Quality Assurance Support

Tower Mains prides itself on offering flexible, credible and cost-effective quality assurance unit support services. We provide QA resource when and where you need it – from short ad hoc projects to long term QA collaborations across the regulatory and non-regulatory field.


Independent audits are beneficial in assuring clients that work is being performed in accordance with their expectations and requirements. To support this, Tower Mains provides audit services on a study and non-study specific basis. For example:

  • Study based Audits

    • Study plan and amendment review
    • Critical phase inspections
    • Raw data and report audit
  • Process Based Inspections
  • Facility Based Inspection

    • A facility Inspection should be carried out on at least an annual basis to ensure continuing compliance with GLP and the requirements of Company SOPs. It should look at the entire organisation, specifically those aspects of which are not covered in the study or process inspections.
