Q3 Innovations DrugHAWK ECO Cup User Manual
Page 3
Forty (40) clinical samples for each drug were run using each strip contained within
ECO CUP™
One Step Drug Test by an untrained operator at a Professional Point of Care site. Based on
GC/MS data, the untrained operator obtained statistically similar Positive Agreement, Negative
Agreement and
Overall Agreement rates as trained laboratory personnel.
*Note: TCA was based on HPLC data.
Reproducibility
Reproducibility studies were carried out using commercially available standards. Each standard
was diluted in normal, drug-free urine to give the appropriate concentration. Each specimen, at
each concentration of analyte, was tested four times daily, in duplicate, for five consecutive days.
A total of 40 determinations were made at each concentration. The results are given below:
membrane wicking and correct procedural technique.
LIMITATIONS
1. The
ECO CUP™ One Step Drug Test
provides only a qualitative, preliminary analytical result.
A secondary analytical method must be used to obtain a confirmed result. Gas
chromatography/mass spectrometry (GC/MS) is the preferred confirmatory method.
2. There is a possibility that technical or procedural errors, as well as other interfering substances
in the urine specimen may cause erroneous results.
3. Adulterants, such as bleach and/or alum, in urine specimens may produce erroneous results
regardless of the analytical method used. If adulteration is suspected, the test should be
repeated with another urine specimen and a new test device.
4. A Positive result does not indicate intoxication of the donor, the concentration of drug in the
urine, or the route of drug administration.
5. 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.
6. Test does not distinguish between drugs of abuse and certain medications.
7. A positive test result may be obtained from certain foods or food supplements.
PERFORMANCE CHARACTERISTICS
Accuracy
A side-by-side comparison was conducted using
ECO CUP™ One Step Drug Test and other
commercially available rapid drug tests. Testing was performed on 120 samples per drug type. All
the presumptive positive and negative results were confirmed by GC/MS. The following
compounds were quantified by GC/MS and contributed to the total amount of drugs found in
presumptive positive urine samples tested.
The following results are tabulated from these clinical studies:
