Test Features:
The iScreen drug Test is
an on-site (rapid) urine
test offering low cost and
convenient collection. The
iScreen is used by removing
the end cap and inserting
the detection device into
the collection cup. Once
the detection device is
inserted, the tests will
begin to run. The test results
will be visible in a few
minutes and if no drugs
are found the corresponding
panel will develop a red
line below the Control Line.
iScreen Urine drug test
kits are the least expensive
and most flexible (meaning
it is possible to test
for many different drugs
in different combinations)
in testing drugs. Results
of an iScreen urine
drug test detect the
presence or absence
of specific drugs in
the urine. A positive
urine test result does
not necessarily mean
that the donor was under
the influence of drugs
at the time of the test.
iScreen can be
defined as a rapid,
one step screening test
for the simultaneous,
qualitative detection
of multiple drugs and
drug metabolites in
human urine.
iScreen Drug Test 4 panel
urine drug test 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 specific
antibody. During testing,
a urine specimen migrates
upward by capillary action.
A drug, if present in the
urine specimen below its
cut-off concentration, will
not saturate the binding
sites of its specific antibody.
The antibody will then react
with the drug-protein conjugate
and a visible colored line
will show up in the test
line region of the specific
drug strip. The presence
of drug above the cut-off
concentration will saturate
all the binding sites of
the antibody. Therefore,
the colored line will not
form in the test line region.
A drug-positive urine specimen
will not generate a colored
line in the specific test
line region of the strip
because of drug competition,
while a drug-negative urine
specimen will generate a
line in the test line region
because of the absence of
drug competition. 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.
