The LAIHE MET Methamphetamine Urine Test Kit 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 300ng/mL or 500ng/mL or 1,000ng/mL, will not saturate the binding sites of 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 300ng/mL or 500ng/mL or 1,000ng/mL. because it will saturate all the binding sites of anti-Methamphetamine antibodies.
3. Specimen Collection and Preparation
(1) 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 precipitates should be centrifuged, filtered, or allowed settle to obtain a clear supernatant for testing.
(2) Specimen Storage
Urine specimens may be stored at 2-8°C for up to 48 hours prior to assay. For prolonged storage, specimens may be frozen and stored below -20°C. Frozen specimens should be thawed and mixed before testing.
4. Effect of the Urinary pH
The pH of an aliquoted negative urine pool was adjusted to a pH range of 5 to 9 in 1 pH unit increments and spiked. The spiked, pH-adjusted urine was tested with the LAIHE MET Methamphetamine Urine Test Kit in duplicate. The results demonstrate that varying ranges of pH does not interfere with the performance of the test.
