What's the difference between cleaning validation and verification?
Validation establishes documented evidence that a cleaning process consistently meets predetermined acceptance criteria, while verification involves ongoing checks to ensure the validated process remains effective during routine operations.
How do you determine worst-case locations for swab sampling?
We identify worst-case locations based on factors like product contact surface materials, geometry (hard-to-clean areas), process parameters, and historical data using risk assessment tools like FMEA.
What acceptance criteria do you use for TOC testing?
Criteria are established based on either: 1) product-specific calculations using HBEL/PDE values, 2) 10 ppm visible residue limit, or 3) 0.1% of normal therapeutic dose - whichever is most stringent for your product class.
Can you validate cleaning processes for cytotoxic products?
Yes, we specialize in cytotoxic cleaning validation using sensitive analytical methods (LC-MS/MS) and surface wipe sampling techniques capable of detecting nanogram-level residues of hazardous compounds.
How often should decontamination processes be revalidated?
We recommend annual revalidation, with additional testing after: equipment modifications, process changes, new product introductions, or when investigation results indicate potential cleaning process failures.
What does the Decontamination Validation service include?
Our service includes risk-based validation plans, residue quantification (TOC, HPLC, conductivity), microbial recovery studies, sporicidal efficacy validation, material compatibility assessments, and 3D contamination mapping.
Which regulatory standards do you follow?
We align with EU GMP Annex 1 (2022), FDA Cleaning Validation Guidance, PIC/S PI 006-3, ASTM E3106-18, ISO 14698-1/2, and USP <1072> for comprehensive compliance.
What deliverables can I expect?
You'll receive a validation master plan, analytical reports (TOC, swab, rinse), VHP cycle validation, 3D contamination mapping, cleaning verification matrices, material compatibility reports, and SOPs.
When should I use this service?
This service is ideal for validating new equipment, ensuring compliance in multi-product facilities, supporting aseptic manufacturing, or preparing for regulatory inspections.
How does Indivirtus ensure confidentiality?
We adhere to strict confidentiality protocols and industry best practices to protect your proprietary data throughout the validation process.
What makes your validation approach unique?
Our risk-based approach, combined with advanced analytics, worst-case testing, and tailored protocols, ensures robust validation of cleaning processes for both sterile and non-sterile environments.
