Performance of digital morphology analyzer Medica EasyCell assistant

Area of Science:

• Hematology
• Medical Technology
• Digital Pathology

Background:

• Digital morphology analyzers offer advanced solutions for hematological analysis.
• Automated systems aim to improve efficiency and accuracy in clinical laboratories.

Purpose of the Study:

• To evaluate the performance of the EasyCell assistant for white blood cell (WBC) differentials and platelet (PLT) count.
• To compare the EasyCell assistant's results with manual microscopic review and the Pentra DX Nexus analyzer.

Main Methods:

• 225 samples (100 normal, 125 abnormal) were analyzed for WBC differentials and PLT counts.
• EasyCell assistant results were compared against manual counting (Clinical and Laboratory Standards Institute guidelines) and Pentra DX Nexus.
• Correlation coefficients (r) were calculated for neutrophils, lymphocytes, and eosinophils pre- and post-user verification.

Main Results:

• Pre-verification, moderate correlations were observed for WBC differentials (neutrophils r=0.58, lymphocytes r=0.69, eosinophils r=0.51).
• Post-verification, high correlations were achieved (neutrophils r=0.74, lymphocytes r=0.78, eosinophils r=0.88, other cells r=0.91).
• Platelet (PLT) counts showed a high correlation with Pentra DX Nexus (r=0.82).

Conclusions:

• EasyCell assistant demonstrates acceptable performance for WBC differentials and PLT counts, even in abnormal samples.
• User verification significantly enhances the accuracy of WBC differential analysis.
• The EasyCell assistant has the potential to optimize hematology laboratory workflows by reducing manual review workload.
