Learn key differences between Validation protocol and report with frequently asked questions (FAQs) to help you better understand and implement them.
Validation Protocol and Report play a vital role in Analytical method validation. A Validation Protocol is a forward-looking, pre-approved plan detailing how an analytical method will be evaluated, while a Validation Report is a retrospective document that summarises the study results and determines if the method meets the predefined acceptance criteria.
Analytical method validation ensures that a specific test method reliably and accurately measures what it is intended to. Two critical documents guide this process: the Analytical Method Validation Protocol and the Analytical Method Validation Report. While both are interrelated, they serve distinct purposes.
In this blog, I will discuss the key differences between these two documents and address frequently asked questions (FAQs) to help you better understand and implement them.
A Validation Protocol is a pre-defined plan that outlines how a method will be validated. It is a forward-looking document and must be approved before the validation study begins.
A Validation Report is a retrospective document that summarises the results of the validation study. It compares the actual data with the pre-defined criteria from the protocol and concludes whether the method is valid.

Understanding the distinction between analytical method validation protocols and reports is essential for regulatory compliance, audit readiness, and ensuring your analytical methods are scientifically sound.
A well-designed protocol lays the groundwork for success, while a comprehensive report validates and documents it.

No
No. Any additional work or deviation will be included in the report with sceintific justification
Protocol: Usually written by analytical scientists or QA professionals before validation.
Report: Typically compiled by the same team after experiments are complete, often with QA review.
Yes, both are essential for audits, inspections, and regulatory filings. Agencies expect a clear link between planned validation (protocol) and executed validation (report).
