ABSTRACT:
Provided are automated methods for distinguishing and differentiating cells in a whole blood sample. In one of the methods, a whole blood sample is provided. One or more tests to be performed on the whole blood sample is selected. The tests to be performed on the whole blood sample are correlated. A volume of the whole blood sample is aspirated into an automated instrument system which automatically performs conventional hematology analysis and fluorescent cytometry analysis on the whole blood sample. A first aliquot of the whole blood sample is dispensed into at least one sample receiving vessel. The first aliquot of the whole blood sample is mixed with a fluorescent reagent. The first aliquot of the whole blood sample mixed with fluorescent reagent is diluted and transported through a flow transducer system. The flow transducer system detects multi-angle light scatter and fluorescence from the first aliquot of the whole blood sample mixed with fluorescent reagent and counts and differentiates platelets or platelet clumps or both in the sample. Detecting and differentiation data for the one or more tests performed on the whole blood sample are stored. Results of the one or more tests performed on the whole blood sample are reported in a quantitative manner if so requested. The instrument system automatically performs all method steps without physically separating cells from the whole blood sample or an aliquot of the sample and results of a conventional hematology analysis may be utilized in at least reporting of results of the fluorescent cytometry testing.
