Choose the right level of testing
Screening strips and qualifying laboratory tests answer different questions. We show what each covers and what it can't establish.
We don't have a vetted test offer here yet
We don't list a test here until it's been checked against our own standard — so there's nothing to buy on this page right now. That doesn't mean testing isn't the right next step. The guides below explain what each kind of testing actually covers and how to find one yourself.
Testing guides
A screening strip suggests; a qualifying laboratory test establishes. For a named contaminant, real-estate or regulatory need, only a qualifying lab test is appropriate.
