(MET) hair drug trace rapid test kit
Introduction
MET, commonly known as "crystal", for the pure white crystal.Its molecular formula is C10H15N, and its structural formula is 
.After taking will lead to MET central nervous system excitement, abnormal euphoria, sensitivity increased, and consciously energetic, heartbeat and breathing faster, long-term or a large number of easy to produce tolerance and dependence.
Intended Use
A rapid test for the quantitative detection of drugs in human hair.
Hair analysis has become an optional and complementary means of drug abuse detection. Generally, drugs in urine, blood and saliva are basically metabolized clean after 7 days of smoking. Compared with body fluid analysis, hair has more advantages.Longer detection window (from 1 week to several months);Hair analysis provides cumulative images of long-term exposure.
Drugs are metabolized under the action of blood lipid enzyme after entering the human body, and further metabolized after entering the liver. A considerable amount of drugs and metabolites enter the hair, which is mostly combined with melanin and other substances in the pulp cavity of the hair.
The hair growth rate is about 1 cm per month, and the drug combined with hair will grow forward with hair instead of spreading along the hair shaft. Hair is marked as roots, ends and cut into several sections, and each section was measured separately. According to the measurement of result and the growth rate of hair, the time of drug absorption and the amount of drug use could be speculated roughly. This is the blood, urine toxicity analysis which are currently unable to do, and that is one of the reasons for the preference of toxicological analysis workers.
The use of this product needs to match with Immunofluorescence quantitative analyzer manufactured by Hangzhou Laihe Biotech Co., Ltd. (Model：FA-LF100C).
Features
1 This product uses the principle of immunochromatography to quickly detect KET content.
2 Using high-purity raw materials and high-quality materials, it shows extremely high sensitivity and specificity.
3.Easy to operate
Operation
1. Preparation: turn on the hair drug trace analyzer of Hangzhou Laihe Biotech Co., Ltd.
2. Before testing, restored the test kit, hair lysate buffer and the ID card to room temperature (15-30 C). Suggest opening them after restoring to room temperature (15-30°C)
3.Read the ID card: confirm whether the ID card is matched with the batch number of the test kit, insert the ID card, and click on the confirmation button on the analyzer’s screen to read the ID card, then the kit can be detected.
4. Select "hair" in the sample type on the instrument’s screen.
5. Cut 5mg hair (about 10*10cm length hair) that to be detected into 1-2mm section with the scissors, collected by a weighing paper, then shake it into the centrifuge tube containing the hair lysate buffer, cover the centrifuge tube cap, shake and mix for 1 minutes. Use the dropper to absorb the supernatant of hair lysate buffer and added two drops into the sample hole of the test kit’s plate.
6. Reading: the test kits react time is about 3 minutes after adding the sample, and then insert the test kit into the instrument immediately after the reaction ends. Click the "test" button. The system will automatically read theTest kit and give the test results. After 5 minutes, the test result is invalid.
Interpretation of Results
When the detection result of MET< 0.1ng/mg, it is judged to be negative.
When the detection result of MET≥ 0.1ng/mg, it is judged to be positive.
