Adventitious agent and mycoplasma testing services from SGS – biologics safety testing to ensure that your cell cultures, virus stocks and final products are certified free from contaminating agents, such as endotoxins and viruses.


During the development of your biopharmaceutical products, the threat of cell culture contamination by adventitious agents such as mycoplasma, endotoxins and viruses, should not be underestimated. We offer you comprehensive testing for a range of contaminants at every stage of your drug development and production process.

Why choose adventitious agent and mycoplasma testing services from SGS?

Our testing services include endotoxin testing, biologics safety testing, mycoplasma testing and in vitro adventitious virus assays.

We can help you:

  • Improve your quality control measures for biopharmaceutical product development
  • Gain precise data to ensure the best possible performance from your product
  • Detect mycoplasma, which can alter virtually every cellular process, including hybridoma selection rates, protein and nucleic acid synthesis, and immunogenicity and chromosomal damage
  • Identify viral contamination to prevent the distortion of biomedical and biotechnological product research and clinical evaluation, and avoid productivity losses in biological manufacturing
  • Reveal endotoxins to prevent their presence in the end product, avoiding the risk of inflammatory responses in patients
  • Ensure that your biopharmaceutical products meet international and local regulatory requirements
