Specific program areas include: accreditation and registration/certification, blind Quality Control (QC) submittal and program oversight for LS and its contract laboratories, coordination and maintenance of the proficiency testing programs, document control, training, internal and external audits, oversight of the LS environmental management program, and corrective and preventive actions.
Customer Audits & Tours
Customers and clients of LS are encouraged to schedule and perform an audit of any of the LS areas. This service allows the customer to review internal LS protocols and records that may be specific to their program areas so that they can gain a better understanding of the types of controls and procedures used to maintain accurate, reliable, scientifically sound and legally defensible data. LS also welcomes customer tours through the laboratory facilities. Customers interested in arranging a tour of the LS facilities or conducting an audit should send their request via email to the LS hotline:
The LS is dedicated to the generation of quality data in support of Total Customer Satisfaction. Customer satisfaction surveys are sent with random packets of results forwarded by the CSD. Completed, returned forms are reviewed by the LS Management Review Team (MRT). If a complaint is received, one of the Quality Assurance (QA) officers will initiate an investigation through the use of the LS Corrective Action Report (CAR). To close the loop and ensure the effectiveness of our CAR process, customers may be contacted by one of the QA officers when the investigation is completed. Customers may receive a more detailed annual survey via e-mail. Customer feedback is reviewed and if possible, suggestions received are implemented.
The LS QAD staff are available for consultation in the following areas: planning projects, data review, proficiency testing results, accreditation information, method implementation requests, audits, and training.
