Limitations
The Alltest Rapid Fentanyl Test provides only a qualitative, preliminary result. A secondary analytical method must be used to obtain a confirmed result. GC/MS or LC/MS is the preferred confirmatory method.
It is possoble that technical or procedural errors, as well as other interfering substances in the urine specimen may cause erroneous results.
A confirmed positive result indicates presence of the drug but does not indicate the level of intoxication, administration route or concentration in
urine.
A negative result may not necessarily indicate drug-free urine. Negative results can be obtained when drug is present but below the cut-off level of the test.
Test does not distinguish between drugs of abuse and certain medications.
