1. A method for classifying and counting white blood cells, comprising:
acquiring a first white blood cell histogram of white blood cells in a blood sample treated with a first hemolytic agent and a second white blood cell histogram of the white blood cells in the blood sample treated with a second hemolytic agent, wherein a ghost value in the second white blood cell histogram is less than a ghost value in the first white blood cell histogram, and the ghost value in the second white blood cell histogram is less than a ghost value threshold;
determining a peak type of the second white blood cell histogram;
performing white blood cell classification and counting based on the second white blood cell histogram when the peak type of the second white blood cell histogram is double-peak; and
performing white blood cell classification and counting by combining a classification result and a counting result of the second white blood cell histogram and a classification result of the first white blood cell histogram when the peak type of the second white blood cell histogram is single-peak.
