Which meter is better to buy for yourself?
Today they specialize in the production of medical equipment many companies. Glucometers are related to high importance because it makes life easier for people with diabetes. Confidence is a result of products of trusted brands.
The German chemical and pharmaceutical company was founded in 1863, today its headquarters is located in Leverkusen. She invented the drug Aspirin, polymers polyurethane and polycarbonate. Today, Bayer AG is the largest manufacturer of medical devices, including glucometers.
Abdott Diabets Care
The English company Abdott Diabets Care, as it becomes clear from the name, takes care of people suffering from diabetes. It offers devices that control blood glucose with using advanced and accurate analysis methods. Blood glucose meters this brand are fast and require less blood for checks.
Diamedical is growing and constantly expanding. proposed product range. British manufacturer medical products occupies a strong position in the Russian market. Glucometers of this brand are distinguished by attractive cost and a large set of test strips and lancets.
Swiss company Bionime, founded in 2003, offers glucometers, test strips and lancets for them. They are called to do checking your blood glucose is safer and easier for the average person, so the analysis is carried out without special training.
Asian manufacturer of medical products TaiDoc offers inexpensive glucometers for home use. Since 2005 the company operates in the Russian market, distributing through official manufacturers. Glucometers of this brand allow you to take blood from the finger, thigh, forearm.
Types of glucometers
A regular blood test is required for people suffering from endocrine diseases. Manufacturers offer different types glucometers for accurate and quick analysis. They designed to detect abnormalities. Thereby a person can quickly take the necessary measures.
Glucometers are divided into categories:
Each category is distinguished by its inherent features and principles of work. Manufacturers use the latest advances to increase the accuracy of the analysis.
This type of meter is considered convenient and popular. They using amperometric or coulometric analysis method blood. To determine the level of glucose in the blood through a sample on an electric current is passed through the test strip, after which the device conducts analysis of indicators. The higher the current, the more sugar in blood.
high functionality and accuracy of measurements;
ease of use even for children and the elderly;
high measurement speed – 5-10 seconds;
minimum amount of blood for analysis.
strips need to be analyzed quickly, otherwise they stop to be active;
electronic encodings are difficult for some people.
Such devices simplify the analysis procedure because the patient is not you need to independently compare the colors on the test strip. Some models additionally analyze cholesterol or triglycerides in the blood.
Such devices demonstrate analysis results using special test zones. They are considered reliable, so many prefer these analyzers. Feature of work lies in the fact that the device independently determines the color analysis and compares it with the scale. He is able to translate color indicators in a specific number format for convenience.
simplicity and reliability in use;
the ability to save analysis indicators or transmit to computer;
replacement of needles, lancets and strips from the kit.
short-lived and easily fail;
temperature differences give an error in measurements
These mini home analyzers came first on the market. They eliminated the need to analyze independently color scale. But photometric glucometers are already gradually disappear from the sale.
Non-invasive blood glucose meters
Such glucometers are sometimes called Romanovskie or optical. They are able to determine blood sugar levels without blood sampling for analysis. For this, muscle tone and pressure are checked. Separate models also use ultrasonic, electromagnetic and thermal waves to obtain the necessary information, or spend spectral analysis of the skin for the allocation of sugar.
no need to pierce the skin and take blood for analysis;
the possibility of continuous monitoring;
good measurement accuracy.
- high price.
Non-invasive blood glucose meters are a new word in the industry, but these devices not yet available. In addition, analysis methods have not yet been fully honed, so errors occur. But you can with confidence to say that in the near future they will occupy part of the market.
The principle of operation and device glucometer
Design features and operating principles depend on a specific model of the meter. But they are for one purpose and use one blood test method. Used for a long time devices that pierce the skin on the finger and analyze blood with using special test strips. These strips are the key. element, because their surface is covered with a special reagent. Thanks to him, the sample is painted in a certain Colour.
The glucose level is determined by the color spectrum. Used to for this had to use a special scale, but modern glucometers are able to independently evaluate the results and give out specific numbers. For information, a test strip is inserted. into a special slot on the device.
Photometric and electrochemical glucometers use other blood test methods. The first determine the amount of sugar by the color range of the reagent, and the latter pass electric current and determine the resistance. This allows you to get accurate results. on the basis of which the necessary decisions are made in the future.
Glucometer Selection Options
Household glucometers are important for people suffering from sugar diabetes, high cholesterol, or other similar problems. TO issues of choosing a specific model are suitable from all responsibility. Doctors identify several options. glucometers:
a method for calibrating an analysis result;
the amount of blood required for analysis;
accuracy of the results;
amount of internal memory;
additional parameters for measurement.
Based on this, an assumption is made about how the device will be effective and convenient in home use.
Result Calibration Method
Each meter uses a specific blood test method. There are two options:
in plasma – venous blood is required for verification;
by capillary blood – blood from finger, thigh, forearm.
The first method is accurate, but it is applied on specialized glucometers when errors cannot be allowed. The second method is simple for everyday analysis, but it gives errors. In the capillaries, the sugar content is 10-12% lower, therefore it is used the corresponding coefficient is 1.11.
Amount of blood required
Each model requires a specific blood volume for analysis. is he measured in several milliliters. Accurate and modern glucometers do not require deep punctures, so the procedure brings less discomfort. Remember that with age, capillary circulation blood is broken, so older people need 2-3 μl The rest of the people need no more than 1.5 μl.
The accuracy of the results
The most important parameter on which the meaning of the procedure depends. Even modern home blood glucose meters cannot be compared in accuracy with laboratory research. In some cases, the error reaches 15-20%, and this is permissible. Measurement accuracy is reduced. due to various factors. To minimize errors, testers and analysis methods are used, as well as special encodings to duplicate the results.
This parameter shows how long the meter takes. to get the results. Modern models cope for 5-6 seconds, but even simple devices rarely need more than 10-12 seconds. This is not such a critical indicator.
The amount of internal memory
Modern devices are used for verification and maintenance “medical history.” Many models store analysis results that allows you to track changes and dynamics. Stored in memory until 500-600 checks, but for some glucometers the volume is designed for several thousand records. This is useful for those who keep a diary or tracks changes over a long period of time. Besides, Information is transferred to the computer via the USB port.
Additional parameters for measurements
Separate models show blood sugar and blood pressure, muscle tone, cholesterol. This allows take a comprehensive approach to health monitoring.
Which meter to choose?
If there are no serious health problems, and a glucometer is required only for prevention, then a simple photometric is suitable A model without an abundance of additional features. 500 memory capacity enough records to track changes over the Nth period of time.
For continuous monitoring of glucose levels in people with the first stage diabetes mellitus electrochemical glucometers are suitable. It’s better choose a device with test strips to increase accuracy.
People with stage 2 diabetes and obesity require functional devices. Better choose models that are capable of analyze blood parameters and blood pressure.
Elderly people should consider the characteristics of the body and existing health problems. But in any case they are suitable devices with a large screen and simple controls. Volume of withdrawn blood should be at least 2-3 μl to ensure accuracy.
How much does a glucometer cost?
Plasma-calibrated electrochemical glucometers cost from 600 rubles.
Blood-calibrated electrochemical glucometers cost from 900 up to 1600 rubles.
Plasma-calibrated photometric glucometers cost from 600 up to 4000 rubles.
