QUALITY CONTROL  
Use the following "Quick Quality Questions" as a simple, effective way to judge the accuracy of your testing laboratory.
  • Which proficiency testing programs do you participate in?
  • What are the processes and procedures in place to ensure accuracy?
  • Is your laboratory staffed with full-time employees, 52 weeks per year?
  • Is data transferred automatically from instruments to the reporting system?
Harris Laboratory utilizes a rigorous Quality Control (QC) program supported by an experienced and dedicated analytical team. This quality program is defined and measured with a Standard Operating Procedure (SOP) document. This SOP dictates the following action steps:
    Instrument set up, standardization and maintenance (fully documented).
    Preparation and implementation date for standards and extracting reagents.
    Testing and documentation of spike recoveries.
    Number of daily check samples (not less than 5% of billed samples).
    Number of daily replicate samples.
    Number of weekly re-analyzed samples.
    Number of blind check samples.
    Participation in outside operated proficiency testing programs.
The laboratory maintains a complete record of all supporting QC data for each report item. The aim of this program is simple: To provide error-free, substantiated, analytical data of precision and accuracy, governed solely by instrumental limitations.
