Emphasize your adherence to regulatory guidelines and quality control measures, and illustrate your problem-solving skills by mentioning any challenges you’ve encountered and how you overcame them.
Example: “First, I establish the performance characteristics of the assay, focusing on sensitivity, specificity, reproducibility, and accuracy. I start with a comprehensive literature review and engage with the assay’s developers or manufacturers to understand its theoretical framework and any existing validation data.
Next, I design a series of experiments to test the assay using well-characterized control samples, ensuring a representative range of the conditions it will encounter in routine use. I run these samples in parallel with the established gold-standard assays to compare results, meticulously documenting any discrepancies and understanding their causes.
After the initial testing phase, I analyze the data to verify that the assay meets the required performance criteria. I also perform robustness testing to assess the assay’s tolerance to slight variations in protocol or environmental conditions. Finally, I compile a detailed validation report and present it to the relevant stakeholders, including any recommendations for procedural adjustments or additional training for lab personnel. This thorough approach ensures that the new assay is both reliable and practical for routine diagnostic use.”
