Alkaline phosphatase 35 is mildly low and further tests are needed to rule out the presence of bone and hepatobiliary system disorders. If there is no such disease, no special treatment is needed. If the above diseases are present, treatment of the primary disease is needed. Alkaline phosphatase is widely distributed in tissues such as liver, bones, intestines, kidneys and placenta, etc. Alkaline phosphatase can be physiologically elevated during adolescence, which is normal and does not require special treatment. If the alkaline phosphatase in the blood is persistently low, obstructive jaundice is very unlikely; if the bilirubin in the blood gradually rises while the alkaline phosphatase continues to fall, it indicates that the condition is worsening. Clinically, elevated alkaline phosphatase can also be seen in a variety of diseases, such as biliary obstruction, liver failure, bone disease, hyperthyroidism, etc., which require complete examination to clarify the cause of the disease and treat the cause.
