The following sets of links lead to program specific lists of AIHA Laboratory Accreditation Programs, LLC accredited laboratories. The lists are sortable on a number of headers, including State, Lab Name, Phone Number (Area Code), and Commercial Availability (fee for sampling services).  Double-clicking on a lab's name in the list will open up the details of the laboratory's scope of accreditation.


Please note that a laboratory for which a published standard method (e.g., NIOSH 7082) is listed may have been assessed and accredited for that method as modified by the laboratory, rather than as published. Always contact the laboratory to verify exact procedures and ensure suitability to your needs.
