Disclaimer: This identifier is an educational decision-support aid for trained and training laboratory staff. Drawings are simplified diagrams. Photographs are real blood films from the Only Cells Photo Library (mostly May–Grünwald–Giemsa stain), with no patient details; some are shared by colleagues and credited to them. Each shows one patient and may not show every feature. Always confirm findings with an experienced colleague, follow your local SOPs and current national guidance, and escalate urgent findings (blasts, malaria and other parasites, abnormal promyelocytes, significant fragmentation) immediately.
