What are Cutoff Levels?
Whether you are taking a drug test or administering a drug test, it’s important to understand the Cut-off Levels and what they mean in the context of the drug test. Every substance tested in 12 Panel Now’s Drug Testing cups have a different cut-off level so understanding the levels is essential.
In a drug test, a negative result is defined as a specimen that does not indicate a level of drugs at, or above, the specified concentration of a drug. That specified concentration used is called the cut-off level. A specimen that contains drugs at or above the determined cut-off level is positive.
If you are interested in locating the cut-off level for your product, 12 Panel Now provides information with each shipment. Each package comes with a Cut-off level list located on the second page of the pamphlet shipped.
