Urine analyzers. Use of urine analyzers in qualitative prevention research

Urinalysis is one of the most important diagnostic tests. With its help, you can determine not only deviations from the norm in the functioning of the urinary system, but also identify a number of other serious diseases. Based on this analysis, an experienced doctor can confirm or deny the presence of a large number of different ailments in a patient.

Types of urine analyzers

In the past, all laboratory tests of urine were carried out manually, so this process was quite labor-intensive, and its results were not always objective. With the advent of automatic and semi-automatic urine analyzers, it has become possible to quickly obtain more accurate data and identify even minor deviations in the composition of urine.

Semi-automatic analyzers, as a rule, are small in size and can operate both from the mains and autonomously (with the help of batteries). They are simple and reliable in operation, do not require additional special maintenance, do not require long preparation for work, and display the results of the analysis performed on the display (they can, like automatic analyzers, transfer data to paper).

Automatic analyzers make it possible to conduct a complete automated urine examination in a short time. At the same time, the reliability and validity of the analysis performed is significantly increased. The process itself is quite simple. It is enough to place the test strip in the automatic feeder, which will load it into the measuring module. There, the device will very quickly scan the strip and then display the result on the monitor. The strip itself will go into a special waste collection container.

Features of automatic and semi-automatic analyzers

The digital system built into the semi-automatic analyzer completely eliminates any errors during the research process. With the help of such analyzers, it is possible to very quickly obtain analysis results for several parameters at once. The productivity of the devices is from 120 to 150 tests in one hour. Loading is carried out one strip at a time. Semi-automatic memory - up to 1000 results. Compared to automatic analyzers, the price of semi-automatic devices is significantly lower.

The performance of an automatic urine analyzer is several times higher than that of a semi-automatic device. It performs approximately 500 analyzes on 10 parameters per hour. The advantages of automatic equipment for urine analysis are the high accuracy of the tests performed, the speed of the study and ease of use. Automatic analyzers with the ability to connect to a computer are especially convenient. Full automation of such devices minimizes the participation of personnel and significantly reduces the time of analysis, which completely eliminates the unreliability or subjectivity of the information received.

Automatic devices, unlike semi-automatic ones, enter all the required research parameters independently, and the finished results are transferred to the computer memory. This greatly simplifies the processing and transmission of data, as well as their storage.

A urine analyzer is an electronic, automatic or semi-automatic device that allows you to quickly study biomaterial according to specified parameters. A urine test is one of the mandatory tests that is prescribed to a patient when going to the hospital. The process of urine analysis has always been routine and labor-intensive, but the use of devices ensures prompt data acquisition and reliable results, eliminating errors and inaccuracies.

Classification of urine analyzers

Analyzers can be divided according to the following parameters:

To size.
To automate the process.
In terms of performance.
According to the research method.

By size:

portable;
mobile;
stationary.

Portable devices fit in the palm of your hand and can be carried with you, designed for home use. Such models do not have a built-in thermal printer; the results are displayed on the LCD display. Test strips are used for testing. Mobile devices are more professional, weigh from 1.5 to 2.5 kilograms and have a built-in thermal printer, which allows them to be used right at the patient’s bedside. Such analyzers are especially popular among field specialists. Stationary models are high-performance, have dimensions and characteristics that are inconvenient for constant transportation, and therefore are used in laboratories of various levels.
For process automation:

semi-automatic;
automatic.

The main difference is in the sample submission process. For semi-automatic instruments, the preparation and submission of samples to the compartment is carried out by a laboratory assistant; one sample is supplied for each study. In automatic models, samples are placed in groups, these can be racks with test tubes or carousels with test strips. This method significantly reduces processing time, which is especially important in laboratories and clinics with a large flow of biomaterials.
By performance:

up to 20 tests per hour;
up to 150 tests per hour;
up to 1000 tests per hour.

A performance of up to 20 tests per hour is typical for portable devices. The equipment produces up to 150 tests per hour, suitable for small clinics and laboratories. High-performance analyzers are designed for laboratories, centers and clinics with high traffic volumes.

According to the research method:

based on the dry chemistry method;
based on flow analysis;
complex methods of analysis.

For analysis using the dry chemistry method, special test strips with applied reagents are used, which change color upon contact with liquid. In flow analysis, a quantitative count of elements and microorganisms in urine per unit volume is carried out. Allows you to identify diseases that occur covertly. Complex analysis methods use instruments that combine different techniques. This allows you to more fully assess the condition of the body.

Areas of application of analyzers

They are used both privately and in regional medical centers, laboratories and clinics at various levels. Suitable for use in remote communities where there are no doctors and monitoring of indicators is necessary. They allow you to quickly identify drug and alcohol intoxication and are included in the list of necessary equipment for visiting specialists in drug treatment clinics. A number of standard models are suitable for use in veterinary medicine, but there are special modifications for this area.

The analyzers are convenient and easy to use. When purchasing a device from a specialized company, managers will provide the necessary instructions on how to use the equipment. A detailed description of the operation and maintenance of the device is in the attached instructions.

Significance in diagnosis

A general urine test is one of the primary studies, which reveals abnormalities in the functioning of the liver, kidneys, urinary tract, cardiovascular and endocrine systems. Urine is suitable for analysis within 2 hours after collection, since organic compounds break down into simpler ones over time, and this leads to incorrect data. The use of analyzers allows you to quickly and reliably identify deviations in the functioning of the body. Based on the results, a diagnosis is established, signs of the disease are identified in the early stages, monitoring the patient’s condition and assessing the effectiveness of treatment are simplified.

Principle of operation

Most urine analyzers use the “dry chemistry” method. It is simple and requires a minimum of preparation and action from the laboratory assistant. The source of information is a test strip with applied reagents; they can be from 1 to 14. The strip is treated with urine, then placed in the apparatus. The feedback of indicators on the biomaterial is read by special optical elements, then the data enters the module, which collects the information and converts it into digital form. Next, a comparative analysis of the obtained data with the normative ones takes place and the final information is displayed on the screen or printed.
The analysis is deciphered by a doctor, but special programs have been developed for a number of models that integrate with a computer. Using this software, you can immediately get feedback on the pathology and a description of the possible causes of its manifestation. If it is not possible to visit a doctor, you can decipher the data online using special resources.
