Quality Assurance Reviews


Performance/System Audits.
Audits are a fundamental component of a quality system. Internal audits are performed at least annually. In addition, CSL analyzes blind proficiency samples supplied by the state of NY twice per year to maintain our NELAP accreditation.

External Audits. These audits include regulatory agencies, customers, or their representatives. CSL undergoes on-site audits by the state of Pennsylvania (every 3 years), the FDA (every 2 years), and various clients for cGLP/cGMP compliance. All clients are welcome and encouraged to visit our facility. During customer audits confidentiality is a priority. Only records for that client and those records which do not violate other clients’ confidentiality shall be reviewed.
