We develop and validate stability indicating test methods for new drugs. With sustainable partnerships in mind, we promote analytical continuity in testing impurity profiles of new drug substances and corresponding new drug products. This is a key component of successful CMC section of regulatory submissions.
All analytical testing activities performed at KABS are executed in cGMP compliant facilities audited by Health Canada, USFDA, European QPs. A Continuous training program in cGMP guidelines and testing procedures is the cornerstone of our compliance.
Originally developed as a local reference testing laboratory, KABS steadily improved its facilities, instrumentation and quality systems in response to demands for advanced and integrated analytical support, worldwide. KABS is a WHO (World Health Organization) prequalified Quality Control Laboratory.
