Microbiology Testing

A complete array of GMP microbiology services including sterility, endotoxin, bioburden, microbial limits and disinfectant efficacy studies. Learn more.

Extensive microbiology and sterility testing to support bio/pharmaceutical and medical device product and patient safety from SGS.

Characterizing pharmaceutical ingredients in bio/pharmaceutical and medical devices is essential for ensuring final product quality, preventing harm to the patient and avoiding product spoilage.

All regulatory authorities expect manufacturers to characterize the microbial quality of their pharmaceutical substances, both active and excipient. Pharmaceutical manufacturers are also required to characterize their drug products’ manufacturing and handling processes to control or eliminate chances of contamination.

SGS can help you meet regulatory requirements and protect patient safety.

Our microbiologists have a wealth of technical knowledge and the expertise to develop and apply USP, Ph. Eur. and other international methods to a wide variety of biologics, traditional pharmaceuticals and medical devices. They will help you to ensure product quality and safety, from development through final product launch and post market support.
