The Art And Science Of Haematology Morphology


The enumeration and analysis of blood cells with automated haematology analysers have significantly improved in recent years due to advances in cell detection technologies, which have reduced the manual differential rate. Despite these improvements, morphology remains a keystone of haematology. A thorough understanding of the principles and mechanisms behind Romanowsky staining methods can enhance laboratory practice in areas such as implementing new instruments or procedures, and troubleshooting poor staining performance. These ideas and suggestions are exemplified by a selection of patient cases showing how analytical results are complemented by good quality blood films and staining.

Alinity hq Sigma Metrics

Sten Westgard explains how sigma metrics are derived from the TEa target and the actual imprecision and bias of a particular assay/device. Discussion will include real life results obtained by various hematology analyzers as well as the impact on a laboratory’s quality control strategy of measuring the analytical performance using the Six Sigma scale.

Advanced Optical Hematology Technology for Elevated Analytical Performance

Review principles and capabilities of Abbott’s Advanced Multi-Angle Polarized Scatter Separation technology and patient cases obtained on the hematology system.

Advancements in WBC Differential Technology

Don Wright discusses the general principles of automated WBC and differential technology, processing limitations associated with available options, and discuss key technology trends.
