Leukocyte LDL Cholesterol alkaline phosphatase (LAP) activity in the neutrophils varies widely in activity in different Lead hematological and non-hematological disorders, and may be helpful diagnostically. Lecithin Sphingomyelin Ratio Legionella Direct Fluorescent Antibody Assessment of LAP activity in the neutrophils is most useful in differentiating chronic myeloid Legionella Tests leukemia (CML), where it is typically decreased, from granulocytic leukemoid reactions, where Leukemia Lymphoma Panel by Flow it is typically increased. In CML, about 90% of cases show decreased LAP activity. When theCytometry disease is in remission, the LAP score may become normal; when CML is in blast crisis, LAP Leukocyte Alkaline Phosphatase activity is often normal or increased. Leukocyte Antibody Leukocytosis and Thrombosis LAP activity in the neutrophils is usually increased in polycythemia vera, whereas it is normal in Lipase secondary polycythemia. The LAP score is variable in the other myeloproliferative disorders Lipid Panel such as essential thrombocythemia and agnogenic myeloid metaplasia. Lipid Variability Lipoprint LDL Subfractions Low LAP activity is not unique to CML, but may also be found in diseases such as paroxysmal Lipoprotein a Cholesterol nocturnal hemoglobinuria (PNH), sickle cell anemia and sideroblastic anemia. High LAP activity Lithium is frequently seen in bacterial infections, pregnancy, and in patients receiving corticosteroids. Lupus Anticoagulant Panel Luteinizing Hormone Reference value is 20 - 137. Lyme Disease Serology Specimen requirement is one 10 mL green top (heparin) tube or 4 well made peripheral blood smears. All slides should be air-dried, unfixed, and unstained.
