The MET One Step Methamphetamine Test Device is a lateral flow chromatographic immunoassay for the
detection of Methamphetamines in human urine.
This assay provides only a preliminary analytical test result. A
more specific alternate chemical method must be used in order to
obtain a confirmed analytical result. Gas chromatography/mass
spectrometry (GC/MS) is the preferred confirmatory method. Clinical
consideration and professional judgment should be applied to any
drug of abuse test result, particularly when preliminary positive
results are used.
The MET One Step Methamphetamine Test Device is a rapid chromatographic immunoassay based on the
principle of competitive binding. Drugs which may be present in the
urine specimen compete against the drug conjugate for binding sites
on the antibody.
During testing, a urine specimen migrates upward by capillary
action. Methamphetamines, if present in the urine specimen below
1,000 ng/mL, will not saturate the binding sites of the antibody
coated particles in the test device. The antibody- coated particles
will then be captured by immobilized Methamphetamine conjugate and
a visible colored line will show up in the test line region. The
colored line will not form in the test line region if the
Methamphetamine level exceeds 1,000 ng/mL because it will saturate
all the binding sites of anti-Methamphetamine antibodies.
A drug-positive urine specimen will not generate a colored line in
the test line region because of drug competition, while a
drug-negative urine specimen or a specimen containing a drug
concentration less than the cut-off will generate a line in the
test line region.
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.
