Contract Testing Laboratories
Contract analytical, microbiological, and stability laboratories — running compendial and validated methods, and defending data integrity for their clients.
Contract testing laboratories run analytical, microbiological, stability, and bioanalytical testing for sponsors, manufacturers, and CROs. They release raw materials and finished product, support stability programs, and generate the compendial data on which a batch disposition or a submission depends. The lab’s result is often the last check before product reaches a patient.
GMP testing labs work to 21 CFR 211 subpart I (laboratory controls) and the USP compendia; GLP-regulated studies to 21 CFR Part 58 and OECD GLP; and many labs additionally carry ISO/IEC 17025 accreditation. Method validation and transfer follow ICH Q2 and USP general chapters, and every result lives under 21 CFR Part 11 data-integrity expectations.
The customer qualifies and audits the lab and remains responsible for the decision made on the lab’s data; the lab is responsible for method suitability, competent execution, and the integrity of the result. A quality/technical agreement defines method ownership, OOS handling, and data return — and the lab must be able to reconstruct any reported result from its raw data on demand.
Method validation & transfer
Demonstrating that a method is suitable and performs the same at the contract lab as at the originator (ICH Q2, USP) before any reportable result is generated.
OOS & OOT investigations
Sound out-of-specification and out-of-trend handling — the single most inspected laboratory process, where weak investigations invalidate the result.
Data integrity & raw-data traceability
Audit trails, second-person review, and the ability to reconstruct every reported value from instrument raw data (ALCOA+).
Compendial & microbiological control
Correct application of USP methods and microbiological limits, including environmental and sterility testing where in scope.
- ›Invalidated or unreliable results from methods that were never properly transferred
- ›Out-of-specification results closed without scientifically sound investigation
- ›Audit-trail gaps that prevent reconstruction of a reported result
- ›Contamination or handling errors in the microbiology or sterility suite
