An abbreviated test can be performed when

• A. The owner agrees
• B. The owner agrees; all components tested are the same in each room equivalent; the component tested is positive for lead based paint in the first five rooms tested.
• C. All components tested are the same in each room equivalent
• D. The component tested is positive for lead based paint in the first five rooms tested.

Answer: (B)

Abbreviated testing relies on a representative sampling approach: if rooms are equivalent in the components being tested, and you have confirmed lead in a representative subset, you can extend that conclusion to the other similar components without testing every item. But this is only acceptable when you have the property owner’s explicit consent to proceed with this streamlined approach, and when the initial samples from the first set of rooms show lead-based paint. The owner’s agreement ensures you’re acting with permission, the room equivalence ensures the sample is representative, and the positive result in the first five rooms provides the evidence needed to extrapolate to the rest. When any of these elements is missing, abbreviated testing isn’t appropriate.
