The Role of Automated Hematology Analyzers in Improving Diagnostic Accuracy: A Full Research Study

Abstract

Automated hematology analyzers (AHAs) are essential tools in modern clinical laboratories, providing rapid, precise, and reproducible complete blood count (CBC) analysis. This study evaluated the impact of AHAs on diagnostic accuracy compared to conventional manual methods. A cross-sectional study was conducted on 300 blood samples collected from patients with various hematological conditions. Samples were analyzed using automated analyzers and manual microscopy as a reference. Results demonstrated strong correlation for RBC, WBC, and platelet counts (r > 0.95, p < 0.001). Automated flagging systems identified abnormal cells with >92% sensitivity. These findings confirm that AHAs enhance diagnostic reliability, reduce human error, and improve laboratory workflow, while manual review remains essential for rare abnormalities.
