Decoding the CBC: A Pattern Atlas of Complete Blood Count

The modern haematology analyser sees more than it reports. This atlas teaches you to read what it sees. The five-part differential analyser produces far more than a printed count. Its scattergrams, histograms, and research parameters carry patterns: the early flag of a circulating blast, the signature of a reactive lymphocyte, the histogram shape that separates iron deficiency from thalassaemia trait. Organised by cell line, each chapter pairs real analyser output with the peripheral smear and, where it decides management, the confirmatory flow cytometry. One reasoning thread runs from the scattergram and the reflex-to-smear decision to a validated, decision-ready CBC report. Inside this atlas: RBC, WBC, and platelet histogram and scattergram pattern atlases; the WDF, WPC, and PLT-F channels; neutrophil reactivity, immature granulocyte, and HFLC parameters; the analyser-smear-flow triad for lymphoid and myeloid neoplasms; reflex algorithms, quality control, and reference-interval logic; and integrated cases that close on a validated report and its next step.
