California certification means the laboratory appears on that official list; a laboratory may be physically located outside California. Certification does not confirm mail-in or residential service. Ask the lab before collecting a sample.
Labs for home testing: 209 · Commercial and industrial: 225 · Plant and utility: 26
Choosing a test?
Decide what to ask for before you filter this list. Certification alone does not confirm that a lab accepts household samples.
