Blood Count Interpretation Course

Lesson 1 • Blood Composition and Functions

Covers plasma, cellular components, and their systemic roles. Provides the anatomical baseline needed for all subsequent CBC interpretation.

Lesson 2 • Bone Marrow and Peripheral Blood

Distinguishes marrow production from peripheral circulation findings. Grounds students in why CBC values reflect marrow output.

Lesson 3 • Homeostatic Regulation of Blood Counts

Explains feedback loops controlling cell production and destruction. Students understand why counts fluctuate within reference ranges.

Lesson 1 • Platelet Parameters and Indices

Explains platelet count, MPV, and PDW. Links platelet indices to production kinetics and clinical relevance.

Lesson 2 • CBC Report Structure and Layout

Introduces the standard CBC format and parameter groupings. Orients students to navigate any laboratory report confidently.

Lesson 3 • White Cell Parameters and Differential

Covers total WBC count and the five-part differential. Students learn how automated and manual differentials are generated.

Lesson 4 • Red Cell Parameters Explained

Defines RBC count, haemoglobin, haematocrit, and red cell indices. Connects each index to specific aspects of red cell size and haemoglobin content.

Lesson 1 • Communicating CBC Findings Clearly

Covers structured reporting of CBC interpretations to clinical teams. Students practise concise, actionable language for written and verbal communication.

Lesson 2 • Identifying Abnormal Values

Teaches recognition of high, low, and borderline results. Students distinguish true abnormalities from analytical artefacts.

Lesson 3 • Establishing a Reading Framework

Introduces a sequential review order for CBC parameters. Prevents random scanning and ensures no parameter is overlooked.

Lesson 4 • Correlating CBC Parameters Together

Demonstrates how parameters interact to narrow differential diagnoses. Students practise multi-parameter pattern recognition.

Lesson 1 • Haemolytic Anaemia Differentiation

Focuses on CBC and peripheral smear clues distinguishing intrinsic from extrinsic haemolysis. Students identify schistocytes, spherocytes, and related findings.

Lesson 2 • Microcytic Anaemias

Covers iron deficiency, thalassaemia, and sideroblastic anaemia. Students use MCV, RDW, and iron studies to differentiate causes.

Lesson 3 • Normocytic Anaemias

Addresses the broad normocytic category including haemolysis, aplasia, and mixed deficiencies. Reticulocyte count is the key discriminator.

Lesson 4 • Macrocytic Anaemias

Distinguishes megaloblastic from non-megaloblastic macrocytosis. Students identify B12, folate deficiency, and drug-induced causes.

Lesson 1 • Interpreting the Differential in Context

Integrates differential findings with total WBC and clinical scenario. Students practise generating ranked differentials from CBC data alone.

Lesson 2 • Leukocytosis: Causes and Patterns

Covers neutrophilia, lymphocytosis, eosinophilia, and monocytosis. Students use absolute counts and clinical context to identify likely causes.

Lesson 3 • Leukopenia and neutropenia

Defines absolute neutrophil count thresholds and infection risk. Students recognise drug-induced, autoimmune, and marrow failure causes.

Lesson 4 • Reactive versus malignant white cell changes

Teaches CBC clues that distinguish infection-driven leukocytosis from leukaemia. Students identify blast presence, pancytopenia, and leukoerythroblastic patterns.

Lesson 1 • Thrombocytosis and reactive elevation

Distinguishes reactive thrombocytosis from essential thrombocythemia. Students use clinical context and CBC patterns to differentiate causes.

Lesson 2 • Immune and drug-induced thrombocytopenia

Covers ITP, heparin-induced thrombocytopenia, and drug-related causes. Students recognise CBC patterns and timing clues for each condition.

Lesson 3 • MPV and platelet morphology clues

Uses MPV and PDW to infer platelet production kinetics. Students apply platelet indices to narrow thrombocytopenia differential.

Lesson 4 • Thrombocytopenia: causes and severity

Classifies thrombocytopenia by mechanism and severity threshold. Students link platelet count levels to bleeding risk categories.

Lesson 1 • CBC in renal and hepatic disease

Identifies anaemia of chronic kidney disease and liver-related CBC changes. Students link organ dysfunction to specific CBC parameter shifts.

Lesson 2 • CBC in nutritional deficiencies

Links iron, B12, folate, and copper deficiency to specific CBC patterns. Students use indices to identify and prioritise nutritional causes.

Lesson 3 • CBC in inflammatory and infectious states

Covers CBC changes in bacterial, viral, and fungal infections. Students distinguish acute from chronic inflammatory CBC patterns.

Lesson 4 • CBC in autoimmune and rheumatic diseases

Covers CBC findings in lupus, rheumatoid arthritis, and vasculitis. Students recognise autoimmune cytopenias and their CBC signatures.

Lesson 1 • Quality assurance and interpretive limits

Addresses the boundaries of CBC interpretation and when additional testing is mandatory. Students recognise their interpretive scope and escalation responsibilities.

Lesson 2 • Myeloproliferative neoplasm CBC patterns

Identifies CBC signatures of polycythaemia vera, CML, and myelofibrosis. Students recognise hallmark findings that prompt specialist referral.

Lesson 3 • Acute leukaemia recognition on CBC

Covers CBC red flags for acute myeloid and lymphoid leukaemia. Students identify blast flags, cytopenias, and urgent referral criteria.

Lesson 4 • Complex multi-lineage case analysis

Presents cases with overlapping abnormalities across all three cell lines. Students practise systematic reasoning to reach a single best interpretation.
