A urine test for drugs is the most accurate method that makes it possible to determine whether a person has taken illegal drugs. He will be able to detect the fact of drug use even a few weeks after they were taken. Of course, a lot depends on the type of drug. The heavier they are, the longer they are excreted from the body.
Modern laboratory tests make it possible to determine the presence of even a minimal amount of narcotic substances in urine and blood. You can learn about how to pass a drug test in the urine after a detailed study of the mechanism of most tests, as well as how to pass them.
Detection of drugs in the body
Drugs, depending on the species, have different effects on the human body. That is why for each individual case a special type of analysis is selected . For example, to detect marijuana in a person’s blood, you will have to wait an average of 20 days. This period depends on how quickly the substance dissolved in the body, as well as on the time that was used to accumulate the drug in the internal organs. You can take a drug test in Penza or any other city in Russia without any doctor's referral. You just need to choose a good laboratory and pass some urine for analysis.
Due to the long absorption, particles of narcotic substances move into the circulatory system after a certain period of time. It may take up to 3 weeks to study the composition of the blood to make sure that the person has used hard drugs. Fortunately, you can take an express drug test, which determines their presence in the body.
Urinalysis for drugs
This rapid method for detecting narcotic substances in urine is the most popular in most laboratories. Having chosen this type of analysis, it is worth remembering that its result depends on how quickly it was carried out. If you notice the strange behavior of a friend or relative, you must immediately go with him for an examination. The faster urine is given after taking the drug, the more effective the result will be. You can take a drug test in Moscow in any laboratory that provides tests.
To collect urine use a special container that is issued directly in the laboratory. If a loved one does not want to go for examination, you can buy disposable containers in a pharmacy. The container must be completely dry. Do not dilute urine with water or any other liquid.
Test Storage Rules
After urine collection, the container is closed with a lid and moved to the refrigerator. This is done before when you need to take a drug test in a few days. The temperature in the refrigerator should not be below zero. In a dark and cold place, the collected urine can be stored for up to 3 days. However, she will not lose her elements necessary for detecting the presence of drugs. When the time comes for the analysis, the container with urine is taken to the laboratory. Specialists label containers and immediately give them for research. You can take a drug test in St. Petersburg almost any day. Most laboratories are open around the clock. Therefore, even with a busy work schedule, you can easily pass all the necessary analyzes.
When drug testing is required
They are sent to take tests for various indications. They mainly relate to appointments for serious and responsible jobs. When collecting documents for employment, each company will require a medical certificate containing information about various types of tests, including drugs. Particular attention is always paid to people who are employed in the following positions:
- Pilot, air traffic controller.
- Serving in the army and military forces.
- Police officers.
- Drivers of freight and public transport categories.
- Space station workers.
- Doctors
All law-abiding citizens of the country should know how to pass a drug test. According to the law, all students and schoolchildren are required to undergo an annual medical examination, which includes the most necessary examinations of the body, as well as a drug test. Compulsory research is carried out by people who have got into accidents.
Immunochromatographic analysis
When thinking about how to pass a drug test, you need to remember that there are several ways to do this. Immunochromatographic analysis is one of the most popular types of detection of narcotic substances in urine. This laboratory method consists of the following steps:
- Urine is sucked in with a special pipette and passed through an absorbent device. If there is a drug in urine, the device begins to react and forms an antigen-antibody.
- Then the urine is transferred to the pink strip, indicating that the analysis was carried out in accordance with the rules and has a reliable result.
If in the near future a person has not taken drugs, the analysis will show a negative result. Then two strips will be reflected on the device. However, such a result is quite possible with small doses of drug use. A negative result may appear if their concentration is insufficient. Of the advantages of this method of analysis, we can note its efficiency. One hour after the delivery of urine from the laboratory, a verdict can be obtained. If the result is positive, you should immediately contact a narcologist.
Chemical toxicological analyzes
Of these, the most common can be distinguished:
- An analysis of PFIA urine, which is done to identify a specific group of drugs: cocaine, amphetamines, methadones and all their varieties.
- A urinalysis called an ELISA. It is carried out to detect drugs of several groups at once.
- Chromatography-mass spectrometry. This analysis is the most common in most laboratories.
- Gas-liquid chromatography. This method is used to detect the presence in the blood of not only drugs, but also alcohol.
All of the above types of analyzes are the most accurate and highly sensitive. They are used during a medical commission when applying for a job, at an institute, or before serving in a military unit.
Analysis validity
If drugs are found in the blood, saliva or urine of a person, they are referred to a narcologist for a consultation. The doctor issues a certificate that will affect his further employment or studies. The duration of this document depends on many factors. Among them, the most significant role is played by the following:
- The type of drug found in the body.
- The amount of their use.
- The method used in the diagnosis.
Before you pass a drug test, it is worth remembering that the minimum validity of the certificate is 1 month. If, during a second test, drugs were again detected in the human body, the duration of such a document may exceed a period of 1 year.
