Within this section, specimens can be viewed from a range of disease states, categorized by their acute, chronic or reactive nature. If available, XN scatterplots and the immunophenotype of the abnormal population are also shown. A bar graph is shown with each specimen, indicating what types of cells were found and in what relationship to each other.

For clarity, only the most notable or aberrant cells are shown. These cells are marked blue in the bar graph. The example above shows an approximate normal ratio of leukocytes of an adult.

Where possible, slides from peripheral blood (PB) are complemented by images from bone marrow (BM, aspirate squash preparation) and immunophenotyping (IFT) scatterplots. The unavailability of material may be because there was no indication for a bone marrow puncture, because of a dry-tap or because the diagnostics were done in a non-participating centre.
