With diabetes, constant monitoring of blood sugar is necessary. The patient should purchase a glucometer and take regular measurements. How to use the meter correctly to get reliable results?
Glucometry should be performed for type 1 and type 2 diabetes. The glucometer minimizes the frequency of visits to the clinic for laboratory tests. The device is compact and easy to use. With it, you can perform analysis at home, at work, on vacation.
A regular study is also recommended for people at risk, in particular:
- genetic predisposition to diabetes,
The frequency of glucometry is determined by the doctor individually, depending on the type and stage of development of the disease.
- For insulin-dependent diabetes, the analysis should be performed 3-4 times a day.
- Patients with type 2 diabetes need to be diagnosed 2 times a day.
- Patients whose blood glucose concentration is unstable may require more frequent monitoring.
The maximum number of studies is 8 times a day.
Setting the meter
The meter can be used independently by the elderly and even children. The device does not require special skills. Basic setup is carried out only before the first use of the device. It is required to prepare the necessary materials and accessories.
First you need to code the device. Depending on the model of the device, it can be automatic or manual. When you purchase a glucometer, the packaging of test strips is attached to it. A code plate resembling a small chip is attached to it. Insert it into the designated slot. A code of several digits will appear on the screen. Check it with the number on the package. If it matches, the encoding is successful, you can start the analysis. Otherwise, you will have to contact the seller’s service center or the store.
Set up a piercing device. Depending on the calibration of the glucometer, blood sampling can be carried out in the area of the finger, palm, forearm, abdomen or vein. A single-use sterile needle is placed in the piercing pen. Using a special mechanism (spring and retainer), the puncture depth is determined. It must be set taking into account the age of the patient and the individual characteristics of the skin. For example, for children choose the minimum length of the needle: their skin is thin. The longer the lancet, the more painful the puncture.
How to use the meter?
Today, manufacturers of glucometers are constantly expanding the range of such devices. They are issued more and more convenient, compact, having different functions. However, the principle of their operation is almost the same, without taking into account some specifics, which can vary depending on the model of the device and its manufacturer.
There are rules for using the device:
- The device requires compliance with the rules specified in the instructions. So, the device should be protected from mechanical damage, from temperature extremes, from contact with liquid, and high humidity should be avoided. As for the test system, special care is required here, since test strips have a certain shelf life.
- When taking blood, you should follow the rules of personal hygiene to avoid infection. For this, before and after the puncture, the required area on the skin is disinfected with disposable wipes containing alcohol. The puncture should be made only with a disposable sterile needle.
- The usual place for the puncture is the tips of the fingers, occasionally a puncture can be made in the abdomen or forearm.
- The frequency of monitoring the level of blood sugar depends on the type of diabetes and the characteristics of the disease. This frequency is determined by the doctor.
- At the beginning of using the device, you should compare the results of its readings with the data of laboratory tests. For this, the first time should be once a week to donate blood for analysis. This procedure will allow you to identify errors in the readings of the meter and, if necessary, replace the device with a more accurate one.
How to use the meter:
- A needle is inserted into the pen intended for the puncture, after which the depth of the puncture is determined. It should be borne in mind that with less depth of puncture the pain is weaker, however, there is a risk of not getting blood if the skin is too thick.
- The device turns on, followed by a short period during which the device checks its activity. There are models with automatic inclusion, which occurs at the time of installation of the test strip. At the same time, a message is displayed on the screen that the device is ready for use.
- The skin should be treated with an antiseptic, and then a puncture should be made. When using the pen, the puncture is performed automatically after pressing the "Start" button.
- A drop of blood is applied to the test strip. When using a photometric apparatus, blood should be carefully applied to the test strip. When using an electromechanical device, the edge of the test strip is brought to the protruding blood, and the device starts to diagnose the blood itself.
- After a certain period of time, the duration of which depends on the model of the meter, you get the results of the analysis. If the device showed an error, you will have to repeat the procedure.
Models and manufacturers of glucometers
Today, many glucometers from various manufacturers are produced, which are worth paying attention to, since they have a lot of advantages and a minimum number of disadvantages.
