Assessment Criteria
Key criteria assessors look for in your portfolio
- Award credit for demonstrating correct calibration, cleaning, and routine maintenance of laboratory equipment such as microscopes, centrifuges, and haematology analysers according to manufacturer guidelines.
- Assess candidate's ability to collect a blood sample into the appropriate anticoagulant tube, label it with full patient details and date, and transport it safely to the laboratory without haemolysis or contamination.
- Evidence of selecting and wearing personal protective equipment (PPE) including lead gowns and dosimeters, and applying the ALARA principle to minimise radiation exposure during positioning for radiographs.
- Expect the candidate to perform and interpret a basic diagnostic test (e.g., packed cell volume, urine specific gravity) with acceptable accuracy and repeatability, recording results clearly in patient records.
Assessment Guidance
Guidance for achieving higher grades
- 💡In practical assessments, verbally narrate your actions to demonstrate awareness of aseptic technique, patient stress reduction, and safety checks, even if not explicitly asked.
- 💡For written tasks on X-ray safety, reference specific legislation such as the Ionising Radiation Regulations (IRR) and Ionising Radiation (Medical Exposure) Regulations (IR(ME)R) to show regulatory knowledge.
- 💡Prepare a portfolio of evidence that includes photographic records of equipment maintenance logs, sample handling protocols, and signed witness statements from supervisors.
- 💡During OSCEs, double-check sample labels aloud and confirm patient identity against the clinical notes before proceeding with any diagnostic test.
- 💡Revise the normal reference ranges for common haematological and biochemical parameters so you can immediately flag abnormal results during analysis.
- 💡Use correct terminology (e.g., 'pyrexia' for fever, 'tachycardia' for fast heart rate) to demonstrate knowledge.
- 💡Always link practical procedures to underlying principles (e.g., why aseptic technique is important).
- 💡Read questions carefully: if asked to 'describe', give a step-by-step account; if 'explain', include reasons.
Common Mistakes
Common errors to avoid in your coursework
- Confusing sample tube additives: using EDTA for biochemistry tests that require serum, or using plain tubes for haematology, leading to invalid results.
- Failing to calibrate or zero a refractometer between readings, causing cumulative errors in urine specific gravity or plasma protein measurements.
- Inadequate manual restraint during ultrasound, resulting in excessive movement, poor image quality, or risk of injury to animal and personnel.
- Overlooking the need to shield the primary beam and collimate to the area of interest during radiography, exposing adjacent body parts unnecessarily.
- Disposing of clinical waste (e.g., used needles, blood-stained swabs) in general waste bins instead of designated sharps or clinical waste containers.
- Misconception: 'A dog's normal temperature is 38.5°C.' Correction: Normal range is 37.8–39.2°C; 38.5°C is within range but not a fixed value.
- Misconception: 'Disinfectant kills all germs immediately.' Correction: Disinfectants require appropriate contact time and must be used on clean surfaces to be effective.
- Misconception: 'Scruffing a cat is always safe.' Correction: Scruffing can cause stress and is only appropriate for short periods; modern handling uses minimal restraint.
Revision Plan
How to revise this topic in 1–2 weeks
- 1Week 1: Focus on animal handling and restraint. Practice with videos or role-play. Learn normal vital signs.
- 2Week 2: Study infection control and hygiene protocols. Create flashcards for disinfectant types and uses.
- 3Week 3: Review nutrition and feeding. Compare dietary needs of dogs, cats, and rabbits.
- 4Week 4: Consolidate with past exam questions. Focus on command words like 'describe' and 'explain'.
Exam Question Types
How this topic typically appears in the exam
- 📋Short-answer questions: e.g., 'List three signs of pain in a cat.' Advice: Use specific behaviours (e.g., hiding, reduced appetite).

Step-by-Step Worked Solutions
Detailed solution breakdown for typical exam problems
Question: A veterinary practice needs to calculate the daily fluid requirement for a 12 kg dog. The standard rate is 50 ml/kg/day. Calculate the total volume required per day and state how this should be administered.
- 1.Step 1: Identify the dog's weight: 12 kg.
- 2.Step 2: Apply the formula: 50 ml/kg/day × 12 kg = 600 ml/day.
- 3.Step 3: State administration: Fluids should be given orally or via subcutaneous or intravenous route as prescribed by the vet, in divided doses (e.g., 200 ml three times daily).
Question: Describe the correct procedure for cleaning a kennel after a dog has been discharged, including infection control measures.
- 1.Step 1: Remove all bedding, bowls, and toys; dispose of waste in clinical waste bin.
- 2.Step 2: Clean surfaces with a detergent solution to remove organic matter.
- 3.Step 3: Apply a suitable disinfectant (e.g., a quaternary ammonium compound) and allow appropriate contact time.
- 4.Step 4: Rinse with clean water and dry thoroughly.
- 5.Step 5: Replace with fresh bedding and clean bowls before next occupant.
