摘要： Instances of the present technology may include a method for operating a hematology analyzer. The method may include passing a control material through a hematology analyzer. The control material may include a first cell population and a second cell population. The method may also include determining a first cell population volume measurement and a second cell population volume measurement. A first value of a first cell population distribution width and a second value of a second cell population distribution width may be calculated. The method may include comparing the first value to a first reference range. The method may also include comparing the second value to a second reference range. Furthermore, the method may include classifying an operational status of the hematology analyzer based on the comparison of the first value to the first reference range and based on the comparison of the second value to the second reference range.
