Diagnostic Kit for Met Test

Diagnostic Kit for Met Test (Colloidal Gold)
Intended Use:
The MET One Step Methamphetamine Test Cassette is a lateral flow chromatographic immunoassay for the qualitative detection of Methamphetamine in urine at the following cut-off concentrations of 1,000ng/ml.
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.
Summary:
Methamphetamine is an addictive stimulant drug that strongly activates certain systems in the brain. Methamphetamine is closely related chemically to amphetamine, but the central nervous system effects of Methamphetamine are greater. Methamphetamine is made in illegal laboratories and has a high potential for abuse and dependence. The drug can be taken orally, injected, or inhaled. Acute higher doses lead to enhanced stimulation of the central nervous system and induce euphoria, alertness, reduced appetite, and a sense of increased energy and power. Cardiovascular responses to Methamphetamine include increased blood pressure and cardiac arrhythmias. More acute responses produce anxiety, paranoia, hallucinations, psychotic behavior, and eventually, depression and exhaustion.
The effects of Methamphetamine generally last 2-4 hours and the drug has a half-life of 9-24 hours in the body. Methamphetamine is excreted in the urine primarily as amphetamine and oxidized and deaminated derivatives. However, 10-20% of Methamphetamine is excreted unchanged. Thus, the presence of the parent compound in the urine indicates Methamphetamine use. Methamphetamine is generally detectable in the urine for 3-5 days, depending on urine pH level.
The MET One Step Methamphetamine Test Cassette yields a positive result when the concentration of methamphetamine in urine exceeds 1,000ng/ml.
Warings and Precautions:
· For in vitro diagnostic use only.
· For healthcare professionals and professionals at point of care sites.
· Do not use after the expiration date.
· Please read all the information in this leaflet before performing the test.
· The test panel should remain in the sealed pouch until use.
· All specimens should be considered potentially hazardous and handled in the same manner as an infectious agent.
· The used test panel should be discarded according to federal, state and local regulations.
Specimens:
· 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 to settle to obtain a clear supernatant for testing.
· Urine specimens may be stored at 2-8°C for up to 48 hours prior to testing. For prolonged storage, specimens may be frozen and stored below -20°C. Frozen specimens should be thawed and mixed well before testing.
Test Procedure:
Allow the test and urine samples to equilibrate to room temperature (15-30℃or 59-86℉) prior to testing.
1. Remove the test cassette from the sealed pouch.
2. Hold the dropper vertically and transfer 3 full drops (approx. 100ml) of urine to the specimen well of the test cassette, and then begin timing. See the illustration below.
3. Wait for colored lines to appear. Interpret the test results at 3-5 minutes. Do not read results after 10 minutes.
Interpretation of Results:
Negative: *Two lines appear. One red line should be in the control region (C), and another apparent red or pink line adjacent should be in the test region (T). This negative result indicates that the drug concentration is below the detectable level.
*NOTE:The shade of red in the test line region (T) will vary, but it should be considered negative whenever there is even a faint pink line.
Positive: One red line appears in the control region (C). No line appears in the test region (T). This positive result indicates that the drug concentration is above the detectable level.
Result Interpretation:
Negative:only one color band appears on the control region,No apparent band on the test region .There is no pregnancy
Positive:Distinct color bands appears on the control and test regions,Both test line and control line indicate that you are pregnant.
Invalid:No visible bang at all.Repeat test with a new test kit.
