Methamphetamine Met Drug Screening Test

size:

strip: 2.5mm,3.0mm,3.5mm,4.0mm

cassette: 3.0mm,4.0mm

PRINCIPLE:

The MET One Step Methamphetamine Test Strip (Urine) is an 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. Methamphetamine, if present in the urine specimen below 1,000 ng/mL, will not saturate the binding sites of antibody coated particles in the test strip. 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, 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.

Specimen Collection:

Urine Assay:

The urine specimen must be collected in a clean and dry container.Urine collected at any time of the day may be used.Urine specimens exhibiting visible particles should be centrifuged, filtered, or allowed to settle obtain a clear specimenfor testing.

Specimen Storage:

Urine specimen may be stored at 2-8°c for up to 48 hours prior to assay. For long-term storage, specimens may be frozen and stored below -20°c. Frozen specimens should be thawed and mixed before testing.
