Mold test mistakes:

This document describes how to avoid common mistakes people make when trying to find mold and test for mold in buildings, such as testing only the "black mold" on surfaces or relying only on air tests to screen buildings for problem mold.

These mistakes amount to collecting mold test samples in the wrong place, or failing to collect mold test samples in other important places.
