If you need to know which are the alkaline phosphatase (ALP) reference ranges or you require more information about the role of alkaline phosphatase (ALP) in the blood, you can visit normal alkaline phosphatase (ALP) level in the blood
Low alkaline phosphatase (ALP) in the blood is not common. It may be a consequence of a disease but the most usual reason is a low-protein diet or a zinc deficiency. If it occurs in children or adolescents is a matter of concern because it can cause growth disorders.
Mild hypophosphatasemia may be a consequence of a vegetarian diet with deficiency of proteins or zinc.
A vitamin C deficit (like occurs in scurvy) can lower the alkaline phosphatase (ALP) level in the blood. In the developed countries is not common to find this deficiency.
Hypothyroidism can be also a possibility. A visit to your doctor is advisable. He will study your medical record and he will decide if a thyroid function test is necessary. TSH level in the blood can be a help.

IMPORTANT: These levels are expressed in U/L. They are an example of a healthy man of about 45 years old with no known disease and not taking any medication. The ranges can be different depending on the laboratory or on your personal circumstances.
Normal ranges of alkaline phosphatase (ALP) in the blood in children and in pregnancy are very different at the values presented here. In that case you must use the respective reference tables.
