[Parameters for estimating abnormal reticulocyte specimens from blood cell counts]

In order to estimate reticulocyte levels, low, normal or high, parameters for discrimination are calculated using hematology count data. Multivariate discriminant functions were used for detecting abnormal reticulocyte specimens for computerized laboratories. The method detects 60.2%, 60.3% and 15.7% of low, high and normal reticulocyte specimens respectively. Discrimination method with individual test data are used for uncomputerized laboratories. The tests used for detecting abnormal reticulocyte specimens are white blood cells, red blood cells, mean cell hemoglobin concentration and red blood cell distribution width. Detection efficiencies for low, high and normal reticulocyte specimens are 55.9%, 50.4% and 14.7%.
