Getting to the Bottom of What It All Means
A qualitative assay (reporting only Positive/Negative results) cannot be used to determine the sensitivity of a quantitative assay (which reports numbers of detected organisms at levels as low as 10 cells/gram of stool).

They are not intended to report low levels of organisms and cannot do so. A negative result does not rule out that the organism is present at levels below disease levels.
