The
InstaCheck® 2
Panel Drug Screening Test
is
a visual, qualitative immunoassay for the rapid detection of THC (marijuana) and
Cocaine in human urine within 3 (COC) to 6 (THC) minutes at an accuracy level
of 98% when used as instructed.
The cutoff concentrations for this test are THC metabolite (THCA) at 50
ng/mL and Cocaine metabolite (Benzoylecgonine) at 300 ng/ml. The sensitivity
levels of this test are in conformance with the testing guidelines for this type
of immunoassay established by the National Institute on Drug Abuse (NIDA) and
the U.S. Department of Health and Human Services.
Summary
and Explanation of the Test
D9-Tetrahydrocannabinol (THC) is generally accepted to be the principle active component in marijuana and hashish, although other Cannabinoids are likely to contribute to their physiological activity also. THC is rapidly absorbed by inhalation or by the gastrointestinal tract, and is almost completely metabolized. Its predominant metabolite, 11-Nor-D9-THC-9-carboxylic Acid, or THCA, is found in the plasma, feces and urine along with other compounds. Very low concentrations of THC may be detected in urine during the initial several hours, but THCA persists in urine at a detectable concentration for many days after smoking or other ingestion.
Cocaine (COC) is an alkaloid present in coca leaves (Erythyroxine coca) whose pharmacological properties include alertness, wakefulness, increased energy and an overall feeling of euphoria. Cocaine has been used medicinally as a local anesthetic, however, its addictive properties have minimized its modern value as an anesthetic. Elimination of cocaine is predominantly controlled by its biotransformation. It is almost completely metabolized to Benzoylecgonine. Very low concentrations of Cocaine may be detected in urine during the initial several hours, but Benzoylecgonine persists in urine at detectable concentrations for approximately 48 hours.
Urine-based
screening tests for drugs of abuse range from complex analytical procedures to
simple immunoassay tests. The sensitivity and rapidity of the InstaCheck® 2 Panel Drug Screening Test
has made this type of immunoassay the most accepted method of preliminary
screening for drugs of abuse in urine.
Principles
of the Procedure
The InstaCheck® 2 Panel Drug Screening Test is
a competitive immunoassay that is used to screen for the presence of drugs of
abuse in urine. It
is a chromatographic absorbent device in which drugs or drug metabolites in a
sample compete with drug / protein conjugate immobilized on a porous membrane
for a limited number of antibody /dye conjugate binding sites.
The test device employs a unique combination of monoclonal and polyclonal
antibodies to selectively identify drugs of abuse in urine with a high degree of
confidence. In
the procedure, the absorbent end of the test device is inserted into the urine
sample. The urine is
absorbed into the device by capillary action, mixes with the antibody/dye
conjugate, and flows across the pre-coated membrane.
When sample drug levels are below the target cutoff
sensitivity of the test, antibody/dye conjugate binds to the drug/protein conjugate immobilized in the Test Region (T) of the device. This produces a colored Test Band that, regardless of intensity, indicates a negative result.
When sample drug levels are at or above the target cutoff, the free drug in the sample binds to the antibody/ dye conjugate, preventing the antibody/dye conjugate from binding to the drug/protein conjugate immobilized in the Test Region (T) of the device. This prevents the development of a distinct colored band, indicating a positive sample.
In either case, a colored Control Band is produced in the Control Region (C). This band serves as a built-in quality control device that demonstrates antibody recognition and reactivity as well as confirmation that the test is complete.
Reagents & Materials Supplied
InstaCheck® 2
Panel Drug Screening Test card with two (2) separate test regions for
the targeted drugs, Marijuana and Cocaine. Each
test region contains:
-
Monoclonal anti-drug antibody/colloidal gold conjugate in a protein matrix containing 0.1% sodium azide coated in the sample path.
-
Drug derivative/protein conjugate immobilized as a line in the test region.
-
Goat anti-mouse antibody immobilized as a line in the control region.
-
Sample
transfer pipette, complete
use instructions and technical background information.
Warnings
& Precautions
Testing
Procedure
-
Read
the enclosed instruction manual completely.
-
Do
not open the sealed test pouch until just prior to sample testing.
-
Collect
a fresh urine sample in a clean container preferably glass.
-
Check
the expiration date and remove the test device from the sealed pouch. Do not
use the test past its expiration date.
-
Remove
the protective cap from the test device to expose the absorbent wicks.
- Immerse
the wicks into the sample, making
sure that the urine level does not come in contact with the test device.
-
Observe
sample lateral flow or migration across the test panels (15-20 seconds).
-
Read
results within 3 to 7 minutes after sample migration. (The two test panels
will not fully develop at the same time) Do not read result after 8 minutes.
If the drug test is left standing for longer than 8 minutes, the intensity
of the colored lines may change or for technical reasons, a faint line may
appear that should not be interpreted.

The above
result indicates a negative test result for both Marijuana and Cocaine.
The presence of a test line, no matter how faint, next to the labeled
drug test area is a negative result. Note that the color or intensity of
the lines may differ. This is normal. |
The above
result indicates a positive test for Marijuana and a negative test for
Cocaine. The absence of a line in the THC test area is a positive test
result for that drug. |
The above
result indicates a positive test for Cocaine and a negative test for
Marijuana. The absence of a line in the COC test area is a positive test
result for that drug. |
The absence
or lack of development of a control line is an invalid test result
regardless of other test results. No interpretation of test results
should be made. |

NOTE: This test 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) has been established as the preferred confirmatory method by the Substance Abuse Mental Health Services Administration (SAMHSA). Clinical consideration and professional judgment should be applied to any drug of abuse test result, particularly when preliminary positive results are indicated.
If confirmation of positive scans is required, we suggest the QuickScreen
Pro At Home kit with Laboratory Confirmation of positive results.
