How to tell if the blood glucose meter is accurate for diabetes monitoring?

Diabetic patients who want to monitor their blood sugar can choose to go to a regular hospital for venous blood testing, so when comparing the test results with the blood glucose meter, if the error does not exceed 10%, it means that the blood glucose meter is more accurate. In daily life, many diabetics will choose to prepare their own blood glucose meter at home, which is also to facilitate the understanding of the blood sugar level in their body, if the blood glucose meter is not accurate, it is also very unfavorable to observe blood sugar. If you don't want to go to the hospital for blood testing, you can also choose to take the blood glucose meter to a professional place for testing.

There will also be certain differences in the way blood glucose meters are collected, some blood glucose meters use blood-sucking type, while some blood glucose meters use blood-wiping type. <>

If the blood glucose meter is smeared with blood, the amount of blood collected will be larger, and the patient will also feel pain, if the blood volume is insufficient, it will affect the results of the test, and it is also a waste of test strips, so many diabetic patients will choose to buy a blood-sucking blood glucose meter, which only needs a drop of blood to measure the blood sugar level in the body, and the operation is also very convenient. <>

There will also be errors in blood glucose meters on the market, and professional institutions are also relatively loose in the test range of blood glucose meters, if the measurement results are not too different, they are qualified products. The reason why there will be errors, this is also caused by incorrect operation, some blood glucose meters are relatively close in the operation process, patients want to test blood sugar, must read the instructions in advance. <>

If the blood is not collected properly, it will also affect the test results, so be sure to keep it clean and tidy before using the blood glucose meter, if the blood glucose meter is contaminated by dust or debris, it will affect the test results. Before using the blood glucose meter, you must take regular care of the blood glucose meter, in addition to testing your blood sugar at home, you should also go to the hospital regularly for checkups.

There are two ways to determine whether a blood glucose meter is accurate or not:

1. Quality control fluid test, the dealer buys blood glucose test strips, the manufacturer will give the dealer quality control solution, the quality control solution simulates blood, when using blood glucose test strips, add the quality control solution dropwise to see if the range is within the range of the quality control solution. If it is there, the blood glucose meter is normal, if it is not there, it can be handed over to the manufacturer for warranty (warranty period of 5 years).

2. Use a biochemical instrument for comparison, which is also the most accurate and effective method. The first is only the test of the blood glucose meter manufacturer.

Biochemical instruments are generally available in large hospitals or diabetes hospitals.

The method of detecting whether the blood glucose meter is accurate is to compare it with the blood glucose results of the venous blood test, and the error is within 10%, that is, the blood glucose meter is about 10% lower than the blood glucose value of the venous blood draw, indicating that the blood glucose meter is accurate.

The blood glucose meter needs to be maintained during use, stored in a dry place at room temperature, avoid exposure to the sun, freezing or violent vibration, so as not to affect its accuracy, and pay attention to cleaning the blood glucose meter regularly.

If a problem with the meter is suspected, the meter may need to be corrected or a blood glucose test strip may be tested.

It can be judged by the principle of the blood glucose meter, the detection process of the blood glucose meter and the value of the test, and multiple tests can also be performed.

It is better to buy a blood glucose meter to measure diabetes. This is because diabetes is a relatively common disease that can lead to other conditions. And it's hard to be thorough**. Therefore, buying a blood glucose meter for measurement has the following benefits.

1.First of all, diabetes buy a blood glucose meter to measure your blood sugar, so that you can always know what kind of physical state you are at this moment. Because whether a person is sick or in any other situation, the most important thing is to understand what kind of state he is in at this moment.

Then the same is true for diabetics. We must know how we are in recent form, and then we are not completely feeling through ourselves. Therefore, it is best to buy a blood glucose meter to measure.

In this way, we can know our truest feelings, and we can know our best state.

2.And if you buy a blood glucose meter to measure your diabetes, you can also know your drug dosage very well. Because diabetes is the same as any other condition.

