Which of the following is not a common finding in myeloproliferative neoplasms?

The technology used by most flow cytometers to identify, enumerate, and differentiate between white blood cells in a sample is called: 

Hydrodynamic focusing in flow cytometry is important because it:

In the absence of disease, the cells shown below are normally found in what pool?   

A patient’s blood smear shows many of the cells seen below along with a regenerative left shift, vacuolization and Dohle bodies.  What is the patient presumably suffering from based on these findings?   

An adult patient has a white blood count of 80 × 109/L. The differential has 92% Sudan black B–positive blasts and 8% lymphocytes. Which is most likely?

A 27-year-old woman presents with acute bleeding to the emergency department and is found to have a white count of 25.7 x 109L with pancytopenia: hematocrit 27%, platelet count 35 x 109/L, and absolute neutrophil count 0.8 x 109/L. Molecular analysis detects PML-RARA and Cytogenetics revealed t(15,17).  Her peripheral blood smear is below.  What is the most likely condition?  

A 15-year-old boy presents complaining of severe headaches; he has a white count of 76.0 x 109/L, platelet count of 55 x 109/L, and a hematocrit of 33%. When a white cell differential is performed, most of the nucleated cells are blasts. They are CD2, CD4, and CD8 positive. What is the most likely condition? 

Which nonmalignant alteration is associated with poor mucopolysaccharide processing and can be easily confused with toxic granulation? 

Cell dysfunction in the myelodysplastic syndromes may be present in:
