Testing Oversight & Analytical Review

TESTING OVERSIGHT & ANALYTICAL REVIEW

Ensure Accurate, Defensible, Inspection-Ready Analytical Results

Independent, audit-trained review of the test data and documentation produced by your third-party contract laboratory — verified against regulatory requirements before it supports a release decision or a submission.

Analytical data is the evidence base for every release decision, every shelf-life claim, and every regulatory submission your organization makes. When that data is generated by an external laboratory — and reviewed only by the people who generated it — you are carrying risk you cannot see.

ARIREX reviews the data package the third-party laboratory issues to you — method validation records, test results, investigation reports, and supporting documentation — the way a regulator would: against the applicable requirement, on the strength of objective evidence. We do not manage or direct the laboratory's operations; we independently assess what it produces. Regulatory responsibility for outsourced testing does not transfer to the laboratory performing it — it stays with you. Our role is to make sure the data you are relying on can carry that weight.

How the Process Works

ARIREX has no direct relationship with the third-party laboratory and does not manage its day-to-day operations. Our review begins once the laboratory has completed its work and issued its data to you:

1

Samples are sent to the laboratory

Either you send samples directly to the third-party laboratory of your choice, or ARIREX arranges sample submission on your behalf — whichever is set out in our engagement agreement.

2

The laboratory performs the testing

The laboratory conducts the analysis and issues its data, certificate of analysis, method validation package, or investigation report to you.

3

You forward the data package to ARIREX

As soft copies (electronic files) or hard copies (physical documents) — whichever suits your systems and confidentiality requirements.

4

ARIREX independently reviews the data

We assess it against the applicable regulatory requirement — method validation adequacy, specification compliance, audit trail integrity, or investigation rigour, depending on scope.

5

ARIREX delivers a written report

A risk-ranked assessment with findings traceable to objective evidence and cited to the applicable regulation, guideline, or standard.

6

You use the report

To support your release decision, strengthen a CAPA response, or defend a regulatory submission.

Whichever arrangement applies, ARIREX has no ongoing operational or commercial relationship with the laboratory itself — our review is based on the data it produces, which is what keeps the assessment genuinely independent.


When Test Data Doesn't Hold Up

Laboratory controls and data integrity remain among the most frequently scrutinized areas in regulatory inspections across the pharmaceutical sector. The consequences of weak testing data are rarely confined to the laboratory:

A submission is delayed because method validation data does not support the specification that was filed.

A batch is held while an out-of-specification investigation is reopened for insufficient root cause justification.

A contract laboratory's finding becomes your finding — regulatory accountability for outsourced testing stays with the product owner.

An audit trail gap surfaces during inspection, and every result generated on that system comes into question.

A stability programme cannot defend the shelf life already printed on the label.

A supplier qualification is challenged because the laboratory that tested your incoming material was never independently assessed.

Every one of these is recoverable. All of them are cheaper to prevent than to remediate.


Our Testing Oversight Practice Areas

ARIREX's testing practice covers eight core areas supporting laboratory quality, data integrity, and third-party test coordination across the product lifecycle.

1. Third-Party Analytical Testing Data Review

Independent review of the test data, certificates of analysis, and reporting the third-party contract laboratory issues to you — confirming that methods, specifications, and results meet US FDA, Health Canada, and EU GMP expectations, based on the records and data provided.

Ideal for: manufacturers relying on external laboratories for raw material, in-process, or finished product testing.

2. Analytical Method Validation & Verification Review

Independent review of method validation and verification packages against ICH and USP requirements — covering accuracy, precision, specificity, linearity, range, robustness, and the adequacy of the underlying raw data supporting each parameter.

Ideal for: organizations introducing a new test method, transferring a method between laboratories, or defending a method challenged during inspection.

3. Raw Material & Finished Product Testing Oversight

Review of testing programmes for raw materials, in-process samples, and finished products against compendial and registered specifications, including sampling plans, retest policies, and reduced-testing justifications.

Ideal for: manufacturers establishing or auditing their incoming and release testing programmes.

4. Stability Testing Programme Review

Review of stability study design, storage conditions, pull schedules, bracketing and matrixing justification, and data trending against ICH stability guidance and Health Canada / US FDA expectations.

Ideal for: organizations establishing shelf-life claims, extending expiry, or supporting a regulatory submission.

5. Microbiological Testing Oversight

Oversight of microbiological testing programmes, including environmental monitoring, bioburden, and sterility testing, against USP General Chapters and GMP expectations — with attention to method suitability, alert and action limits, and excursion investigation.

Ideal for: manufacturers of sterile products or facilities operating active environmental monitoring programmes.

6. Data Integrity & Laboratory Data Review

Review of laboratory data governance against ALCOA+ principles and 21 CFR Part 11 — covering audit trail review practices, chromatography data system (CDS) configuration, user access and privilege control, sample sequence and reprocessing controls, and electronic record lifecycle management.

