GxP
Good "x" Practice
What a definition is not
A definition is SPEQ’s plain-language decode of how a term is used in practice, cited to the documents that define it. It is a practitioner reference, not legal or regulatory advice, it does not replace the definition in the source, and where a regulator’s wording differs the regulator’s wording governs.
GxP is the collective abbreviation for the family of "good practice" quality guidelines and regulations across the regulated lifecycle — the "x" standing in for the discipline, as in GMP (manufacturing), GCP (clinical), GLP (non-clinical laboratory), GDP (distribution), and GVP (pharmacovigilance). Though each discipline has its own detailed rules, all GxP frameworks share a common intent: ensure that products are safe and effective and that the data supporting them are trustworthy, attributable, and reconstructable. The umbrella term captures that shared philosophy of documented, controlled, evidence-based work.
The unifying threads across every GxP are traceability, documentation, control, and data integrity — do what your procedures say, record it contemporaneously, and be able to prove it afterward. A practitioner who understands those threads can move between disciplines even though the specific regulations differ.
The list is open-ended by construction: newer entrants such as good automated manufacturing practice and good machine learning practice extend the "x" as new activities become subject to the same quality logic.
