- Case Study One
- The neutrophils illustrated in this image are representative of those seen in a female patient's peripheral blood smear. The total WBC was 28.5 X 109/...
- Toxic granulation noted in the neutrophils' cytoplasm reflects an increase in activity of which of the following? (Choose all that apply)
- A peripheral blood smear with many myeloid cells was presented for morphology review (see image on the right). Toxic granulation and vacuoles in the n...
- The association of increased platelets accompanying neutrophilia and toxic granulation, as illustrated in this image, is called thrombocytopenia.

- A peripheral blood smear was reviewed and a representative field is shown on the right. Which of the following conditions may produce the results seen...
- Which of the following conditions is NOT associated with an increase in the white blood cell shown in the image on the right?
- Non Granulocytic White Blood Cells
- Giant Platelets
- Platelet satellites (see image to the right) may account for low platelet counts as determined by automated hematology cell counters. Satellitosis is ...
- The image on the right is a microscopic field from a Wright-Giemsa stained peripheral blood smear (1000X magnification). The structure indicated by th...
- A representative field from a peripheral blood smear, seen on the right, was held for morphological and clinical review as the total platelet count wa...
- The peripheral blood smear shown in this image was held for review because of an increased platelet count. Conditions in which platelets are increased...
- This image is representative of a peripheral blood smear. As a result of this phenomenon, some automated hematology analyzers may report:
