FDA Study Data Validation Rules
FDA’s June 2026 conformance guide describes several layers of study-data validation, including standards conformance checks, FDA business rules, validator rules, and technical rejection criteria used at different stages. These requirements are current FDA technical-conformance guidance for electronic study-data submissions and should be rechecked when FDA guidance, supported standards, or eCTD specifications change.
Evaluate submitted study data against the applicable current conformance, business, validator, and rejection checks before submission and address meaningful discrepancies.
