INTRODUCTION
The one step Cassette Style Drug test is a rapid test based on the
principle of immunoassay combined with conjugated colloid gold
technology. The tests are designed to obtain a visual , qualitative
result and are intended for professional use only . They are not
intented for quantitative results ,nor for over-the-counter
sale.
The Drug Test provides only preliminary analytical data , A more
specific ,alternative method is required to obtain a confirmed
analytical result .SAMHSA has established gas chromatography / mass
spectrometry (GC/MS) as the preferred confirmatory method. Clinical
considerations and professional judgment should be applied to any
drug of abuse test result ,particularly when preliminary positive
Results are indicated.
PRINCIPLE OF THE PROCEDURE
The Drug Test is a competitive ,IVD, immunochromatographic ,urinary
assay in which a chemically modified and bound drug conjugate
competes with urinary MED for limited ,specific drug antibody
binding sites. The one step Cassette Style Drug Test have five
strips ,Each test stip contain a sample reaction unit , a
pink-colored , antibody-colloidal gold conjugate unit pre-labeled
with specific antibody ,and a chromatographic membrane pre-coated
with drug conjugate in the device test region .
When free drug is absent from urine or at concentration lower than
the urinary detection cut-off level, the pink-colored
,antibody-colloidal gold conjugate is free to bind to the
immobilized drug conjugate pre-coated on the chromatographic
membrane test region .Consequently ,a pink-colored band will form
in the test region indicating a negative result .When drug is
present in urine at concentrations at or exceeding the detection
cut-off level, it will bind to limited epitopes on the
pink-colored, antibody-colloidal gold conjugate , completely
competing with drug conjugate in the test region .In such cases ,
no band forms in the test region ,indicating a positive result.
The one step Cassette Style Drug test also provide a built-in
process control . A pink-colored band should always appear in the
control region , regardless of the presence of any urinary MED .
This pink-colored control band verifies that :1) sufficient urine
volume was added, and 2) proper flow was obtained. If the control
band is missing , the test was not performed correctly or failed to
function correctly. In summary , negative urine will produce two
pink-colored bands, one in the control region and one in the test
region .Positive urine will produce one pink-colored band in the
control region only .
MATERIALS REQUIRED BUT NOT PROVIDED
1. Urine sample collection containers
2. Timer or clock
INTERPRETATION OF RESULTS
Negative: Two pink-colored bands appear, one in the control region
and one in the test region. A negative result indicates free drug
is absent from urine or at concentrations lower than the detection
cut-off level of the test.
Positive: One pink-colored band appears in the control region with
no apparent band appering in the test region. A positive result
indicates free
drug is present in urine at concentrations at or exceeding the
detection cut-off level of the test.
Invalid: No band appears in the control region, or a pink-colored
band appears in the test region only. An invalid test result may be
due to improper assay procedures or damage to the device. If
results are invalid, the assay is inconclusive and the specimen
should be re-tested using a new test device.
Note: The band intensity may be weaker or stronger than that of the
control band.
