How the checker decides

The checker weighs the same things a careful flooring team asks about. If JavaScript is off in your browser, this table covers the same ground.

Factors that make slab moisture testing more or less important
Factor	Points toward testing	Points away (still check)
Spec or instructions	They name a test method or a moisture limit. Then testing is simply part of the job.	Nothing mentions moisture (rare for glue-down systems).
Flooring system	Glue-down wood, glue-down resilient, coatings, anything that bonds to the slab.	Stretched-in carpet; tile in thinset with no moisture-sensitive membrane.
Adhesive	An adhesive or primer goes on the concrete.	Nothing bonds to the slab.
Slab age	New or recent pours; unknown history.	Older slab with a dry track record.
History	Past cupping, adhesive failure, white deposits, odor, leaks or flooding.	No known issues.
Building conditions	Testing needs the building at service conditions, so HVAC start-up affects timing.	HVAC already running normally.

What the checker cannot do

It cannot tell you whether a slab passes. Only a test, compared with the selected products’ written limits, can do that.
It does not replace the flooring, adhesive or coating manufacturer’s instructions, or your project specification.
It is about planning before installation. If an installed floor has already failed, a pre-installation moisture test is not designed to explain why.
