When in doubt, test the area. Results may indicate a need for additional testing in upper areas.

7. Illinois Protocol ANSI/AARST MAMF-2012 Section 422.130 f)
3.0 Where to Test
3.4 On the upper floors, conduct a measurement in at least one apartment on each floor; include measurements in at least 10 % of the dwellings on each of the higher floors.
