Asbestos testing must be performed by accredited laboratories and qualified professionals. Reliable sources include:
- NIST NVLAP-accredited laboratories – Search the National Voluntary Laboratory Accreditation Program directory at nist.gov/nvlap for labs certified for PLM (bulk) and/or TEM (air) asbestos analysis.
- State/local environmental agencies – Many offer testing services or maintain lists of certified contractors; they also clarify regulatory requirements.
- Private accredited laboratories – Can analyze bulk samples you collect (with strict safety protocols) or send technicians. Verify NVLAP or AIHA-LAP accreditation.
- Environmental consulting firms – Specialize in hazardous building assessments; often provide sampling, analysis coordination, and management plans as a package. Choose firms with certified asbestos inspectors (AHERA) and project designers.
Critical: Do not disturb suspect material to collect samples yourself. Improper sampling releases fibers and may invalidate results. Hire a trained professional for sampling, chain-of-custody documentation, and result interpretation.
