A rapid, one step screen test for the simultaneous, qualitative detection of multiple drugs and metabolites in human
urine. For medical and other professional in vitro diagnostic use only.
INTENDED USE & SUMMARY
Urine based screen tests for multiple drugs of abuse range from simple immunoassay tests to complex analytical
procedures. The speed and sensitivity of immunoassays have made them the most widely accepted method to screen
urine for multiple drugs of abuse.
The Multi-Drug One Step Screen Test Panel (Urine) is a lateral ow chromatographic immunoassay for the qualitative
detection of following drugs without the need of instruments.
This test will detect other related compounds, please refer to the Analytical Specicity table in this package insert.
Congurations of the Multi-Drug One Step Screen Test Panel (Urine) come with any combination of the above
listed drug analytes with or without S.V.T. This assay provides only a preliminary analytical test result. A
more specic alternate chemical method must be used in order to obtain a conrmed analytical result. Gas
chromatography/mass spectrometry (GC/MS) is the preferred conrmatory method. Clinical consideration
and professional judgment should be applied to any drug of abuse test result, particularly when preliminary
positive results are indicated.

S.V.T. SUMMARY
Each S.V.T. strip contains chemically treated reagent pads. Three to ve minutes following the activation of the reagent
pads by the urine sample, the colors that appear on the pads can be compared with the printed color chart card. The
color comparison provides a semi-quantitative screen for any combination of oxidants/pyridinium chlorochromate
(PCC), specic gravity, pH, nitrite, glutaraldehyde and creatinine in human urine which can help assess the integrity
of the urine sample.
PRINCIPLE
The Multi-Drug One Step Screen Test Panel (Urine) is an immunoassay based on the principle of competitive binding.
Drugs which may be present in the urine specimen compete against their respective drug conjugate for binding sites
on their specic antibody.
During testing, a urine specimen migrates upward by capillary action. A drug, if present in the urine specimen below
its cut-o concentration, will not saturate the binding sites of its specic antibody coated on the particles. The antibody
coated particles will then be captured by the immobilized drug conjugate and a visible colored line will show up in the
test line region of the specic drug strip. The colored line will not form in the test line region if the drug level is above its
cut-o concentration because it will saturate all the binding sites of the antibody coated on the particles.
A drug-positive urine specimen will not generate a colored line in the specic test line region of the strip because of
drug competition, while a drug-negative urine specimen or a specimen containing a drug concentration less than the
cut-o will generate a line in the test line region. To serve as a procedural control, a colored line will always appear at
the control line region indicating that proper volume of specimen has been added and membrane wicking has occurred.
S.V.T. PRINCIPLE
Adulteration is the tampering of a urine specimen with the intention of altering the test results.
The use of adulterants can cause false negative results in drug tests by either interfering with the screening test and/
or destroying the drugs present in the urine. Dilution may also be employed in an attempt to produce false negative
drug test results.
One of the best ways to test for adulteration or dilution is to determine certain urinary characteristics such as pH and
specic gravity and to detect the presence of oxidants/PCC, specic gravity, pH, nitrite, glutaraldehyde and creatinine
in urine.
• Oxidants/PCC (Pyridinium chlorochromate) tests for the presence of oxidizing agents such as bleach and hydrogen
peroxide. Pyridinium Chlorochromate is a commonly used adulterant.2 Normal human urine should not contain oxidants
or PCC.
• Specic gravity tests for sample dilution. The normal range is from 1.003 to 1.030. Values outside this range may be
the result of specimen dilution or adulteration.
• pH tests for the presence of acidic or alkaline adulterants in urine. Normal pH levels should be in the range of 4.0 to
9.0. Values outside of this range may indicate the sample has been altered.
• Nitrite tests for commonly used commercial adulterants such as Klear or Whizzies. They work by oxidizing the major
cannabinoid metabolite THC-COOH.
3
Normal urine should contain no trace of nitrite. Positive results generally indicate
the presence of an adulterant.
• Glutaraldehyde tests for the presence of an aldehyde. Adulterants such as UrinAid and Clear Choice contain
glutaraldehyde which may cause false negative screening results by disrupting the enzyme used in some immunoassay
tests.2 Glutaraldehyde is not normally found in urine; therefore, detection of glutaraldehyde in a urine specimen is
generally an indicator of adulteration.
• Creatinine is a waste product of creatine, an amino acid contained in muscle tissue and found in urine.
1
A person
may attempt to foil a test by drinking excessive amounts of water or diuretics such as herbal teas to “ush” the system.
Creatinine and specic gravity are two ways to check for dilution and ushing, which are the most common mechanisms
used in an attempt to circumvent drug testing. Low creatinine and specic gravity levels may indicate dilute urine. The
absence of creatinine (< 5 mg/dL) is indicative of a specimen not consistent with human urine.
REAGENTS
Each test contains specic drug antibody-coupled particles and corresponding drug-protein conjugates. A goat antibody
is employed in each control line.

