I know what you're talking about. Kaplan will ask you about neutrophils in absolute (though they're guide doesn't give you that number). To calculate the range, think of Neutrophil percentage and absolute WBC range. Multiply neutrophil's lowest normal percentage by WBC lowest normal percentage and you'll have the Neutrophil lower limit (0.55*4,600), and again for the upper limit (0.75*11,000). There you go.
