Large red blood cell with basophilic stippling (between the two lymphocytes) in a case of auto-immune haemolytic anaemia (AIHA). To the right, next to the lower lymphocyte, there is a polychromatic red blood cell.

Red blood cells of a healthy individual showing a paler centre and a darker border. Occasionally the pale centre has an elongated shape (stomatocytes; at this frequency they have no pathological significance).

At the edge of a blood film normal red blood cells show no central pallor and look like spherocytes.

Trophozoites (rings) of Plasmodium falciparum are often thin and delicate, measuring on average 1/5 the diameter of the red blood cell. Rings may possess one or two chromatin dots. They may be found on the periphery of the RBC and multiple-infected RBC are not uncommon. Ring forms may become compact or pleomorphic, depending on the quality of the blood or if there is a delay in making smears.

Schistocytes (->) and thrombocytopenia in a patient with haemolytic uraemic syndrome (HUS). This disease, as well as for example thrombotic thrombocytopenic purpura (TTP), is a so-called 'microangiopathic haemolytic anaemia' (MAHA). Characteristic of MAHA is a responsive increase in the production of red blood cells and platelets whose immature precursors (reticulocytes and immature platelet fraction, IPF) can be measured on certain Sysmex analysers. On a blood film the differential diagnosis of MAHA is not possible.

Cell description:
Size: 12-15 µm
Nucleus: clumped chromatin and mostly divided into 2-5 distinct segments connected with filaments
Cytoplasm: acidophilic with many fine reddish granules spread evenly Function: phagocytosis, play an important role in the unspecific immune defense, in the tissue they defend the mucosa against bacteria and fungi
