CML is characterized by the presence of this chromosome
Philadelphia chromosome
t(9;22) gene product
BCR-ABL1 fusion gene (contained in the Philadelphia chromosome)
The presence of the Philadelphia (Ph1) chromosome signifies a good/bad prognosis?
Good prognosis
Used to differentiate Leukemoid reaction from CML
LAP/ NAP test (Leukocyte neutrophil alkaline phosphatase test)
Leukemoid reaction frequently refers to this type of cell
Neutrophils
The method utilized for the LAP test
