Overview
Leukocyte alkaline phosphatase is an enzyme found within white blood cells. The blood level of leukocyte alkaline phosphatase is measured in order to help in the diagnosis of certain conditions. Higher levels of the enzyme are seen in polycythemia vera, essential thrombocytosis, primary myelofibrosis and leukemoid reaction. Lower levels are found in chronic myelogenous leukemia, aplastic anemia, paroxysmal nocturnal hemoglobinuria and acute myelogenous leukemia.
Causes of Increased Leukocyte Alkaline Phosphatase
Common Causes
- Acute leukemia
- Essential thrombocytosis
- Leukemoid reaction
- Malignant lymphomas
- Megaloblastic anemia
- Multiple Myeloma[1]
- Myelofibrosis
- Polycythemia Vera
- Solid tumors
- Tissue necrosis[2][3]
