Large erythrocyte with basophile stippling (between the two lymphocytes) in a case of autoimmune haemolytic anaemia (AIHA). To the right, next to the lower lymphocytes, there is a polychromatic erythrocyte.
Reticulocyte staining. Characteristic HbH cell in a case of α-thalassaemia. Today, blood films are no longer investigated for HbH cells. Instead, α-thalassaemias are diagnosed by molecular genetic tests.
