Veterinary Clinical Pathology Course

Lesson 1 • Laboratory Safety and Quality Assurance

Covers biosafety levels, personal protective equipment, and waste disposal relevant to veterinary labs. Connects safe practice to reliable, reproducible results.

Lesson 2 • Sample Collection and Handling

Teaches proper venipuncture sites, anticoagulant selection, and pre-analytical error prevention. Correct handling directly affects result accuracy.

Lesson 3 • Reference Intervals and Result Interpretation

Explains how reference intervals are established and how to apply them to patient data. Students learn to distinguish normal biological variation from pathological change.

Lesson 4 • Role of Clinical Pathology in Practice

Defines clinical pathology's diagnostic function and its integration with physical examination. Establishes why laboratory data guides clinical decision-making.

Lesson 1 • Complete Blood Count Parameters

Covers RBC count, haemoglobin, haematocrit, and erythrocyte indices. These parameters form the quantitative basis for all red cell assessments.

Lesson 2 • Blood Smear Preparation and Staining

Teaches wedge smear technique, Romanowsky staining, and smear quality assessment. A well-prepared smear is essential for accurate morphological evaluation.

Lesson 3 • Erythrocyte Morphology and Abnormalities

Identifies normal and abnormal RBC shapes, inclusions, and colour changes. Morphological findings direct the differential diagnosis of anaemia.

Lesson 4 • Polycythaemia and Erythrocytosis

Distinguishes relative, absolute primary, and secondary erythrocytosis using clinical and laboratory criteria. Connects elevated RBC mass to underlying pathophysiology.

Lesson 1 • Leukocyte Differential and Normal Morphology

Covers identification and counting of neutrophils, lymphocytes, monocytes, eosinophils, and basophils. Accurate differentials are the foundation of leukogram interpretation.

Lesson 2 • Inflammatory Leukogram Patterns

Teaches interpretation of neutrophilia, left shift, toxic change, and lymphopenia in the context of inflammation. Patterns guide assessment of infection severity.

Lesson 3 • Lymphocytosis and Immune Responses

Distinguishes reactive lymphocytosis from neoplastic lymphocyte proliferation using morphological criteria. Connects immune activation to leukogram changes.

Lesson 4 • Leukaemia and Myeloproliferative Disorders

Introduces acute and chronic leukaemia classification and bone marrow involvement. Students apply morphological and quantitative criteria to suspect neoplastic disease.

Lesson 1 • Electrolytes and Acid-Base Assessment

Covers sodium, potassium, chloride, bicarbonate, and anion gap in metabolic and respiratory disorders. Electrolyte patterns guide fluid therapy and diagnosis.

Lesson 2 • Pancreatic and Gastrointestinal Markers

Covers lipase, amylase, TLI, and cobalamin as indicators of exocrine pancreatic and intestinal disease. Marker selection depends on species and clinical presentation.

Lesson 3 • Hepatic Enzyme and Function Tests

Covers ALT, AST, ALP, GGT, bilirubin, and bile acids as markers of hepatocellular injury and cholestasis. Enzyme patterns distinguish hepatic from extrahepatic disease.

Lesson 4 • Renal Function and Urinary Markers

Teaches BUN, creatinine, SDMA, and phosphorus as indicators of glomerular filtration. Early renal biomarkers enable detection before overt azotaemia develops.

Lesson 1 • Urine Collection and Physical Properties

Covers cystocentesis, catheterisation, and free-catch collection methods and their effect on results. Physical properties provide the first tier of urinalysis data.

Lesson 2 • Urine Chemistry Dipstick Analysis

Teaches dipstick interpretation for protein, glucose, ketones, bilirubin, blood, and pH. Species-specific dipstick limitations prevent misinterpretation.

Lesson 3 • Urine Sediment Microscopy

Identifies casts, cells, crystals, bacteria, and fungi in centrifuged urine sediment. Sediment findings localise disease to the kidney or lower urinary tract.

Lesson 4 • Renal and Bladder Cytology

Covers cytological evaluation of renal aspirates and bladder wash samples for neoplasia and infection. Cytology complements urinalysis in complex urinary cases.

Lesson 1 • Cytological Criteria of Malignancy

Teaches nuclear and cytoplasmic features that indicate malignant transformation. Recognising malignancy criteria is central to cytological diagnosis.

Lesson 2 • Epithelial and Mesenchymal Tumour Cytology

Covers cytological features of carcinomas, adenocarcinomas, and sarcomas. Cell arrangement and cohesion patterns differentiate tumour lineage.

Lesson 3 • Cytology Sample Collection Techniques

Covers fine-needle aspiration, impression smears, and swab techniques for various tissue types. Technique selection determines cellularity and diagnostic quality.

Lesson 4 • Inflammatory and Reactive Lesion Cytology

Distinguishes suppurative, granulomatous, and mixed inflammation from reactive hyperplasia. Inflammatory patterns guide microbiological follow-up.

Lesson 1 • Coagulation Testing and Interpretation

Covers PT, aPTT, fibrinogen, D-dimer, and antithrombin as diagnostic tools. Test selection and interpretation depend on the suspected pathway affected.

Lesson 2 • Inherited and Acquired Coagulopathies

Covers factor deficiencies, von Willebrand disease, and rodenticide toxicosis as causes of secondary haemostasis failure. Species predispositions guide diagnostic prioritisation.

Lesson 3 • Physiology of Haemostasis

Reviews vascular response, platelet plug formation, and coagulation cascade in sequence. Physiological understanding is prerequisite to interpreting coagulation test abnormalities.

Lesson 4 • Thrombocytopenia and Platelet Disorders

Differentiates immune-mediated, consumptive, and production-failure thrombocytopenia using laboratory criteria. Platelet function disorders are distinguished from quantitative deficits.

Lesson 1 • Systematic Approach to Case Interpretation

Establishes a stepwise framework for integrating CBC, chemistry, urinalysis, and cytology data. A consistent approach reduces diagnostic error and omission.

Lesson 2 • Multi-System Disease Case Studies

Applies integrated interpretation to cases involving concurrent hepatic, renal, and haematological abnormalities. Complex cases reinforce cross-system pattern recognition.

Lesson 3 • Quality Improvement and Diagnostic Error

Covers root cause analysis of diagnostic errors and laboratory quality improvement cycles. Systematic error review builds long-term diagnostic accuracy.

Lesson 4 • Species-Specific Diagnostic Considerations

Highlights key laboratory differences among dogs, cats, horses, ruminants, and exotic species. Species context prevents misclassification of normal variation as pathology.
