Clinical Hematology
Interpret complete blood counts, peripheral blood smears, and coagulation profiles as diagnostic windows into bone marrow and systemic disease processes.
A focused guide for planning your study. Follow the current syllabus and teaching guidance from your own institution when deciding what to cover.

A working method
Recommended Focus
Anemia Workup & RBC Indices: 40% | Smear Morphology & Leukemias: 35% | Hemostasis & Transfusion: 25%
Approach hematology cases by analyzing red cell indices (MCV, MCH, MCHC, RDW) alongside reticulocyte counts before ordering invasive testing. Interpret peripheral blood films systematically: evaluate RBC morphology, WBC differential and maturity, and platelet estimation. For bleeding disorders, integrate PT, aPTT, and platelet counts to localize defects in primary versus secondary hemostasis.
Ask Yourself
Do the RBC indices and reticulocyte response indicate impaired marrow production, accelerated destruction, or acute blood loss?
Actionable Study Checklist
- 1Practice calculating and interpreting red cell indices and discriminant formulas
- 2Identify characteristic cells on blood smears: sickle cells, target cells, spherocytes, blast cells
- 3Draw the coagulation cascade linking intrinsic/extrinsic pathways to aPTT and PT tests
- 4Review blood grouping, crossmatching, and acute hemolytic transfusion reaction algorithms
Common Pitfalls & Examiner Red Flags
- !Interpreting serum ferritin in isolation without accounting for acute-phase reactant elevations
- !Failing to examine reticulocyte count when evaluating severe anemia
- !Confusing findings of immune thrombocytopenia (ITP) with thrombotic microangiopathies (TTP/HUS)
