Use of Mindray MC-80 digital morphology analyzer’s estimated platelet counts as adjunct to automated hematology analyzer

Introduction: Automated hematology analyzer platelet counts can be performed using either the impedance (PLT-I) method or fluorescent nucleic acid staining (PLT-O) method. Estimated (PLT-E) calculated a digital morphology by evaluating peripheral blood smear. Our objective was to compare values detected on Mindray BC-6200 device PLT-E count MC-80 analyzer. Material and methods: Complete cell findings between 1 September 11 October, 2022 were obtained from data storage units of devices. We selected two groups blood: first group with thrombocytopenia (n = 49) second that gave an aggregation and/or clumping flag 32). The results 190 consecutive patients normal counts, no flag, evaluated as control group. Pearson’s correlation coefficients, Bland-Altman plots, paired t-tests calculated. Results: plot difference PLT-I PLT-O showed mean –43.6 (95%: –17.2 –69.9); when we compared PLT-E, bias improved –6.1 –18.26 6.1) in samples flags (Bland-Altman plots). In without clumping, plot, differences means all close zero, there definite biases. Conclusions: Examining system show clumps has potential improve day-to-day laboratory routine.
