alkaline phosphatase levels in children are mostly a sign of calcium deficiency. If only the blood and bone alkaline phosphatase index is high, while the blood phosphorus and blood calcium levels are also high or low, the possibility of calcium deficiency should be considered and combined with a physical examination of the child. It is recommended to check the baby's trace elements again. If the baby is confirmed to be calcium deficient, calcium supplements and cod liver oil should be supplemented in time, vitamin D and calcium supplements should be supplemented under the guidance of a doctor, and regular check-ups should be conducted. Iron deficiency should also be combined with physical examination results and iron supplements should be taken. Take your baby out to bask in the sun more often and add more calcium-rich foods.

In general, alkaline phosphatase is an indicator of liver function. For children, its value is different at different age stages. If a child's alkaline phosphatase level is too high, a specific analysis is needed. After all, there are many reasons why a child's alkaline phosphatase level is too high. Only by finding the cause can the child's alkaline phosphatase level be restored to normal.
