Male children at 4 years old have ALP ranges between 149 and 369 international units per liter, 10-year-olds normally have 191 to 435 international units per liter, and 15-year-old boys range from 138 to 511 international units per liter of blood, according to Mayo Clinic. Girls at 4 years old usually have 169 to 372 international units per liter of ALP, 10-year-olds have 215 to 476 international units per liter, and 15-year-old girls have 75 to 274 international units per liter of blood. ALP is a protein found in all tissues of the human body but mostly in the liver, bones, placenta and the intestines.
Higher-than-normal levels of ALP may indicate a bile duct obstruction in the liver, certain bone conditions and rapid bone growth during puberty, notes WebMD. High levels of ALP in the liver may be caused by jaundice, liver disease, liver damage and medicines that may affect liver function. Bone conditions relating to ALP levels include cancer that has spread to the bones, Paget's disease and vitamin D deficiency.Learn more about Medical Ranges & Levels
KidsHealth says that a comprehensive metabolic panel includes tests for three liver enzymes: alanine aminotransferase, alkaline phosphatase and aspartate aminotransferase. Each enzyme has a different range for what is considered normal, according to MedlinePlus.Full Answer >
Because an elevated alkaline phosphatase, or ALP, level can be associated with different medical conditions like rickets, cirrhosis, hepatitis, bone cancer, Paget's disease, hyperparathyroidism and a deficiency in vitamin D, symptoms and treatment options are different and dependent on the specific cause, as noted by WebMD. The ALP test is performed by drawing blood to check the levels of the enzyme alkaline phosphatase, which is made in different organs of the body like the liver, bones, intestines and kidneys.Full Answer >
Causes of high alkaline phosphatase levels include bone conditions, biliary obstructions, leukemia and liver conditions, Medline Plus states. Alkaline phosphatase is an enzyme that comes from several sites across the body. Some physicians may perform this test on its own, or as part of liver screening procedures.Full Answer >
