Alcohol test

Alcoholic beverages have a negative effect on the human body. First of all, perception is disturbed and reactions slow down. Such phenomena can have an extremely negative impact on the normal life of a person. For this reason, it is important to always control the amount of alcohol and not abuse it. Alcohol can be detected in the blood as early as 10-15 minutes after ingestion. Then it dissipates throughout the body and after about 25 minutes it can be found in saliva or air that is exhaled. Also, the presence of alcohol can be detected in the urine, since the kidneys are directly involved in the processing of toxins. Therefore, the analysis of urine, saliva and air that is exhaled allows you to determine whether there is alcohol in the body and in what quantity.

Such an analysis can be carried out using a breathalyzer, special test strips and the usual way of laboratory examination. You can buy the above devices without problems at a pharmacy or in specialized stores. It is worth noting that prescriptions and permits are not needed to purchase them.

When using these devices, it is necessary to understand that sensors do not always show accurate result, as there is a possibility of error. The most accurate information can be obtained only in the clinic. Therefore, you should not completely trust these figures. Of course, the devices will not be able to determine the concentration of alcohol, but the fact of intoxication will be confirmed.

Test strips

Testing for the presence of alcohol with test strips is a fairly effective method of research, but it can only determine the presence of alcohol intoxication, but the exact amount of alcohol consumed is not.

To use the test, one does not need to have any special knowledge and skills. The test strip must be removed from the individual packaging and placed in saliva. Within a few minutes, you can see the result. The color of the strip depends on the degree of intoxication. To understand how much alcohol is contained in the body will help a special scale, which is in the instructions for the device. In order for the result to be as accurate as possible, it is necessary to test 15-20 minutes after eating and drinking. It is important to note that such a test is a one-time use, so re-use is not possible.

Often, the measurement range of such a device includes values ​​of 0-2 ppm. This is enough to understand whether it is possible to get behind the wheel or whether it is worth giving up the trip. The price of such devices is quite acceptable and accessible to everyone. In addition, they are easy to use, so every driver should have such a thing with him.

The use of special tubes

It is possible to determine the concentration of alcohol in the body using special tubes. One such device is designed for one application. Outwardly, this is a tube sealed on both sides, and inside it is a layer of a special substance that reacts with alcohol, aldehyde, hydrogen sulfide and acetone.

The tube must be opened before testing. This is done using the tool that comes with the kit. A mouthpiece is put on one end of the tube, and a respiratory balloon is put on the other end. The mouthpiece is placed in the mouth, after which you need to take a deep breath so that the balloon is completely filled. If there is alcohol intoxication, then the yellow indicator will turn green. Shades of green allow you to understand the degree of intoxication. The cost of the tube is not too high, and the application is quite simple.


Breathalyzer is a fairly common device that can be used to determine the level of alcohol in the body. It is important to understand that the result of the study in most cases depends on the type of device and its technical characteristics.

Each breathalyzer has a special sensor that reacts to ethanol molecules. There are several types of breathalyzer, each of which has a different type of meter. The most accurate devices are breathalyzers with semiconductor and electrochemical sensors. Such devices can be used for a long time, they are simple and easy to use, and do not require any additional settings. The result of such a device will be visible after a few minutes.

There are devices with an infrared detector that are designed for testing in clinical settings. Determining the concentration of ethanol in the body takes a lot of time, since the indicators depend on temperature. In the event that all execution rules are followed, the result will be as accurate as possible.

Semiconductor breathalyzers can hardly be called popular, because in addition to ethanol, they also react to other substances. As a result, the result will be in error. In addition, such a device needs constant adjustment.

Breathalyzers have several groups that differ in the accuracy of the result and the allowable number of tests per day. Traffic police officers use professional devices that have a minimum error. Such devices allow you to test up to 200 times a day. It is worth noting that you can buy such a breathalyzer for home use, but it costs a lot.

Personal appliances are intended for use in the home. The breathalyzer can show the correct and accurate result only if all the operating rules are followed. No more than three tests per day are allowed. If you use the device more often, it will soon fail.

The most relevant and popular devices are those that determine the fact of intoxication by exhaled air. But in this case, they will not be able to determine the exact amount of alcohol.

LEDs have three colors: green, yellow and red. Green indicates that there is no alcohol in the body. Yellow shows that there is a small amount of ethanol in the body, and red shows that the person has a critical degree of intoxication.

To be absolutely sure of your sobriety, you should give up alcohol completely. It is worth noting that not every driver is ready for such a decision, so it is important to always follow two rules: control the amount of alcohol consumed and do not drive while intoxicated.