For example, not so long ago glucometers from Johnson & Johnson (One Touch Select Simple) and Roche (Accu-Check) appeared on sale. These appliances are the latest in modern design. However, this factor in no way affected the principle of their action.
It should be noted photometric devices from the company Roche - Accu-Chek Go and Accu-Chek Asset. However, you should be aware that such devices have a large error in performance. Therefore, the leaders among glucometers still remain electromechanical devices. For example, One Touch Select Simple has quite attractive features. Although the settings of this device will have to be done manually. Today, many devices carry out settings in automatic mode.
When choosing a glucometer, you should not give preference to its manufacturer, name and appearance, but first of all it is worth paying attention to its functionality and ease of use, as well as the accuracy of the readings.
What the meter shows
In the human body, carbohydrate food, when digested, breaks down into simple sugar molecules, including glucose. In this form, they are absorbed into the blood from the digestive tract. In order for glucose to enter the cells and provide them with energy, an assistant is needed - the hormone insulin. In cases where the hormone is small, glucose is absorbed worse, and its concentration in the blood remains elevated for a long time.
The glucometer, analyzing a drop of blood, calculates the concentration of glucose in it (in mmol / l) and displays the indicator on the screen of the device.
Blood sugar limits
According to the World Health Organization, indicators of sugar content in capillary blood in an adult should be 3.5-5.5 mmol / l. The analysis is done on an empty stomach.
In a prediabetes state, the meter will show a glucose content of 5.6 to 6.1 mmol / L. Higher rates indicate diabetes.
In order to get accurate readings of the device, it is important to learn how to use the glucometer of the current model before using it.
Before first use
Buying a device for measuring glucose in the blood, it makes sense, without leaving the store, get and read the instructions. Then, if you have questions, the on-site consultant will explain how to use the meter.
What else needs to be done:
- Find out how often you need to do the analysis and stock up with the necessary amount of consumables: test strips, lancets (needles), alcohol.
- Get acquainted with all the functions of the device, learn the conventions, the location of the slots and buttons.
- Find out how the results are saved, is it possible to keep a log of observations directly in the device.
- Check meter. To do this, use a special control test strip or liquid - an imitation of blood.
- Enter the code for the new packaging with test strips.
Having learned how to use the meter correctly, you can begin to measure.
The procedure for testing blood sugar using a portable glucometer
Without fuss and haste, follow these steps:
- Wash your hands. If this is not possible (on the go), use a sanitary gel or other disinfectant.
- Prepare the lancing device by inserting a disposable lancet.
- Moisten a cotton ball with alcohol.
- Insert the test strip into the slot of the device, wait until it is ready for use. An inscription or icon appears in the form of a drop.
- Treat the area of the skin you are piercing with alcohol. Some glucometers allow taking samples not only from the finger, this will be indicated in the instructions for the device.
- Using the lancet from the kit, make a puncture, wait for a drop of blood to appear.
- Bring your finger to the test portion of the test strip so that it touches a drop of blood.
- Hold your finger in this position while the countdown is on the meter screen. Fix the result.
- Dispose of the removable lancet and test strip.
These are general guidelines. Let us consider in more detail the features of popular models of devices for measuring sugar levels.
How to use the meter
A glucometer is an individual medical device that allows you to accurately determine the percentage of sugar in a person’s blood. Learn how to use the meter in more detail ..
Of course, most likely most people operate it correctly, but the technical condition of the device must be periodically monitored. Do not neglect this procedure.
Meanwhile, some professional buyers are looking at food labels before buying, in order to discover the cherished number of Brix, and secretly hoping that they can find direct indications of the benefits or harms of the contents of the package for the diabetic.
But among the many well-known terms written there, customers will find, for example, that the product's Brix number is in the range of 14-16 units. Let's go back to the glucometer. It happens that a different working device produces dubious results. The reason for this may be that the meter is used with some violations.
How to use the Accu-Chek meter
Glucometers of this brand are suitable for patients with diabetes of the first and second type. Accurate measurement results will be obtained in just 5 seconds.
