Figure.. Duffy Null Absolute Neutrophil Count Reference Range Compared With Current Institutional Reference Range
One hundred twenty Duffy null samples are represented in the histogram. The central 95% reference range for the Duffy null cohort is 1210/μL to 5390/μL. The overlying bell curve represents the current institutional central 95% reference range of 1900/μL to 7600/μL. There is a significant different between the Duffy reference median and the current reference median (2820/μL vs 4750/μL; P < .001).
