How can there be a mistake in the test of the Sannuo blood glucose meter and the medical doctor s bl

Hello, may I ask what you are comparing with above, if it is compared with the blood glucose meter in the hospital, it is not comparable. If it is higher than that of a biochemical machine, what is the blood sugar concentration you are measuring? According to the national standard, more than 95% of the test results meet the 75mg dl (the deviation in parentheses is within 15mg dl (when the domestic use unit is below, and the deviation is allowed within 20% when it is higher than 75mg dl).

For example, if the result is 7mmol DL measured by a biochemical instrument, the test results of your blood glucose meter are in line with the national standard. The blood glucose meter is a rapid diagnosis instrument, and it is still very different from the biochemical meter in terms of accuracy and repeatability. I don't know if there are testing units in Beijing, but there are quite a few in Guangzhou.

In fact, as long as it is a large diabetes hospital, there will be a biochemical instrument that can detect it. Since you are buying Sannuo Anwen, it is a code-free blood glucose meter, and only the manufacturer can calibrate it. But you can hit their complaints**, the content is not that the machine is not accurate, but that the test strip is not accurate, remember, the test strip is not accurate!

Those who say that the machine is not allowed are generally laymen, and the customer service will send you away at once. You said that the test strip is not accurate, and you must say that it has been compared with the biochemical instrument. It's a long way off, let them change the test strip, and the machine is no problem and let them change the test strip.

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

Each blood glucose meter has an error value, and the reason for the error will also be related to your operation.

There is no comparison, there is a deviation in the blood glucose meter itself, not to mention your two brands, even if it is Johnson & Johnson Roche, there will be a certain error. Just like a watch, you say your time is accurate, I say the time is accurate, at this time we can only judge by looking at Beijing time and having an accurate reference.

The test results are within a reasonable error of 20%. It's all normal. Hope mine is useful to you.

Reasons for the error in blood glucose measurement by blood glucose meter:1Inconsistency between the blood glucose meter and the blood glucose test strip** will lead to an error in the test, because the test strip cannot be consistent in each batch of response to glucose, so it must be adjusted**; 2.

When collecting blood, use the blood from the fingertip, squeeze it slightly from the base of the finger, and then collect blood.

I measured my blood sugar once and twice this morning, and it took more than a minute to use the same needle, and I used a three-no blood glucose meter. Can anyone explain what's going on, is it my blood that has a problem, or is there a problem with the Sino blood glucose meter.

Instrument or test strip questions:

If the difference is large for three consecutive times, more than 1 means that there is a serious problem with the instrument or test strip. Try again with a new test strip. If the new test strip still has a large error, it is a malfunction of the test strip or instrument.

You can request an exchange at the place where you bought the instrument or test strip (hospital pharmacy or pharmacy). They will contact the first staff of the manufacturer, whether it is a test strip or an instrument, the manufacturer will generally give you a replacement in order to maintain its reputation.

Problems with personal use or operation:

If the difference is within 1 for three consecutive times, it is generally a double problem of operation and blood: 1. The blood glucose measurement value of the three times is not the same, because the blood concentration in the front of the finger and the blood concentration in the last two measurements is different. If there is more serum, the next two measurements will be higher, and if it is new blood squeezed out, the next two measurements will be lower.

2. Blood glucose test strips are very susceptible to the influence of oxygen in the air, and the longer the bottled test strips or individually packaged test strips are placed in the air, the more inaccurate the blood glucose value will be. In particular, bottled test strips are generally used up within three months after opening (oxidase technology). Otherwise, the results of the blood glucose measurement will be inaccurate.

Other than that; Disinfectants such as alcohol or iodophor can also affect the measurement results.

So; Don't use alcohol or any antiseptic solution when measuring blood from your fingertips, just wash your hands and dry them. The first drop of blood is wiped off with a clean cotton wool and measured with the second drop of blood squeezed out. If you measure continuously, do not take out all the test strips at once, take the test strips before the second measurement, and the blood on your fingertips must also be wiped off and a drop of blood must be squeezed out again for measurement.

This way the error will be smaller.

According to the requirements of the national standard for blood glucose meters, the product is compared with the hospital's venous blood drawing, and the error of SINO is generally controlled within 15%, it is recommended that you can go to the hospital for examination first, and if you find any problems, you can contact SINO after-sales service.

In order to get accurate test results, when you use the meter for the first time or replace a new box of test strips, you need to adjust the calibration code of the instrument to match the calibration code on the outer packaging of the test strip. Here's how to set the correction code:

Method 1: Press and hold the "C" button for 3 seconds to turn on the computer, the screen displays the calibration code stored by the current instrument, press the "C" or "D" button to adjust the calibration code, the calibration code flashes at the same time, press the "M" key to confirm, the calibration code stops flashing and turns off.

If the correction code flashes for 1 minute without key action, the system defaults to the current correction code setting and shuts down.

Method 2:1) Insert the test strip directly into the instrument, the screen displays the correction code of the current instrument, and the blood drop symbol flashes.

2) Press and hold the "C" button or "D" button for more than 1 second, the blood dripping symbol will disappear, and the screen will display the current correction code and flash.

3) Press the "C" button or "D" key to adjust the calibration, and find the same correction code as on the test strip.

4) Press the "M" button to save the current correction code, and the blood drop symbol flashes to indicate that the correction code is set successfully.

The error of the Sino blood glucose meter is too much, the credibility is too poor, and the measurement is not accurate.

I just bought a Sino blood glucose meter and I don't know what its correction code is.

The accuracy of measuring fingerstick blood with a blood glucose meter at home is not high, and the accuracy of household instruments is lower than that of professional testing instruments. If it is compared with taking a vein in the hospital, the difference is not too big, and it is normal.

