<p>Red blood cells showing hypochromia, anisocytosis and poikilocytosis.</p>
<p>Polychromatic red blood cell (arrow). With immature red blood cells or deficient haemoglobin synthesis the red colour of haemoglobin and the blue staining of RNA become mixed to produce a polychromatic appearance. As the red blood cell matures and its haemoglobin content increases it appears more red.</p>
<p>Small lymphocyte with slightly rough chromatin which stains dark purple. Purple azurophilic granules are present in the narrow band of cytoplasm. </p>
<p>Typical monocyte with greyish cytoplasm and a frosted-glass appearance. The nucleus shows the characteristic narrowing.</p>
<p>Two lymphocytes in the centre, adjacent eosinophil to the right and neutrophil below.</p>
<p>Blood smear of an aged rat (17-month-old) showing a picture of severe anaemia. In the centre, there is a neutrophil showing an atypically shaped nucleus, likely as a result of abnormal cell division.</p>
<p>Atypical lymphocyte of a rat with intensely blue cytoplasm and large size. </p>
<p>Band neutrophil with a doughnut-shaped nucleus and uneven surface. </p>
