Ethyl Glucuronide ETG Urine Strip Drug of Abuse Rapid Test Kit
Ethyl Glucuronide (ETG) Rapid Test is a rapid, screening test for
the qualitative detection of Ethyl Glucuronide (ETG) and
metabolites in human urine at specified cut off levels.
For professional use only.
For in vitro diagnostic use only.
【INTENDED USE OF ETG URINE TEST】
Ethyl Glucuronide (ETG) Rapid Test is an immuno-chromatographic
assay for the qualitative determination of the presence of Ethyl
Glucuronide (ETG). This assay provides only a preliminary analytical test result. Gas
Chromatography/Mass spectrometry (GC/MS) is the preferred
confirmatory method. Clinical consideration and professional
judgment should be applied to Ethyl Glucuronide (ETG) of abuse test
result, particularly when preliminary positive results are
indicated.
【SUMMARY OF ETG URINE TEST】
Ethyl Glucuronide (EtG) is a direct metabolite of alcohol. Presence
in urine may be used to detect recent alcohol intake, even after
alcohol is no longer measurable. Traditional laboratory methods
detect the actual alcohol in the body, which reflects current
intake within the past few hours (depending on how
much was consumed). The presence of EtG in urine is a definitive
indicator that it can be detected in the urine for 3 to 4 days
after drinking alcohol, even alcohol
is eliminated from the body. Therefore, EtG is a more accurate
indicator of the recent intake of alcohol than measuring for the
presence of alcohol itself. The EtG test can aid in the diagnosis
of drunk driving and alcoholism, which has important significance
in the forensic identification and medical examination
【PRINCIPLE OF ETG URINE TEST】
Ethyl Glucuronide (ETG) Rapid Test is a competitive immunoassay
that is used to screen for the presence of Ethyl Glucuronide (ETG)
and metabolites in urine. It is chromatographic absorbent device in
which, drugs within a urine sample, competitively combined to a
limited number of drug monoclonal antibody (mouse) conjugate
binding sites.
When the test is activated, the urine is absorbed into test by
capillary action, mixes with the respective drug monoclonal
antibody conjugate, and flows across a pre-coated membrane. When
drug within the urine sample is below the detection level of the
test, respective drug monoclonal antibody conjugate binds to the
respective drug-protein conjugate immobilized in the Test Region
(T) of the test . This produces a colored Test line in the Test
Region (T) of the test, which, regardless of its intensity,
indicates a negative test result.
When sample drug levels are at or above the detection level of the
test, the free drug in the sample binds to the respective drug
monoclonal antibody conjugate, preventing the respective drug
monoclonal antibody conjugate from binding to the respective
drug-protein conjugate immobilized in the Test Region (T) of the
device.
This prevents the development of a distinct colored band in the
test region, indicating a preliminary positive result.
To serve as a procedure control, a colored line will appear at the
Control Region (C) of test, if the test has been performed
properly.
【OPERATION】
Test must be in room temperature (15ºC to 30ºC)
1. Donor collects urine specimen in a urine cup.
2. Open the sealed pouch by tearing along the notch. Remove the
test from the pouch and place it on a level surface.
3. Hold the sample dropper vertically, and add exactly three drops
of the urine specimen into the sample well.
4. The result should be read at 5 minutes. Do not interpret the result after 10 minutes. See the
illustration below.
【INTERPRETATION OF RESULTS】
Positive (+): Only one colored band appears in the control region (C).
Negative (-): Two colored bands appear on the membrane.
Invalid: Control band fails to appear.
【STORAGE AND STABILITY】
- The kit should be stored at 2-30°C until the expiry date printed on
the sealed pouch.
- The test must remain in the sealed pouch until use.
- Keep away from direct sunlight, moisture and heat.
- Do not freeze.
- Care should be taken to protect the components of the kit from
contamination. Do not use if there is evidence of microbial
contamination or precipitation. Biological contamination of
dispensing equipment, containers or reagents can lead to false
results.
