What distinguishes the major types of leucocytosis mentioned in the text?
Leucocyte concentrations and associations with other laboratory data

Bone marrow is unable to maintain an adequate response
What is a characteristic of toxic change in neutrophils?
Dysmature neutrophils released due to overwhelming demand
What does a regenerative left shift indicate?
An adequate response
What is a key characteristic of leukemoid reaction?
Marked leucocytosis that mimics neoplasia
