CBC measures red blood cells, white blood cells, and platelets. Blood sample is drawn from arm using sterile needle. No special preparation needed for routine CBC tests
Pegfilgrastim is a PEGylated form of filgrastim, developed by Amgen. It stimulates production of white blood cells (neutrophils). Has a half-life of 15-80 hours, longer than parent filgrastim
PMNs are white blood cells including neutrophils, eosinophils, basophils, and mast cells. They have variable-shaped nuclei with deep divisions. PMNs are part of innate immune system and first line of defense
WBC count test measures percentage and types of white blood cells in blood. Test involves simple blood draw from arm vein. Results typically available within few days
Granulocytes are white blood cells that appear granular under microscope. Immature granulocytes develop in bone marrow to form neutrophils, eosinophils, and basophils. Neutrophils are most common, accounting for up to 60% of white blood cells. Basophils release histamine and heparin, while mast cells aid in immune response
Leukocytes are white blood cells that function as anti-inflammatories. There are five types of leukocytes: neutrophils, eosinophils, basophils, lymphocytes, and monocytes. White blood cells are produced in bone marrow and circulate throughout the body. Normal blood contains between 3.4 and 8.2 billion white blood cells per litre
