Testing Services / Pharmaceutical
Microbiological and Analytical testing is crucial to ensuring the safety, quality, and regulatory compliance of pharmaceutical products. These tests detect harmful contaminants and verify the identity, purity, potency, and stability of drugs, safeguarding public health and ensuring consistent product quality. Conducting these tests in-house can be resource-intensive and complex. By outsourcing to CLS who have significant experience and advanced capabilities, pharmaceutical companies can ensure thorough, reliable testing while focusing on their core competencies. Partnering with CLS for microbiological and analytical testing not only guarantees compliance with stringent regulatory standards but also streamlines the entire drug development and manufacturing process.
