CML Glossary ‘L’
LAP = leukocyte alkaline phosphatase: a chemical produced in high quantities in certain leukemias, but always low in chronic phase CML. A low serum LAP is thus used to support the diagnosis of CML.
LD (or LDH) = Lactate dehydrogenase = an enzyme produced by certain cell and tissue types. It is used to help diagnose CML “blast” phase, since blasts produce LDH in abnormally high quantities.
*Leukemia = cancer of the white blood cells. Leukemia literally means “white blood” (leukos = white).
*Leukocyte = white blood cell (leukos = white; cytos = cell in Greek). The main types of leukocytes are neutrophils, lymphocytes, monocytes, basophils, and eosinophils.
Lymph = abbreviation for lymphocyte
Lymphocyte = a type of white blood cell generally not involved in CML. Two main types of lymphocytes are B-cells and T-cells.
