Rapid drug tests
Today, almost every day there are new varieties of drugs, so the number of consumers is growing steadily.

In addition, it is not a problem and where to buy such a test — today they are sold in almost any pharmacy.

Such 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 in the form of a cassette. When using this test, you should drop three drops of bioobrazca in a special window.

Rapid tests are highly sensitive, they are able to detect the remains of opium drugs within 5 days of use, and cannabioid like hashish or marijuana – within 14 days, even if the reception was a single. You can take such a test at home, and the sale of Express tests are engaged in pharmacies.

Views
Drug tests are of several types:

Test strips for the determination of narcotic substances in urine – these tests are strips impregnated with indicator substances, through which the presence of a certain drug is detected. Such a set of flat can be used even in cases when the drugs are unknown. Such a study can be carried out at home.
Rapid drug tests help to answer the question where to take the test. They are convenient to use in schools and other similar institutions. Similar tests are used to examine urine. The whole procedure takes no more than 10 minutes, and special equipment or inventory is not required, so the study can be carried out at home.
Tests from the series Narcoscreen. Able to simultaneously determine the presence of biomaterial in a variety of drugs (5 or 10 species). As the test material can be used saliva or urine test. In the study of urine, the test is immersed in a container with a liquid, and when checking the saliva on the test, there is a special panel that is applied to the saliva. In the set of tests are usually applied to additional attributes such as a kind of pipette to collect saliva or a Cup for urine.

For what types of drugs

Any drug in the body is converted into a certain metabolite, which is not so much. Thus, opiates, codeine, heroin or morphine are transformed into morphine, the presence of which in the urine determines the MultiTest drug. And it can be found not only in urine, but also in saliva, hand washes, clothes and other research materials.

Modern rapid tests are able to detect 2-10 varieties of various drugs such as:

Heroin, morphine;
Marijuanas;
Amphetamine and methamphetamine;
Barbiturates';
Cocaine's;
Methadone;
Ecstasy or MDMA;
Phencyclidine;
Benzodiazepine;
Antidepressant drugs;
Alcohol and nicotine.
In the method for determining
Modern drug tests, suitable for use in the home, can detect drugs on the study of saliva or urine. In terms of drug addiction or substance abuse clinic spectrum of the investigated materials is much larger. Confirm or deny the fact of consumption of drugs in such institutions can be saliva, urine, blood, hair, from the surface of clothing or hands, etc.

Unfortunately, the drug market today is flooded with synthetic novelties like Smoking blends, spices, mixes, etc. This is a whole group of psychoactive, addictive substances.

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 a narcologist can help.

Principle of operation
Each drug test has a control area that displays the results of the study. The principle of operation of such multitests is simple. If the biomaterial contains narcotic compounds, the specific antibodies, which impregnated the test strip, react to the products of drug metabolism. As a result, one strip appears on the control area.

If the subjects did not use drugs, the result will be negative, and the control area will show two red lines. Most parents have a positive result causes extreme bewilderment and even indignation, because in recent days their child behaved quite adequately. This is due to the long withdrawal of narcotic products like marijuana or cocaine, which can last up to 2 weeks.

Rules and requirements
To use the test analyzer correctly, you need to follow a few specific rules:

Biomaterial should be collected only in clean dishes made of glass or plastic like a glass.
Urine or saliva shall be collected under such conditions that the test subject cannot dilute or replace the sample.
If the urine is collected, and there is no MultiTest, the sample can be kept in the refrigerator for some time. When the test is available, the urine is left to warm up to room temperature, only then the study is carried out.
In the course of the study revealed the fact of drug use no later than 2-3 days from the date of their use. In the case of cannabis drugs, methadone, cocaine or benzodiazepines, the availability of drugs is determined within two weeks of the time of anesthesia.
Both the biomaterial and the test should be at room temperature so that the results are as reliable as possible.
The test strip is dipped into the biomaterial to the limiting line for 0.5-1 minute, then put it on a dry plane. The results are evaluated after a 5-10-minute period of time.
As a result, the analysis is deciphered in 2 strips as negative, i.e. drugs were not used by the subjects.
The result in 1 striped confirms that took place the use of narcotic substances. With a positive result, urine samples should be stored for a more complete analysis.
If no lines are displayed on the test strip, the study is considered to be erroneous and requires repetition by another MultiTest.
