Manufacturer of MDMA gold standard rapid detection kit Shanghai Kaichuang biology

MDMA ecstasy detection kit applies gold standard technology to legally detect the presence of MDMA (methylene dioxymethamphetamine) and its metabolites in human urine in one step, which is used for specific auxiliary diagnosis of whether patients have taken & ldquo; Ecstasy & rdquo;, The threshold is 500ng / ml
The kit is simple and fast to operate, and provides visible and qualitative results for professionals only
This product only provides preliminary test results, and untrained non professionals may misjudge the results
The determination of the results must be obtained by accurate chemical analysis
The preferred confirmation method recommended by the National Institute of drug abuse is gas chromatography-mass spectrometry (GC / MS)
When the initial screening result is positive, it must be determined by this method and judged by professional doctors in combination with clinical symptoms MDMA, full name: 3,4-methylenedioxy-n-methylamphetamine, also known as ectasy, Chinese Name: methylene dioxymethamphetamine, commonly known as & ldquo; Ecstasy & rdquo;, The composition of ecstasy is very complex, and MDMA is its main component
MDMA, as a precursor of chemical drugs, was synthesized and patented by pharmaceutical manufacturers in the early 20th century
It is similar to methamphetamine in chemical structure and has similar central nervous stimulation, but its hallucinogenic effect is much greater than that of methamphetamine
It was not until the 1980s that MDMA was considered an illegal drug
In 1985, the United States * administration classified this drug as a class I restricted drug (that is, a drug with high addiction and can not be used as a common drug)
Although the drug has been included in the first category of controlled drugs, the illegal use rate of MDMA is very high, so an accurate and specific method is needed to detect and monitor it
MDMA is usually made into tablets or capsules at a dose of 80-150mg
After oral administration, the drug reaction can last for 3-6 hours
Like methamphetamine, it can cause a series of symptoms such as elevated blood pressure, elevated body temperature, confusion of thinking, anxiety, paranoid sleep disorder and so on
It has been reported that its symptoms can last for weeks
After taking MDMA, 65% were excreted from urine in the form of plasma, and nearly 7% were excreted from urine in the form of demethylation to produce methylene amphetamine (MDA)
Other metabolic forms include monohydroxylation or double hydroxylation
In general, MDMA can be detected in urine within about 3 days after taking it The MDMA detection kit uses the immune competitive inhibition method to detect the presence of MDMA in urine, that is, the * (* carrier) labeled by protein has limited competition with the * antibody binding sites in urine
A test strip is placed in the kit, and the MDMA carrier conjugate is coated on the test line area of the test strip
A dried MDMA antibody colloidal gold paper is placed at one end of the detection area
If there is no * in the urine, the * antibody colloidal gold will run on the membrane with the sample solution to the detection line and combine with the MDMA carrier conjugate to show a line visible to the naked eye, which is a negative result
If the urine contains * or * metabolites, they will compete with the * carrier for limited antibody binding sites
When the * concentration in the sample reaches a certain amount, it will occupy all antibody binding sites on the antibody colloidal gold, thus preventing the * carrier on the test strip detection area from binding to the antibody colloidal gold
In this way, the wireless strip in the detection area appears, indicating that the result is positive
The quality control area on the test strip is coated with specific antibodies to indicate whether the reagent kit reaction system works normally
The quality control line is independent of the presence of * or * metabolites
The appearance of the color band in the quality control area shows that: ① the amount of sample added is sufficient; ② the sample runs normally on the paper strip MDMA gold standard rapid detection kit products www
