Methionine test reagents, also known as methamphetamine urine test panels, methamphetamine test kits, methyl amphetamine test reagents / test strips, methyl amphetamine test kits (colloidal gold method). The test sample is human urine .

This product is used for qualitative screening of methamphetamine in human urine samples.

Clinical application: drug control system, detoxification center, military station screening, entry-exit quarantine, etc.

Methylamphetamine: Methamphetamine, also known as ephedrine, commonly known as "

1. Methylamphetamine rapid reagent strip: coated with anti-methamphetamine monoclonal antibody, goat anti-mouse IgG, and methylamphetamine-BSA. Single serving in aluminum foil bag.

2. Instructions for use.

This reagent strip is only for urine sample detection. It is recommended to use fresh urine without any special treatment. Urine samples can be stored refrigerated at 2-8 ° C for 2 days, and frozen at -20 ° C for an extended period of 1-2 months. Refrigerated samples should be equilibrated to room temperature before testing. Frozen samples must be completely dissolved and thoroughly mixed before testing, otherwise the test results may be affected.

1. Read the instruction manual carefully before testing.

2. Warm the reagent strips, samples, and standards to room temperature (about 25 ° C) before testing. Do not open the packaging bag until you are ready. Refrigerated reagent strip packaging bags should be kept at room temperature in advance before tearing to avoid moisture absorption of test strips.

3. Remove the reagent strip from the sealed bag and mark the patient or standard number on the reagent strip.

4. Insert the sample end of the reagent strip into the urine sample for 10-15 seconds, remove it and place it on the platform. Note that when the reagent strip is immersed in the urine sample, the liquid level cannot exceed the MAX line at the sample end. Use different reagent strips for each different sample and standard.

5. Read the results 3-5 minutes after dropping the sample. Do not read the results after 5 minutes.

Sensitivity

The minimum detectable amount of methamphetamine is 1000ng / ml, 1000ng / ml is positive, and <1000ng / ml is negative.

Specificity

Samples with concentrations higher than or equal to 100 g / ml ephedrine, ranitidine, and phenylephrine hydrochloride showed positive results.

The following drugs with a concentration of less than or equal to 100 g / ml:

Thebaine, dihydroatofi, papaverine, narcotine, pethidine, fentanyl, methadone, tramadol, dextropropoxyphen, naloxone, naltrexone, buprenorphine, dilute Promorphine, clonine, lofioxetine, scopolamine, Yi'an oral solution Zhengtongning tablets rehabilitation new capsules paracetamol aspirin ibuprofen amitriptyline imipramine chlorpromazine and promethazine water Zolam, alprazolam, phenobarbital, canopy, isopentabarbital, cocaine, heroin, codeine, cannabis, amphetamine, caffeine, afloxacin, norfloxacin, vanguard IV, berberine, lactam, procaine, lidocaine Non-amphetamine abuse drugs and normal urine such as propanolamine, phenacetin, painkillers, folcodine, monoacetylmorphine, dihydrocodeine, phenobarbital, ketamine, 10 g / ml 9THC Is negative. ^[1]

Negative: Two bands should be observed in the window. The presence of a test line (T line) indicates the absence of methamphetamine; the presence of a quality control line (C line) indicates that the kit system is working properly.

Positive: Only a color band appears on the quality control line (C line), and the absence of the detection line (T line) indicates the presence of methamphetamine in the sample.

Invalid: The quality control line (C line) does not appear. In any case, the C line should be formed, and the absence of the C line indicates that the test result is uncertain, and should be retried.

Note: A very light band on the test line (T line) indicates that the concentration of methamphetamine in urine is close to the detection threshold of the reagent, and a more accurate and specific method should be used to confirm it before reaching a positive conclusion.
