Definition (NCI_NCI-GLOSS) A type of immune cell that has granules (small particles) with enzymes that are released during infections, allergic reactions, and asthma. Neutrophils, eosinophils, and basophils are granulocytes. A granulocyte is a type of white blood cell.
Definition (NCI) A leucocyte with conspicuous cytoplasmic granules. In humans the granulocytes are also classified as polymorphonuclear leucocytes and are subdivided according to the staining properties of the granules into eosinophils, basophils and neutrophils.(On-line Medical Dictionary)
Definition (MSH) Leukocytes with abundant granules in the cytoplasm. They are divided into three groups according to the staining properties of the granules: neutrophilic, eosinophilic, and basophilic. Mature granulocytes are the NEUTROPHILS; EOSINOPHILS; and BASOPHILS.
Definition (CSP) leukocytes with abundant neutrophilic, eosinophilic or basophilic granules in the cytoplasm; mature granulocytes are the neutrophils, eosinophils, and basophils.

White Blood Cell Count procedure (C0023508)

Definition (NCI_CDISC) A measurement of the leukocytes in a biological specimen.
Definition (NCI) A test to determine the number of leukocytes in a sample of blood.
Definition (MSH) The number of WHITE BLOOD CELLS per unit volume in venous BLOOD. A differential leukocyte count measures the relative numbers of the different types of white cells.
Definition (CSP) number of white blood cells per unit volume in venous blood.

Leukocytes (C0023516)

Definition (MSHCZE) Bílá krvinka. Rozeznává se několik druhů, které se liší jak funkcí, tak místem vzniku a délkou života (neutrofily, eozinofily, bazofily, lymfocyty, monocyty). (cit. Velký lékařský slovník online, 2013 http://lekarske.slovniky.cz/ )
Definition (NCI) Blood cells that are devoid of hemoglobin, capable of ameboid motion and phagocytosis, and act as the principal components of the immune system.
Definition (NCI_NCI-GLOSS) A type of immune cell. Most leukocytes are made in the bone marrow and are found in the blood and lymph tissue. Leukocytes help the body fight infections and other diseases. Granulocytes, monocytes, and lymphocytes are leukocytes.
Definition (MSH) White blood cells. These include granular leukocytes (BASOPHILS; EOSINOPHILS; and NEUTROPHILS) as well as non-granular leukocytes (LYMPHOCYTES and MONOCYTES).
Definition (CSP) white blood cell, specifically a colorless cell with a nucleus, found in blood and lymph; leukocytes are capable of amoeboid movement; they can produce antibodies and move through the walls of vessels to migrate to sites of injury, where they isolate and destroy dead tissue, foreign protein and bacteria.
