The 2014 evidence-based guideline, "Principles of Analytic Validation of Immunohistochemical Assays," serves as a practical guide to help ensure accuracy and reduce variation in laboratory practices for immunohistochemical (IHC) test results for all patient specimens. <> This recommendation does not apply to any marker for which a separate validation guideline already exists. Adopting these guidelines helps pathologists and laboratory professionals to provide more effective testing with consistent, high-quality results, and expert interpretations. Printable versions of the standards (in Word or PDF formats) are available for free.
