Technical Haematology Interview Questions

Advanced Morphology and Blood Disorders

Complex Case Scenarios: ``` Question: "A 45-year-old patient presents with fatigue and pallor. The FBC shows: Hb 6.5 g/dL, MCV 65 fL, RBC count 6.2 × 10¹²/L. Blood film shows microcytic, hypochromic red cells with target cells and occasional nucleated RBCs. What are your differential diagnoses and what additional tests would you recommend?"

Expert Answer Framework: Clinical Assessment: "This presentation suggests a microcytic anemia with target cells, indicating possible thalassemia or hemoglobinopathy. The elevated RBC count despite low hemoglobin is particularly suggestive of beta-thalassemia trait or minor."

Differential Diagnoses: 1. Beta-thalassemia trait/minor 2. Alpha-thalassemia (HbH disease) 3. Iron deficiency anemia (less likely with target cells) 4. Hemoglobin E trait 5. Unstable hemoglobin variant

Recommended Testing: "I would recommend hemoglobin electrophoresis or HPLC, HbA2 and HbF quantification, iron studies to exclude deficiency, and possibly DNA analysis for alpha-globin deletions if indicated." ```

Malignant Haematology Questions: ``` Question: "Describe the morphological and immunophenotypic features that would help you distinguish between acute lymphoblastic leukemia (ALL) and acute myeloid leukemia (AML) in an adult patient."

Comprehensive Response: Morphological Differences: ALL: Small to medium blasts, high nuclear-cytoplasmic ratio, fine chromatin, indistinct nucleoli, scanty cytoplasm AML: Larger blasts, prominent nucleoli, more cytoplasm, possible Auer rods, cytoplasmic granules

Immunophenotyping: ALL: CD19, CD10, CD22 (B-cell); CD2, CD7, CD3 (T-cell) AML: CD13, CD33, MPO, CD117, specific lineage markers

Additional Testing: "Flow cytometry is essential for definitive classification. Cytogenetics and molecular studies provide prognostic information and guide treatment decisions. PAS stain may show block positivity in ALL, while myeloperoxidase is positive in AML." ```

Coagulation and Hemostasis

Complex Coagulation Scenarios: ``` Question: "A patient has prolonged APTT but normal PT. Mixing studies show partial correction. Factor VIII level is 15%. What is your interpretation and what additional tests would you perform?"

Expert Analysis: Initial Interpretation: "This pattern suggests factor VIII deficiency, but the partial correction in mixing studies indicates possible inhibitor presence. The 15% factor VIII level could indicate mild hemophilia A or acquired factor VIII inhibitor."

Additional Testing Strategy: 1. Bethesda assay to quantify inhibitor levels 2. Factor VIII inhibitor screening at multiple time points 3. Incubated mixing study (2-hour incubation) 4. von Willebrand factor studies (VWF:Ag, VWF:RCo, VWF:CB) 5. Family history and clinical correlation

Clinical Significance: "If inhibitor positive, this could indicate acquired hemophilia A, requiring different treatment approach than congenital hemophilia. Von Willebrand disease type 2N should also be considered." ```

Thrombosis Investigation Questions: ``` Question: "Outline your approach to thrombophilia screening for a 28-year-old woman with recurrent DVT and family history of thrombosis."

Systematic Approach: Screening Strategy: "Thrombophilia screening should be performed at least 3 months after acute event and off anticoagulation if safely possible."

First-Line Tests:

Additional Considerations: "Given family history, I would also consider Factor VIII levels, homocysteine, and possibly more extensive genetic testing. Clinical factors like oral contraceptive use, pregnancy history, and other risk factors should be documented." ```

Blood Transfusion Science Questions

Complex Compatibility Testing

Antibody Investigation Scenarios: ``` Question: "A patient requires urgent blood transfusion. Initial antibody screen is positive with all three cells. Direct antiglobulin test is positive. How would you proceed with compatibility testing?"

Emergency Protocol Response: Immediate Actions: "This suggests multiple antibodies or warm autoantibodies. I would immediately inform the clinical team of the complexity and potential delay while ensuring patient safety."

Investigation Strategy: 1. Extended phenotyping of patient sample 2. Autocontrol and direct antiglobulin test investigation 3. Antibody identification panel with enhancement techniques 4. Warm and cold testing protocols 5. Adsorption studies if autoantibodies suspected

Compatible Blood Strategy: "If urgent transfusion required, I would provide least incompatible blood after consultant hematologist discussion, with enhanced monitoring protocols and proper documentation of risks." ```

Hemolytic Disease Investigation: ``` Question: "A newborn shows signs of hemolysis. Maternal antibody screen shows anti-c. Cord blood DAT is positive. Describe your investigation approach."

Comprehensive Investigation: Maternal Studies:

Neonatal Assessment: Treatment Coordination: "Close communication with neonatology team regarding phototherapy, exchange transfusion criteria, and compatible blood provision. Monitor for late-onset anemia requiring top-up transfusions." ```

Leadership and Management Questions

Team Leadership Scenarios

Staff Management Questions: ``` Question: "A junior member of your team consistently makes errors in blood film reporting. How would you address this situation?"

Leadership Response Framework: Assessment Phase: "I would first analyze the types of errors to identify patterns - are they knowledge gaps, procedural issues, or attention problems? Review recent training records and competency assessments."

Intervention Strategy: 1. Private discussion to understand underlying issues 2. Targeted training plan development 3. Increased supervision and double-checking procedures 4. Regular feedback sessions and progress monitoring 5. Documentation of interventions and outcomes

Support Approach: "Focus on supportive development rather than punitive measures. Identify root causes - workload, training gaps, personal issues - and provide appropriate support while maintaining patient safety." ```

Quality Management Scenarios: ``` Question: "Your laboratory fails a proficiency test for factor VIII assay. How would you investigate and respond?"

Quality Management Response: Immediate Actions: "Stop patient testing for factor VIII until investigation complete. Review recent patient results for potential clinical impact. Inform laboratory manager and consultant hematologist immediately."

Investigation Process: 1. Review assay performance data and quality control trends 2. Check calibration, reagent lots, and equipment function 3. Repeat analysis with fresh calibrators and controls 4. Compare results with reference method if available 5. Review staff competency and recent procedural changes

Corrective Actions: "Implement corrective measures, validate effectiveness, and resume testing only when confident in assay performance. Submit corrective action report to proficiency testing provider with evidence." ```

Service Development Questions

Innovation and Improvement: ``` Question: "Describe how you would implement a new molecular diagnostic test for BCR-ABL monitoring in your laboratory."

Implementation Strategy: Planning Phase:

Validation Process: Implementation: ```

Behavioral and Situational Questions
