Laboratory Certification—A recognition of testing performance
Laboratory Certification is a means of determining the performance of laboratories conducting testing, measurement and calibration.  It provides formal recognition that a laboratory has implemented a laboratory management system, thus providing a ready means to customers to identify and select reliable testing, measurement and calibration services to meet their needs.

To maintain this certification, laboratories are re-evaluated periodically by the Guyana National Bureau of Standards to ensure that there is continual compliance with the requirements and to check that their standard of operation is being maintained.  The laboratory may also be required to participate in relevant proficiency testing programmes between reassessments, as a further demonstration of technical performance.

Laboratory Certification—A bench mark for performance

Laboratory Certification benefits laboratories by allowing them to determine whether they are performing their work efficiently in keeping with the requirements of the National Standard. Certification provides laboratories with a benchmark for maintaining the laboratory management system and improving the quality of laboratory services offered to customers.
