The Inspection Technical Guides have been composed by FDA to provide their inspectors with technical information that has not been previously available on a broad scale. For medical translators and writers, these guides may serve as a source of background knowledge, descriptions of methods and equipment, and industry-standard terminology.

The complete list of Inspection Technical Guides includes 53 ITGs (as of January 2025).

The following guides apply to drugs, medical devices, or both:
