Directory of Accredited Laboratories

Listed below are all NVLAP Laboratory Accreditation Programs (LAPs). Click on the program name to view an index of laboratories accredited by NVLAP for that program.

This directory was last updated on July 27, 2004. Information is updated on a quarterly schedule, which is based upon the four accreditation renewal dates. New and updated scopes of accreditation are posted within 30 days of the end of a renewal cycle; e.g., updated scopes of accreditation for renewing laboratories with an expiration date of June 30, 2004, will be posted on the web site no later than the end of July 2004. This window is necessary to ensure that all renewals have been processed correctly and expired accreditations have been purged from the information system.
