What must happen during transference before clinical use?

• A. It must be validated
• B. It must be published
• C. It must be recalibrated
• D. It must be compared to literature

Answer: (A)

Validation is the essential step when transferring a method or device to clinical use. It shows that the approach performs as intended in the new setting, with acceptable accuracy and precision under realistic conditions. This means demonstrating consistent results across runs, days, and operators, and confirming key performance characteristics such as linearity, detection limits, and potential interferences. Only after validation can you rely on the results for patient care. Publishing the validation findings isn’t strictly required for clinical use, though it helps others assess reliability. Recalibration may be part of ongoing maintenance, but by itself it doesn’t prove that the transference retains proper performance. Comparing to existing literature isn’t a formal requirement for clinical adoption and can’t replace actual validation.
