• How will you prepare for potential challenges, such as differentiating between co-migrating variants or handling results that fall outside of quality control limits?
• How do you feel about embarking on this training activity, and how might these feelings influence your focus during the preparation phase?

In action

What are you doing?

• As you begin the analysis of the HPLC plot or gel electrophoresis bands, what specific features are you focusing on first, and why have you prioritised them?
• What decisions are you making regarding the identification of specific peaks or bands, and how are you determining their clinical significance for the case?
• Which aspects of interpreting these electrophoretic patterns feel intuitive to you, and which parts—such as identifying rare variants or quantifying minor fractions—require more conscious effort?
• How are you approaching the selection of these specific techniques for the clinical presentation you are investigating?

How are you progressing with the activity?

• How effective is your current analytical approach in allowing you to interpret results for red cell, white cell, or haemostatic disorders?
• What challenges or ambiguities are you facing as the interpretation unfolds (e.g., overlapping peaks on HPLC or faint bands on a gel)?
• How does the data you are currently interpreting connect to your existing knowledge of haematological malignancies and transfusion serology?
• In what ways are you applying the principles of internal quality control (IQC) and external quality assessment (EQA) to verify that the assay performance is robust before you finalise your conclusions?
• What are you learning about the practical limitations of HPLC and gel electrophoresis as you engage with these specific results?

How are you adapting to the situation?

• Are there alternative diagnostic techniques you should consider selecting to follow up on the findings you are currently interpreting?
• How are you adapting your communication style in the moment to ensure your interpretation will be clear and actionable for a healthcare professional colleague?
• What support or reference material (such as a library of variants or SOPs) do you find yourself needing to consult to resolve uncertainties in the data?
• Are you confident that your interpretation remains within your current scope of practice and the established laboratory guidelines?

On action

What did you notice?

• What were the key steps you took to analyse the visual data from both HPLC chromatograms and gel electrophoresis bands?
• What specific parameters or diagnostic markers did you notice and focus on while interpreting results for cases such as red cell disorders or haematological malignancies?
• How did you evaluate the internal quality control (IQC) and external quality assessment (EQA) data to conclude whether the assay performance was acceptable before interpreting the patient results?
• What did you notice about the way you communicated your findings to colleagues? Were you able to present the complex data clearly and effectively?
• Were there any unexpected challenges during the interpretation process, such as ambiguous banding or overlapping peaks, and how did you identify them?
