Learner Task
Required Evidence:
Practical report or observation record detailing the application of basic laboratory techniques (e.g., pipetting, centrifuging, slide preparation); and a technical guide on the selection of appropriate laboratory tools for specific diagnostic tasks.
Objective:
Demonstrate technical proficiency in fundamental laboratory procedures. You must show that you can select the correct tools and apply standardized techniques to ensure sample integrity, precision, and safety in a clinical environment.
Instructions:
Technical Guide to Laboratory Tools:
- For five specific tasks (e.g., Measuring 10μL of serum, Separating plasma from cells, Sterilizing loops), identify the correct tool and provide a technical justification for its selection over alternatives.
- Explain the safety considerations for each tool, referencing COSHH and Personal Protective Equipment (PPE) requirements.
Laboratory Techniques Practical Report:
- Document the step-by-step procedure for three core laboratory techniques:
- Aseptic Technique: Describe the process of working within a sterile field to prevent contamination.
- Centrifugation: Detail the critical steps of balancing loads and selecting the correct Relative Centrifugal Force (RCF).
- Pipetting: Outline the “forward” and “reverse” pipetting methods and how to avoid aerosol generation.
Procedure-Specific Risk Management:
- For one of the techniques above, identify two potential “Procedural Errors” (e.g., using a damaged pipette tip or failing to lock a centrifuge lid).
- Evaluate the impact of these errors on both the Diagnostic Result and Technician Safety, referencing the Health and Safety at Work Act 1974.
Sample Integrity and Tool Choice:
- Explain how the choice of tool (e.g., a glass vs. plastic pipette) can affect “Analyte Adsorption” or sample degradation.
- Discuss the importance of using “Calibrated” tools to meet ISO 15189 requirements for measurement traceability.
Reflective Account on Technical Competence:
- Write a 500-word reflection on how mastering these basic “manual” techniques is essential even in a highly automated laboratory.
- Discuss how “Manual Dexterity” and “Attention to Detail” during tool selection contribute to the overall quality of the diagnostic pathway.
