The diagnostic use of ADVIA 2120i Siemens and an "APL criteria" can help to reduce the rate of early death in the APL.

The algorithm provided a high sensitivity (86.30%) and high specificity (99.83%) in APL with high or normal number of WBC and satisfactory results in APL with cytopenia (80%). The specificity was very high also in groups of hematological and nonhematological diseases. It can be used as an "APL criteria" to alert pathologists of the possible presence of APL. It together with instrumental and classical morphology may allow to reduce the time of diagnosis with further reduction in early death.
