Lab Method Validation & Verification

Your instrument is installed. Is the laboratory ready? We help scope the right studies, review the data, and build documentation that clearly shows what was tested and why.

Part of Connexis Laboratory Compliance Consulting, led by Rick Peluso.

Installed isn’t the same as ready.

The demonstration went well and a launch date is on the calendar. Before the first patient result is reported, someone has to answer a broader question: what establishes that this laboratory is ready to use this system for its intended testing?

That takes more than an instrument that powers on and produces results. It takes clear study responsibilities, suitable evidence, qualified review, and an operating process the lab can maintain.

Technical support includes

  • ✓ Verification of manufacturer-established performance specifications, as applicable
  • ✓ Validation planning for laboratory-developed or modified methods, where applicable
  • ✓ Study protocols, acceptance criteria, and data collection templates
  • ✓ Statistical data reduction and review
  • ✓ Deviation investigation, technical summaries, and approval packages
  • ✓ Support for instrument changes, new platforms, and test-menu expansion

Verification or validation? It depends on the test system.

Identify the instrument, assays, intended use, regulatory status, and any modifications before deciding what data to collect.

Verification

Unmodified, FDA-cleared or approved nonwaived systems

Before reporting patient results, the lab confirms the manufacturer’s performance specifications in its own hands — including accuracy, precision, reportable range, and the appropriateness of reference intervals.

Validation

Modified methods and laboratory-developed tests

The lab establishes performance specifications itself, which can require additional characteristics and a more extensive study design, defined against the specific method and intended use.

Waived testing shouldn’t automatically be put through the nonwaived verification framework, and a study package that fits one system shouldn’t be assumed to fit every method.

From plan to approval

Settle the analysis plan before testing begins — so you don’t discover later that the concentrations, comparison method, or records can’t support the conclusion you need.

01

Plan

Define the performance characteristic, materials, acceptance criteria, and reviewers before collecting results.

02

Execute

Use a fit-for-purpose protocol, records, and data review workflow.

03

Document

Present results, deviations, limitations, conclusions, and approvals in a coherent file.

04

Maintain

Recommend updates when methods, assays, or operating conditions change.

Follow the result beyond the instrument.

An analyzer can display the right result while an interface sends the wrong unit or maps it to the wrong field. The analyzer’s performance data wouldn’t catch that. Implementation planning covers the whole workflow — procedures, quality processes, staff preparation, result reporting, and escalation — so nothing is left to whoever happens to notice it near launch.

And when results are unexpected, they trigger an evaluation. Changing acceptance criteria after seeing the data just to get a passing conclusion defeats the purpose of the study.

Who delivers what

Manufacturer

Installation, training, and technical materials — with the scope of that support confirmed up front.

Your laboratory

Study materials, testing, technical judgments, and the required approvals.

Our team

Planning, data reduction, deviation review, and a documented file your lab understands and owns.

Common questions

What’s the difference between method verification and validation?

Verification confirms that an unmodified, FDA-cleared or approved test performs to the manufacturer’s specifications in your lab. Validation establishes performance for laboratory-developed or modified methods. Requirements differ, so studies are scoped to the specific test system.

Can you help with data reduction only?

Yes. If your team has already run the study, we can review and reduce the data, investigate deviations, and help assemble the approval package. Your lab still needs to understand the study, the results, and their limitations.

We’re bringing a new analyzer online — when should we call?

Before collecting results. Defining objectives and acceptance criteria up front avoids re-running studies.

Does a new assay on an existing instrument need a new study?

Often, yes. A new assay, a modified process, or a change in intended use may require a fresh evaluation. A well-organized original file gives you a starting point for understanding what was previously established.

Have a new instrument or method coming online?

Tell us the system and timeline so we can define an appropriate support project.

Rick will follow up personally to talk through the study.