Ideal for: organizations preparing for a data integrity-focused inspection or remediating a prior finding.

7. Out-of-Specification (OOS) & Out-of-Trend (OOT) Investigation Review

Independent review of OOS and OOT investigations for scientific rigour, adequacy of root cause determination, justification of invalidated results, and compliance with US FDA and Health Canada investigation expectations.

Ideal for: organizations strengthening their laboratory investigation process or responding to a regulatory finding.

8. Laboratory Quality System Audits

Audits of laboratory quality systems against ISO/IEC 17025 and GMP laboratory control requirements — covering equipment qualification and calibration, reference standard management, personnel training and competency, document control, and change management.

Ideal for: contract laboratories and in-house QC laboratories maintaining or pursuing accreditation, or preparing for client audits.


What You Receive

Every ARIREX engagement concludes with a documented, evidence-based deliverable package:

Data Review Report

Written findings supported by objective evidence: documents reviewed, data examined, systems assessed, personnel interviewed. Every observation is traceable to a specific requirement.

Risk-Ranked Observation Log

Findings classified by regulatory and product-quality impact, so your team knows what to address first.

Regulatory Traceability

Each observation cited to the applicable regulation, guideline, compendial chapter, or ISO clause.

Practical Remediation Guidance

Recommended corrective actions written by people who have implemented them, not generic instructions to revise an SOP.

Executive Summary

Issued when the review identifies a significant finding — such as a deviation, an OOS/OOT investigation adequacy issue, or a data integrity concern — that warrants senior management, quality council, or board-level attention. Not issued for routine reviews with no such finding.


Who We Work With

Pharmaceutical and biologics manufacturers relying on contract laboratories for raw material, in-process, release, or stability testing.

Virtual and emerging pharma companies without internal QC infrastructure, who need qualified oversight of every outsourced analytical activity.

Contract laboratories and CROs seeking independent readiness assessment ahead of a client audit or regulatory inspection.

Medical device and IVD manufacturers whose test method validation and data controls fall under quality system scrutiny.

Natural health product, cosmetics, and food manufacturers meeting Health Canada, US FDA, or ISO testing and specification requirements.

Organizations under regulatory pressure — responding to a Form 483 observation, warning letter, import alert, or a data integrity commitment already made to an agency.


Why Companies Choose ARIREX

Dedicated, Industry-Experienced Reviewers

Our reviewers are dedicated, industry-experienced professionals with real, hands-on laboratory and quality assurance backgrounds — not desk-based generalists. They have managed testing operations, signed off on batch release decisions, and defended their own data in front of regulators, before ever reviewing someone else's.

Practitioner-Led Review

Because our team has direct laboratory management and quality assurance experience, we assess method validation, investigation quality, and data governance with the judgement of people who have owned those decisions.

Genuinely Independent

ARIREX holds no commercial interest in the laboratories we assess and accepts no referral arrangements from them. Our finding is our finding.

Objective Evidence, Always

No finding is written on assumption or impression. Every observation in an ARIREX report is anchored to a document, a record, a data set, or a witnessed activity — the same standard a regulator applies.

Built for Defensibility

Our reports are structured to survive a real inspection, not to satisfy an internal checklist. If a finding cannot be supported with evidence, it does not go in the report.

A Global Auditor Network

ARIREX works with expert, dedicated, and experienced auditors across North America, Europe, and Asia — allowing us to assess laboratories where they operate and deliver consistent standards across a multi-site supply chain.

Frequently Asked Questions

Internal teams hold approval authority for the systems they assess, which is a structural limitation no amount of diligence overcomes. An independent reviewer has no history with the method, no relationship with the analyst, and no prior sign-off to defend. We frequently identify issues internal teams have looked past precisely because they see them every day.

No. Samples are sent to a third-party laboratory — either by you directly, or by ARIREX on your behalf, depending on what's agreed for the engagement. Either way, ARIREX does not operate the laboratory or hold a commercial relationship with it. Once the laboratory issues its data, you (or ARIREX, if arranged) forward the data package for independent review. We work exclusively from that data, which is what keeps the review genuinely independent.

Yes. ARIREX works with auditors across North America, Europe, and Asia, and conducts both on-site and remote assessments.

An initial scoping call, followed by access to the relevant records — method validation packages, SOPs, raw data, investigation files, or system configuration documentation, depending on scope. All access operates under a signed confidentiality agreement.

Either works. We can review your data package during a remote session, or you can send it to us directly for review — as soft copies (electronic files) or hard copies (physical documents), whichever is easier for your team and consistent with your data governance requirements.

Yes. We conduct independent assessments supporting responses to Form 483 observations, warning letters, and Health Canada inspection findings, and we review CAPA plans for adequacy before submission. ARIREX provides technical and compliance assessment; we do not provide legal advice or represent clients before regulatory agencies.

Yes. All engagements operate under a signed confidentiality agreement. We do not disclose client identities or findings, and we do not name clients in marketing materials without written permission.
