<p>Lymphocyte on top of a monocyte. Note the different colour shades of the cytoplasm as well as different shapes of the nucleus.</p>

<p>Small lymphocyte in the upper left, monocyte in the centre, neutrophil in the lower left of the high-power field. Mild platelet aggregation.</p>

<p>Both cells are typical lymphocytes. Rat lymphocytes may have either wide or narrow areas of cytoplasm and occur in various sizes.</p>

<p>Metamyelocyte with a smooth, doughnut-shaped nucleus and bluish cytoplasm. Metamyelocytes are usually not found in the peripheral blood of rats. This blood smear is of an aged animal showing a picture of anaemia.</p>

<p>Rat monocyte with distinctive characteristics such as the colour shade of the cytoplasm and presence of vacuoles. The nucleus has a sharp notch.</p>

<p>Rat neutrophils have pale cytoplasm with fine, diffuse granules. The nucleus is highly segmented, coiled, or ribbon-like with numerous indentations. This cell’s doughnut-shaped nucleus is folded.</p>

<p>Blood smear with target cells, hypo- and polychromasia. </p>

<p>Anisocytosis, hypo- and polychromasia. In the centre, there is a neutrophil with a hypersegmented nucleus of which each segment is round – an atypical finding.</p>
