"Your laboratory and the data they produce are only as good as the processes by which they acquire this data and conform to your specific data needs."     Mike Stewart Principal, eDATApro	Laboratory audits are the cornerstone of the laboratory selection process. In order to maintain high levels of data quality, standards and criteria must be established, monitored, and reviewed to ensure that your laboratory can consistently produce defensible data. It is important that a laboratory's Quality Assurance program be verified during the laboratory selection process through on-site evaluation. The on-site evaluations conducted by eDATApro consist of intensive surveys that examine the following areas: organization laboratory facilities personnel qualifications sample receipt and handling performance of analytical procedures quality assurance records and data reporting project management/client services training procedures safety eDATApro typically evaluates a laboratory's performance in these areas by tracking a sample analyzed by the laboratory from the point of entry to the final report. All staff members of eDATApro worked for an environmental laboratory at some point during their professional career; therefore, our experience in this process is unmatched. An audit report detailing laboratory deficiencies and areas for improvement is issued as soon as possible after the on-site inspection.
