Manufacturer of MOR morphine gold standard rapid detection kit Shanghai Kaichuang biology

Kaichuang morphine detection kit applies gold standard technology to quickly detect morphine in human urine in one step
It can directly observe the results with the naked eye, and the detection threshold is 300ng / ml
This product is for professional use 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 Opioids such as heroin, morphine and codeine are extracted from the resin of poppy fruit
Because heroin and codeine are rapidly metabolized into morphine and glucose morphine in the body
Therefore, the presence of morphine and exceeding the threshold indicates that the patient has taken more than a dose of heroin, morphine or codeine
There are many urine screening methods for drug abuse, including simple immune detection and complex chemical analysis methods
Colloidal gold immunochromatography has become a widely used method in drug abuse urine screening because of its rapidity, high sensitivity and high specificity Kaichuang morphine detection kit uses immune competitive inhibition method to detect the presence of morphine in urine, that is, protein labeled * (* carrier) competes with * in urine for limited antibody binding position
A test strip is placed in the test card, the test line area of the test strip is coated with morphine carrier conjugate, and a dried morphine antibody colloidal gold paper is placed at one end of the test 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 morphine 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 * colloidal gold carrier for limited antibody binding position in the detection area
When * concentration reaches a certain amount, it will occupy all antibody binding sites, thus preventing the binding between * carrier and its antibody colloidal gold
In this way, the wireless bar in the detection area appears, indicating that the result is positive
The quality control area on the test strip is coated with specific antigen antibody to indicate that the reaction system of the kit works normally
This 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 Mor (morphine) gold standard rapid detection kit products www
