SUMMARY

We used a total number of 702 blood samples to evaluate the automated analyser’s differential of the SE-9500 with the results of the microscopic examination of peripheral blood smears. These results were than compared to results obtained after an adjustment of the Qflag trigger levels. This significantly reduced the number of false positive samples by 37% and the microscopic workload by 14%. At the same time the specificity of flags was also improved.
