The differential was as follows:
| Cell Type | Patient Results | Reference Range |
| Blasts | 5 | 0 |
| Promyelocytes | 0 | 0 |
| Myelocytes | 1 | 0 |
| Metamyelocytes | 0 | 0 |
| Bands | 4 | 2–6 |
| Neutrophils | 63 | 5–70 |
| Eosinophils | 1 | 0–4 |
| Basophils | 0 | 0–2 |
| Lymphocytes | 22 | 20–44 |
| Monocytes | 4 | 2–9 |
Notes on the differential:
- Occasional hypogranulation of the neutrophils
- A few neutrophils with pseudo-Pelger-Huët
- Macrocytosis
- Anisocytosis
- Poikilocytosis
- Occasional basophilic stippling
The image to the right shows a hypogranular neutrophil with a pseudo-Pelger-Huët nucleus (bi-lobed nucleus). Both of these cell abnormal white blood cell findings can be seen in an MDS called MDS-EB2, which will be discussed on the next pages.
