Too many people today are dependent on various drugs, so rapid tests for the definition of drugs have become widespread. With the help of the present invention, it is possible to check at home whether a person has taken any drug. There are several similar tests, each has its own peculiarities, so it is worth considering this issue in more detail.

Express tests for drugs

Today, almost all new varieties of narcotic substances appear almost every day, therefore the number of consumers is steadily growing. Drug testing can help determine whether a person is using drugs or your suspicions are unfounded, and suspicious signs of drug dependence are evidence of a disease. In addition, there is no problem and where to buy such a test - today they are sold in almost any pharmacy.

Similar tests look like a paper strip on which there is a layer like a blotter, impregnated with various compositions of protein and chemical origin. When urine or saliva permeates this layer, it, in the presence of a narcotic substance, reacts with impregnation. As a result, a bright strip appears on the test. There are tests and in the form of a cassette. When using this test, you should drop three drops of bio-sample into a special window.

Types of

There are several types of drug tests:

• Urine test strips - these tests are strips impregnated with indicator substances, due to which a certain drug is detected. Such a set of flat can be used even in cases when the type of narcotic substance is unknown. Such a study can be done in a home environment.
• Express tests for drugs help answer the question where to take the test. They are convenient for use in schools and other similar institutions. Similar tests are used to study urine. The whole procedure takes no more than 10 minutes, and special equipment or equipment is not required, so the study can be conducted at home.
• Tests from the Narcoscreen series. Are able to simultaneously determine the presence in the biomaterial of several varieties of narcotic substances( for 5 or 10 species).As a test material, saliva or urine test can be used. When the urine is tested, the test is immersed in a container with a liquid, and when testing saliva on the test, there is a special panel that is applied by saliva. In the test suite, additional attributes are usually applied, such as a kind of pipette to collect saliva or a cup for urine.

Narcotic Drug Narcotics

For which types of drugs

Any drug in the body is converted into a certain metabolite, which is not so much. So, opiates, codeine, heroin or morphine are transformed into morphine, whose presence in the urine is determined by the multitest drug. And it can be found not only in the composition of urine, but also in saliva, washings of hands, clothing and other research materials.

Modern rapid tests can detect 2-10 species of various drugs like:

• Heroin, morphine;
• Marijuana;
• Amphetamine and methamphetamine;
• Barbiturates;
• Cocaine;
• Methadone;
• Ecstasy or MDMA;
• Fenzyclidine;
• Benzodiazepine;
• Antidepressant drugs;
• Alcohol and nicotine.

By the method of determining

Modern tests for drugs suitable for home use can detect narcotic substances for the study of saliva or urine. In the conditions of a narcological dispensary or narcological clinic, the spectrum of the materials under study is much broader. To confirm or deny the fact of consumption of narcotic substances in such establishments it is possible on saliva, urine, blood, hair, from the surface of clothing or hands, etc.

The problem of test studies is the lack of reliability in relation to such drugs, so it is difficult to reliably determine the use of such substances. In such a situation, only the narcologist can help.

Principle of operation of

In each drug test, there is a control area on which the results of the study are displayed. The principle of operation of such multivers is simple. If there are narcotic compounds in the biomaterial, then the specific antibodies that impregnate the test strip react to the products of the drug metabolism. As a result, one strip appears on the control area.

If the drugs were not used for the test subjects, the result will be negative, and two red lines will appear on the control area. At the majority of parents the positive result causes extreme bewilderment and even indignation, after all last days their child behaved quite adequately. This is due to the long-term withdrawal of narcotic products such as marijuana or cocaine, which can last up to 2 weeks.

Scheme for determining the results

Rules and requirements

For the correct use of the test analyzer, several rules must be observed:

1. The biomaterial must be collected only in clean glass or plastic utensils such as a glass.
2. The collection of urine or saliva should be carried out under such conditions that the subject can not dilute or replace the sample.
3. If the urine is collected and there is no multitest, the sample can be held in the refrigerator for a while. When the test is available, the urine is left to warm up to room temperature, only then do the research.
4. In the process of investigation, the fact of using narcotic substances is revealed not later than 2-3 days from the moment of their use. In the case of cannabis drugs, methadone, cocaine or benzodiazepines, the presence of drugs is determined within two weeks from the time of narcotization.
5. Both the biomaterial and the test should be at room temperature, so that the results are as reliable as possible.
6. The test strip is dipped into the biomaterial to the limit line for 0.5-1 minutes, then put it on a dry plane. The results are evaluated after a 5-10 minute period of time.
7. As a result, in 2 strips the analysis is deciphered, as negative, ie, drugs were not used for the test subjects.
8. The result in 1 bar confirms that there was a drug use. With a positive result, urine samples should be retained for a more complete analysis.
9. If no lines are displayed on the test strip, then the study is considered erroneous and requires repetition by another multitextile.
