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). The BioFire and Meridian assays are designed to detect only high levels of organisms, intended to correlate to acute disease states. 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.
