Usage: medical/hematology term; typically found in bone marrow; presence in blood may indicate disease or infection

Examples

• The laboratory technician identified myelocytes in the bone marrow biopsy sample.
• An elevated myelocyte count in the bloodstream can indicate leukemia or severe infection.
• During normal hematopoiesis, myelocytes mature into band cells and then segmented neutrophils.
• The pathologist noted the presence of myelocytes in the patient's peripheral blood smear.
• Myelocytes are characterized by a round to oval nucleus and cytoplasmic granules.