Sometimes you need to take more medicine, but sometimes you need to take less. Therefore, it is necessary to adjust according to your blood sugar level. At this time, it is necessary to buy a blood glucose meter and measure some blood sugar.

Because you can always know what your body is like. You can also know how much medicine you should take at all times. So buying a blood glucose meter to measure yourself is a must.

3.And one of the most important things is that for diabetics, the level of blood sugar may be more important to them than to eat. You can know what kind of state you are in based on your blood sugar.

You can also know what kind of diet you should go with based on your blood sugar level. Therefore, for diabetics, the blood glucose meter is measured at home, which can make the diabetic feel a kind of comfort in his heart. It can also allow the diabetic to better understand himself.

Therefore, it is necessary for diabetics to buy a blood glucose meter to measure it.

Most people talk about diabetes because it reduces the body's resistance, destroys blood vessels, affects organs, and greatly affects people's health and quality of life, but early detection and intervention can greatly reduce function and organ damage.

According to Xia Rujie of the Laboratory Department of Chengdu Second People's Hospital, glucose is metabolized in the body through a series of chemical reactions such as aerobic oxidation, anaerobic digestion, and pentose phosphate pathway, providing the energy and important substances required for the body's physiological activities. It can also be anabolically converted to glycogen and stored in liver or muscle tissue, where it can be quickly broken down to replenish blood sugar when the body needs it. In addition, non-sugar substances in the body such as lactic acid, amino acids, glycerol, etc., can also be converted into glucose or glycogen through the gluconeogenesis pathway.

Diabetes can be diagnosed when fasting blood glucose, or 2-hour blood glucose in oral glucose tolerance test, or random blood glucose, and diabetes symptoms at the same time (any of them should be repeated on another day if any of them are abnormal), and one of the three items exceeds the value, so blood sugar is the key to diagnosis.

Many friends always have a blood glucose meter at home, which is convenient and fast, and can monitor blood sugar in time. But at the same time, we would like to remind everyone that for this kind of inspection instrument, we need to pay attention to its detection accuracy, and we need to find after-sales maintenance regularly, and periodically do a good job of comparing the test results. "Xia Rujie said.

If it is just an ordinary measurement, it is more convenient for buyers to use, and the Ukese blood glucose meter is on the line, and it is easy to use, if the condition is serious, it is recommended to be hospitalized**.

The accuracy of the blood glucose meter used in the general hospital will not be bad, but the blood glucose meter is generally more easily affected by the operation Therefore, the usual monitoring must be standardized, the blood glucose meter cannot be more accurate than the biochemical instrument, and the usual monitoring If the test is still very high or very low, you must contact the doctor immediately.

Hello, first of all, tell you the national standard of the current blood glucose meter:

When the test blood concentration is below 75mg dl, the allowable deviation is 15mg dl**, which is converted to a commonly used unit in China, and the unit conversion is 1:18, that is, 1mmol l = 18mg dl

When the test concentration blood is above 75mg dl, the allowable error is within 20%.

For example, let's say your blood sugar level at the time of the test is 100mg dl (i.e. The range of test results with a blood glucose meter should be within 80 to 120 mg dl (considered normal. The national standard requirements are relatively relaxed, so there are more blood glucose meters with average accuracy on the market.

It is best to choose a blood glucose meter with brand guarantee, and many international brands of blood glucose meters can control the error within 10%.

In addition, the blood glucose meter itself is a POCT rapid detection instrument, and its accuracy is definitely different from the hospital's biochemical instrument. (A good biochemical instrument, such as the YSI biochemical instrument in the United States, can control the error within 5%)).

However, the blood glucose meter is simple to operate, relatively low in cost, suitable for home use, and eliminates the trouble of often running to the hospital.

If you have any questions, please continue to ask, I hope it will be helpful to you.

I am your sugar friend, I also have a blood glucose meter, as long as it is operated correctly, the measured blood sugar value is basically correct. However, the blood in the capillaries measured by the blood glucose meter is a little different from the venous blood glucose.

I asked an expert in this area, and he said that blood glucose meters are more accurate than blood tests.
