List of NGSP Certified Laboratories (updated 9/21, listed by date certified)

The NGSP has certified the following laboratories as having documented traceability to the Diabetes Control and Complications Trial Reference Method. Laboratories are awarded Certificates of Traceability for successfully completing bias testing using specific methods, reagent lots, calibrator lots and instrumentation. The certification criteria for Level II Laboratory certification are the same as that for manufacturers. For Level I laboratories, the certification criteria are more stringent. Traceability to the DCCT applies only to results from fresh blood samples unless otherwise specified. Analysis of processed (e.g. lyophilized) material may be subject to matrix effects and any comparisons to the DCCT using results from processed specimens should be made with caution.
