A rapid one step test for the qualitative detection of drug of abuse and their principal metabolites in human urine at specified cut off level.
Material Required But Not Provided
For healthcare professional use only. For in vitro diagnostic use.
Collect a urine sample in the urine cup. Urine specimens may be refrigerated (2-8°C) and stored up to forty-eight hours. For longer storage,
One Step Multi-Drug Urine Test Panel is rapid urine screening test. The test is a lateral flow, one-step immunoassay for the qualitative detection
of specific drugs and their metabolites in human urine at the following cut off concentrations:
Bring frozen or refrigerated samples to room temperature before testing. Previously frozen or refrigerated samples should be well mixed before
analysis. Cloudy specimens should be centrifuged before analysis. Use only clear aliquots for testing.
Test must be in room temperature (10ºC to 30ºC).
1. Open the sealed pouch by tearing along the notch. Remove the test device from the pouch.
2. Hold the one side of the device with one hand. Use the other hand to pull out the cap and expose the absorbent end.
3. Immerse the absorbent end into the urine sample about 10 seconds. Make sure that the urine level is not above the “MAX” line printed on the
4. Lay the device flat on a clean, dry, non-absorbent surface.
5. Read the result at 5 minutes. Do not read after 5 minutes.
This assay provides only a preliminary test result. A more specific alternative chemical method must be used in order to obtain a confirmed
analytical result. Gas chromatography/mass spectrometry (GC/MS) is the preferred confirmatory method. Clinical consideration and professional
judgment should be applied to any drug of abuse test result, particularly when preliminary results are positive.
INTERPRETATION OF RESULTS
One Step Multi-Drug Urine Test Panel is a competitive immunoassay that is used to screen for the presence of drugs of abuse in urine. It is

If a color band is not visible in each of the control region or a color band is only visible in each of the test region, the test is invalid. Another test
should be run to re-evaluate the specimen. Please contact the distributor or the store, where you bought the product, with the lot number.
WARNINGS AND PRECAUTIONS
There is no meaning attributed to line color intensity or width.
Users should follow the appropriate federal state, and local guidelines concerning the frequency of assaying external quality control materials.
Though there is an internal procedural control line in the test device of Control region, the use of external controls is strongly recommended as
good laboratory testing practice to confirm the test procedure and to verify proper test performance. Positive and negative control should give the expected results. When testing the positive and negative control, the same assay procedure should be adopted.
1. This test has been developed for testing urine samples only. The performance of this test using other specimens has not been substantiated.
2. Adulterated urine samples may produce erroneous results. Strong oxidizing agents such as bleach (hypochlorite) can oxidize drug analyses. If
a sample is suspected of being adulterated, obtain a new sample.
3. This test is a qualitative screening assay. It is not designed to determine the quantitative concentration of drugs or the level of intoxication
4. It is possible that technical or procedural errors, as well as other interfering substances in the urine specimen may cause erroneous results.
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
6. The test result does not distinguish between drugs of abuse and certain medicines.
7. A positive result might be obtained from certain foods or food supplements.
1200 (eighty of each drug) clinical urine specimens were analyzed by GC-MS and by each corresponding One Step Multi-Drug Urine Test Panel.
Each test was read by three viewers. Samples were divided by concentration into four categories: less than half the cutoff, near cutoff negative,
near cutoff positive, and high positive. Results were as follows:
Precision and Sensitivity
To investigate the precision and sensitivity, for AMP, BAR, BZO, COC, THC, MTD, MET, MDMA, MOP, OPI, PCP and TCA, each drug samples
were analyzed at the following concentrations: - 50%cutoff, - 25%cutoff, cutoff, +25%cutoff and + 50%cutoff. All concentrations were confirmed
with GC-MS. Each concentration was tested using three different lots of the corresponding the drug of abuse test. Thirty samples were analyzed
at each concentration, and each result was read by three viewers, for a total of 90 results per concentration per lot of the corresponding the drug
For OXY, BUP and PPX, precision and sensitivity was assessed with three lots tested by three individuals over five consecutive days. In the study,
seven separate normal urine samples were spiked with each drug to the following concentrations: Zero, -50% cutoff, -25% cutoff, cutoff, +25%
cutoff, +50% cutoff and +100% cutoff. Level of the each drug for these samples was confirmed by GC/MS. Then each sample was divided into 75
aliquots that were further divided into 3 sets of 25 (one set for each lot). Each of the three operators tested 5 aliquots at each concentration for

of detection for the specified drugs or metabolites.
3,4-Methylenedioxymethamphetamine HCl(MDMA) 500
From the results above, it is clear that One Step Multi-Drug Urine Test Panel resists well against interference from these substances.
Effect of Urinary Specific Gravity
5 urine samples with density ranges (1.000-1.035) are collected and spiked with each drug at 50% below and 50% above cutoff level. One Step Multi-Drug Urine Test Panel was tested in duplicate. The results demonstrate that varying ranges of urinary specific gravity do not affect the test
Effect of Urinary PH
The pH of an aliquot negative urine pool is adjusted to a pH range of 4 to 9 in 1 pH unit increments and spiked with morphine at 50% below
and 50% above cutoff levels. One Step Multi-Drug Urine Test Panel was tested in duplicate. The result demonstrate that varying ranged of PH
do not interfere with the performance of the test.

MEANING OF SYMBOLS ON PACKAGE
Considering the complexity of clinical urine specimens and the possibility that various urine specimens contain potentially interfering substances,
we simulated above situations by adding the potentially interfering substances to a certain concentration as specimen. The following components
show no cross-reactivity when tested with One Step Multi-Drug Urine Test Panel at a concentration of 100 g/ml.