The benefits of the Accu-Chek meter for the consumer:
- manufacturer lifetime warranty
- large display
- The package includes test strips and sterile lancets.
The above instructions on how to use the meter are also suitable for the device of this brand. It is only worth noting some features:
- To activate the meter in a special slot, a chip is installed. The chip is black - once for the entire duration of the meter. If it was not preinstalled, a white chip from each pack of strips is inserted into the slot.
- The instrument turns on automatically when a test strip is inserted.
- The skin puncture device is charged with a six-lancet drum that cannot be removed before all needles are used.
- The measurement result can be marked as received on an empty stomach or after eating.
The meter is supplied in a pencil case, it is convenient to store and transport along with all materials.
Errors during the measurement
In preparation for the measurement, as well as during the measurement, the user may make some errors:
- Incorrect encoding of test strips. At the manufacturer, each batch is calibrated by special means. In each of the calibrations, there may be certain deviations. Therefore, for each new batch of test strips, they assign their own encoding, which must be independently entered into the meter. Although in modern devices, the code is already recognized automatically.
- Measurements at too low or too high temperature. Normal, the temperature range for measurement should be considered in the range of 10 - 45 ° C above zero. You can’t take blood from a cold finger for analysis, since at a low body temperature, the concentration of glucose in the blood rises slightly, and the result will not be reliable.
- Using the appliance with dirty handsas well as contamination of the test strips or the device itself.

How to use the Accu-Chek Active meter
Asset system differs from the previous one in several ways:
- The meter must be encoded every time before using a new package of test strips with an orange chip in the pack.
- Before measuring, a new single lancet is installed in the puncture handle.
- On the test strip, the area of contact with a drop of blood is indicated by an orange square.
Otherwise, the recommendations coincide with how to use the Accu-Chek glucometer of any other model.
Rules for using the meter
The analysis algorithm.
- Wash your hands with soap.
- Insert the test strip into the connector. Some devices must first be turned on, others start automatically after the strip is installed.
- Activate blood circulation: massage the selected area, warm, shake hands. Sanitize the skin. Use an antiseptic solution or alcohol wipes.
- Make a puncture with a prepared scarifier. Blood sampling is carried out from the ring finger, retreating 5 mm from the nail plate.
- Wait for the drop sign to appear on the screen and apply blood to the test strip. Electromechanical devices absorb the right amount of fluid. In the devices of the photometric principle, blood is applied to the working area of the tape.
- A countdown or a wait icon will appear on the monitor. After a few seconds or minutes, the result will be displayed.
- Remove the test strip and needle from the scarifier and discard. Their repeated use is unacceptable.
Sometimes the meter records an error due to a malfunction of the device itself, damage to the test strip or improper use. When you save the warranty card, you will receive advice and service in the service center.
One Touch Blood Glucose Measurement System
Using the Van Touch meter is even simpler than the ones described above. The meter features include:
- lack of coding. The desired value of the test strip code is selected from the menu with the button,
- the device turns on automatically when a test strip is installed,
- when turned on, the result of the previous measurement is displayed on the screen,
- the appliance, pen and strip container are packed in a hard plastic case.
The device reports an increased or insufficient glucose level with an audible signal.
Whatever device you prefer, the concept of the study remains the same. It remains to choose a monitoring system to your liking. When evaluating subsequent costs, you need to consider the cost of consumables, not the device itself.
In order for the meter to function properly for a long time, you must follow the rules of use.
Create optimal storage conditions. Do not violate the temperature regime, protect the device from damage and moisture.
Consumables. Depending on the type of device, original or standard test strips must be purchased. They need to be stored properly. Typically, the shelf life of test strips after opening the package is from 1 to 3 months. The box must be tightly closed.
Have regular hygiene devices, handles for piercing and a protective case. The device is not recommended to be wiped with alcohol-containing agents.
The meter is very convenient and easy to use. It will help you independently conduct an accurate analysis of blood glucose levels. Adhering to the operating recommendations, you will prevent breakdowns and increase the life of the device.
