Intended Use
The
InstaCheck® 2
Panel Drug Screening Test
is
a visual, qualitative immunoassay for the rapid detection of THC (marijuana) and
Methamphetamine (including Ecstasy*) in human urine within 4 (M-AMP) 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 Methamphetamine at 500 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. 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. REAGENTS AND MATERIALS SUPPLIED InstaCheck® 2 Panel Drug Screening Test card with two (2) separate test regions for the targeted drugs, Marijuana and Methamphetamine. Each test region contains:
Warnings
& Precautions
Testing
Procedure
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. Interpretation of Test Results
The InstaCheck 2 Panel THC/M-AMP Drug Screening Test card is available in packs of 3, 6, 12, 24 and 100 test packs. Each test pack comes with complete instructions and expiration dates are in excess of one year. Tests may be stored at room temperature, no refrigeration is required.
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.
