| DESCRIPTION | Displays cumulative data from the Bull algorithm. This is aHematology Quality Control option which allows the HematologySupervisor to monitor the MCH, MCV, and MCHC hematology indices.These indices are grouped in "sets" of 20 values, from which the mean and delta values are calculated. It has been reported thatthese three indices do not vary except in extreme disease states.Hence, the indices are an indication of the stability and precisionof the automated hematology instrument. Before using this optionthe original article by Dr. Brian Bull should be studied. |
