How to Choose the Right Analytical Testing Lab: 7 Critical Questions to Ask

When it comes to quality, compliance, and accuracy—choosing the right analytical testing lab can make or break your product’s credibility. Whether you're in pharma, food & beverages, cosmetics, or environment monitoring, here are 7 critical questions you must ask before partnering with a testing laboratory: 1. Is the lab NABL-accredited and ISO 17025 compliant?

An accredited lab ensures traceability, accuracy, and quality of results. ISO 17025 accreditation proves technical competence and process reliability.

2. What is their testing scope?

Check if the lab offers the testing services you need—chemical, microbiological, instrumental, water, stability, or method validation—across your industry.

3. Do they use certified reference materials (CRMs)?

CRMs ensure traceable, accurate, and internationally recognized testing results. Labs that rely on CRMs follow the highest standard in method validation.

4. Are their methods validated and compliant?

A trusted lab should follow validated methods per international guidelines (e.g., ICH, USP, BIS) and be open about their SOPs and instrumentation.

5. How experienced is the technical team?

Expertise matters. Look for a team with pharmaceutical analysts, chemists, and QA/QC professionals who understand regulatory requirements deeply.

6. What’s their turnaround time and communication flow?

Efficiency is key. Ask about report delivery timelines, project tracking, and support during audits or regulatory queries.

7. Can they support audits and regulatory documentation?

Choose a lab that can confidently back your compliance needs with proper documentation, CoAs, and data integrity assurance.
