How does OneChoice handle organisms or resistance genes that were not detected or not tested?

“Not detected” and “not tested” are not the same thing, and OneChoice treats them differently when the laboratory sends that information.

Tested and not detected

This means the assay did not find that specific target within the limits of the test. OneChoice may account for the fact that testing was performed and no relevant target was reported. It does not mean that every possible organism or resistance mechanism has been ruled out.

Not tested

This means the answer is unknown. OneChoice cannot assume an organism or resistance mechanism is absent simply because it was not included in the panel, culture, or susceptibility testing.

Tested but not sent to Arkstone

OneChoice cannot use information it did not receive. Compare the OneChoice Report with the complete laboratory result to see what testing was performed.

Every test has a target list, detection limits, specimen requirements, and other limitations. OneChoice uses the available results to support focused treatment; it does not recommend broad antibiotics for every theoretical organism that might not have been tested.

Review the assay's limitations, the patient's presentation, and local epidemiology when deciding whether additional testing or empiric coverage is appropriate. OneChoice Plus shows available information about resistance genes tested for the specimen.
