A blood smear allows for the detailed visualization of different blood cells: - Red Blood Cells (RBCs): Normal RBCs appear as biconcave discs and should be uniform in size and shape. Variations may indicate conditions like anemia or spherocytosis. - White Blood Cells (WBCs): These cells are categorized into granulocytes (neutrophils, eosinophils, basophils) and agranulocytes (lymphocytes, monocytes). Abnormalities can suggest infections, inflammation, or leukemia. - Platelets: Small, disc-shaped cell fragments involved in clotting. An abnormal count or morphology can indicate bleeding disorders or bone marrow issues.
