An increased absolute neutrophil count is seen in infections, inflammatory disorders, cytokine therapy, and some myeloid neoplasms. Neutropenia can occur due to medications like chemotherapy, toxins, bone marrow replacement (e.g., metastatic tumors, granulomas), myelodysplastic syndromes, autoimmune, or congenital disorders. The severity of neutropenia generally indicates the patient’s infection risk.
