neutrophils
What is the first line of defense against invasion of antigens?
neutrophils
What does a left shift neutrophilia suggest?
suggests acute inflammation
What is a right shift neutrophilia?
increase in the numbers of hypersegmented neutrophils
Why would a patient have neutropenia?
sudden demand, decrease in bone marrow production, viral diseases, transfusions, neoplasia
What are Eosinophils also called?
