A left shift is characterized by an increase in which cells?

Explanation:
Left shift describes an increase in immature neutrophils in the peripheral blood, typically band neutrophils, indicating the bone marrow is releasing cells before full maturation to meet a high inflammatory or infectious demand. This reflects a rapid, reactive bone marrow response to infection or inflammation. Other cell types mentioned don’t define a left shift: lymphocytes rise for different immune scenarios (often viral or chronic conditions), platelets can increase with inflammation but not due to neutrophil maturation, and eosinophils rise in allergic or parasitic contexts.
