Automated equipment used in the hematological laboratory for routine hemograms offers high sensitivity and great accuracy. In order to evaluate the liberation criteria of hemograms by direct interfacing between the electronic counters and the emission of results, 247 hemogram slides were examined. Of these using the Sysmex SE 9500 and Cell Dyn 4000 automated counters, 149 slides were considered concordant with liberation criteria by direct interfacing while 98 were considered non-concordant. Of the concordant hemograms, microscopy without access to the numeric results showed alterations in only one slide, which was considered clinically irrelevant. On the other hand, of the 98 non-concordant hemograms, 32 showed alterations. The results demonstrate the satisfactory sensitivity of the automatic systems analyzed. The slides with the non-concordant hemograms were re-examined, in order to evaluate the electronic results. Thus, it was possible to analyze the causes of the non-concordance and give suggestions for possible simplifications of the system. This study shows that the results emitted by the assessed automatic counters presented a high level of correlation with the microscopy count. Therefore, it can be concluded that the results of the hemograms liberated by the devices are satisfactory and that these devices are reliable for the routine use within the hematological laboratory.