PRECAUTIONS
• For medical and other professional in vitro diagnostic use only. Do not use after the expiration date.
• The test panel should remain in the sealed pouch until use.
• All specimens should be considered potentially hazardous and handled in the same manner as an infectious agent.
• The used test panel should be discarded according to local regulations.
STORAGE AND STABILITY
Store as packaged in the sealed pouch either at room temperature or refrigerated (2-30°C). The test panel is stable
through the expiration date printed on the sealed pouch. The test panel must remain in the sealed pouch until use. DO
NOT FREEZE. Do not use beyond the expiration date.
SPECIMEN COLLECTION AND PREPARATION
Urine Assay
The urine specimen must be collected in a clean and dry container. Urine collected at any time of the day may be used.
Urine specimens exhibiting visible precipitates should be centrifuged, ltered, or allowed to settle to obtain a clear
supernatant for testing.
Specimen Storage
Urine specimens may be stored at 2-8°C for up to 48 hours prior to testing. For prolonged storage, specimens may
be frozen and stored below -20°C. Frozen specimens should be thawed and mixed well before testing. When tests
include S.V.T., storage of urine specimens should not exceed 2 hours at room temperature or 4 hours refrigerated prior
to testing. For best results, test specimens immediately following collection.
MATERIALS
Materials Provided
• Test panels • SVT/Adulterant color chart (if applicable) • Package insert
Materials Required But Not Provided
• Specimen collection container • Timer
DIRECTIONS FOR USE
Allow the test panel, urine specimen,
and/or controls to equilibrate to room
temperature (15-30°C) prior to testing.
1. Remove the test card from the sealed
pouch and use it as soon as possible.
Remove the cap from the end of the test
card. With arrows pointing toward the
urine specimen, immerse the strip(s)
of the test card vertically in the urine
specimen for at least 10-15 seconds.
Immerse the strip(s) to at least the
level of the wavy lines, but not above
the arrow(s) on the test card.
2. Replace the cap and place the test
card on a non-absorbent at surface,
start the timer and wait for the colored
line(s) to appear.
3. Read the adulteration strip between 3
and 5 minutes by comparing the colors
on the adulteration strip to the enclosed
color chart. If the result indicates adulteration, do not interpret the drug test results. Either retest the urine or collect
another specimen.
4. Read the drug strip results at 5 minutes. Do not read results after 10 minutes.
INTERPRETATION OF RESULTS
(Please refer to the illustration above)
NEGATIVE:* A colored line in the control line region (C) and a colored line in the test line region (T) for a specic
drug indicate a negative result. This indicates that the drug concentration in the urine specimen is below the designated
cut-o level for that specic drug.
*NOTE: The shade of color in the test region (T) may vary, but it should be considered negative whenever there is
even a faint colored line.
POSITIVE: A colored line in the control line region (C) but no line in the test line region (T) for a specic drug
indicates a positive result. This indicates that the drug concentration in the urine specimen exceeds the designated
cut-o for that specic drug.

ENGLISH
INVALID: Control line fails to appear. Insucient specimen volume or incorrect procedural techniques are the most
likely reasons for control line failure. Review the procedure and repeat the test using a new test panel. If the problem
persists, discontinue using the lot immediately and contact your local distributor.
SVT/ADULTERANT INTERPRETATION
(Please refer to the color chart)
Semi-quantitative results are obtained by visually comparing the reacted color blocks on the strips to the printed color
blocks on the color chart. No instrumentation is required.
QUALITY CONTROL
A procedural control is included in the test. A colored line appearing in the control line region (C) is considered an internal
procedural control. It conrms sucient specimen volume, adequate membrane wicking and correct procedural technique.
Control standards are not supplied with this kit; however, it is recommended that positive and negative controls be tested
as good laboratory practice to conrm the test procedure and to verify proper test performance.
LIMITATIONS
1. The Multi-Drug One Step Screen Test Panel (Urine) provides only a preliminary analytical result. A more specic
chemical method must be used to obtain a conrmed result. Gas chromatography/mass spectrometry (GC/MS) is the
preferred conrmatory method.

2. It is possible 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.
4. A positive result indicates presence of the drug or its metabolites but does not indicate level of intoxication, administration
route or concentration in urine.
5. A negative result may not necessarily indicate drug-free urine. Negative results can be obtained when drug is present
but below the cut-o level of the test.
6. The test does not distinguish between drugs of abuse and certain medications.
7. A positive result might be obtained from certain foods or food supplements.
S.V.T. ADULTERATION LIMITATIONS
1. The adulteration tests included with this product are meant to aid in the determination of abnormal specimens. While
comprehensive, these tests are not meant to be an “all-inclusive” representation of possible adulterants.
2. Oxidants/PCC: Normal human urine should not contain oxidants or PCC. The presence of high levels of antioxidants
in the specimen, such as ascorbic acid, may result in false negative results for the oxidants/PCC pad.
3. Specic Gravity: Elevated levels of protein in urine may cause abnormally high specic gravity values.
4. Nitrite: Nitrite is not a normal component of human urine. However, nitrite found in urine may indicate urinary tract
infections or bacterial infections. Nitrite levels of > 20 mg/dL may produce false positive glutaraldehyde results.
5. Glutaraldehyde: Is not normally found in urine. However certain metabolic abnormalities such as ketoacidosis (fasting,
uncontrolled diabetes or high-protein diets) may interfere with the test results.
6. Creatinine: Normal creatinine levels are between 20 and 350 mg/dL. Under rare conditions, certain kidney diseases
may show dilute urine.