Does this error measure the comparison of fingertip blood and venous blood? There is a difference between the two, and the difference is very small, which is good.

There are two types of Sannuo Anwen, one is the ordinary blue type called Sannuo Anwen, and the other is the Sannuo Anwen code-free type.

Take the ordinary type of Sino as an example.

1 Make sure the positive and negative poles of the battery are installed correctly and the battery is fully charged.

2 Confirm that the keys are normal.

There are two buttons in the Anwen blood glucose meter, and the small key on the left has the function of.

1 Average blood glucose query 2 Past test result query 3 Date and time setting (with right click).

1 Average blood glucose inquiry.

Press and hold the left button (about 3 seconds) and you will hear a dripping sound, and then the "7 d" screen will be displayed in the upper left corner of the screen, and the 7-day average blood glucose value will be displayed in the middle of the screen, and the blood glucose value will be displayed in the middle of the screen to the 28-day average blood sugar value.

2 Past test results query.

3 Date and time setting.

After long pressing the left button, it will display 7d, and then press the right button, that is, the "C" key. Then enter the date setting mode, press the "C" key to adjust the correct time and date (only increase, press more and continue to press back).

C key is the right button Function: Set the code number, the premise of accurate blood glucose test is that the test strip code needs to match the instrument.

Press and hold the C button for about 3 seconds, then the code setting interface will appear, such as C 06 C07 C22, etc., press the C button to adjust the code code until it corresponds to your test strip code code, and then press the left button to confirm, and the instrument will automatically shut down after confirmation.

Make sure your instrument can complete the above steps (the most important is the C-key setting code step), if it can be completed, it means that there is no problem in the initial stage of the instrument.

Next, insert the test strip into the instrument, pay attention to whether the test strip is inserted in the correct direction, and you will hear a drop sound after inserting the test strip. Then the instrument screen will display the code to see if the code matches the test strip. The instrument will then display a flashing blood drop symbol, at which point the blood can be taken for testing.

If the blood drop symbol is not displayed, 1 Confirm whether the test strip is a three-promise stable match test strip 2 The test strip is inserted correctly.

If there is still no blood dripping symbol, it is possible that the insertion port of the instrument is damaged and you may want to return the dealer for a new instrument for retesting.

Directly disassemble and cut the horn wire, a very simple instrument, just two red horn wires, just be careful when dismantling, you don't have to listen to their blind beep.

Paste the horn hole with adhesive tape and paste two layers!

The Anwen blood glucose meter does not need to adjust the correction code, and it is all free of adjustment code.

Features: 1. Glucose oxidase has high specificity, the test strip uses glucose oxidase reagent, which has high specificity, will not be easily interfered by maltose and other carbohydrates, and can accurately reflect your real blood sugar level.

2. Automatic siphon sampling, easy to use, whether the blood glucose meter can correctly add blood to the reaction area of the blood glucose test strip is an important factor in the accuracy of the test.

By simply touching the blood sample with the test strip, the blood can be correctly added to the reaction area of the blood glucose test strip, even if the elderly with a little trembling hands can also accurately complete the blood sample alone.

3. Easy to operate, safe and without code adjustment, you can test by inserting the test strip, and the operation is extremely simple. Automatic power on/off, easy to operate. The automatic retract is not only easy to operate, but also ensures the safety of the user.

4. The independent packaging of the test strip can prevent the test strip from being affected by the external environment and prevent the test error caused by the moisture of the test strip. The Sino Anwen Code-free Blood Glucose Test Strip is individually packaged and has a validity period of up to 18 months, which can avoid unnecessary waste.

5. Only two No. 7 batteries are needed, which is easy to replace, and the No. 7 battery is used in the Sannuo Anwen Code-free Blood Glucose Meter, which can be purchased at any time in the surrounding area, which is convenient and fast.

6. Automatic temperature compensation, adapt to various temperature environments, automatic temperature correction function Sannuo Anwen blood glucose meter has a built-in temperature sensor, which can automatically calibrate the temperature, and the test value will not be affected by the temperature to ensure that the results are accurate.

7. Large screen, huge memory system can view the average of 7 14 28 days, and the elderly with poor eyesight will misread the data. The three-stop code-free blood glucose meter uses a large screen with clear handwriting. The huge memory system can record 220 historical test values at the same time, and can view 7 14 28 day averages to help users better understand blood glucose values.

8. The test strip is cheap, nearly 50% lower than general products, economical, and can save a lot of costs for long-term use.

Sannuo Anwen + blood glucose meters are basically free of adjustment and correction codes!!

Press C, just the same as your test strip batch number, now it's too troublesome to adjust the code, it is recommended to change to a more advanced one.

There's a C button, just press it to tune it up.

Alas! I'm dying, and this device always shows up incorrectly when I follow up my blood sugar, what's going on?

Is the Sannuo Anwen + blood glucose meter code-free?

Please instruct me on how to calibrate the Sannuo Stable Blood Glucose Meter.

How can it only be added and not subtracted?

Stable machine performance: automatic retraction * automatic power on and off * storage of 220 test data * 1 10 drops of sample * accurate and safe * display of daily average. The equipment of the stable blood glucose meter:

1 blood glucose meter * 1 portable case * 1 lance * 1 lance * 1 instruction manual and 1 warranty card 50 test strips and 50 needles. Operation instructions of Sino Anwen blood glucose meter: After inserting the test strip, it will automatically turn on the machine to see whether the displayed calibration code is consistent with the test strip.

Use a lance against the sterilized finger to collect blood (do not sterilize with iodine). The blood suction port of the test strip is close to the blood droplet, and the test strip automatically sucks blood. A 25-second countdown shows the result.

The adjustment method of the correction code of the Sannuo Anwen machine: after inserting the test paper, press the C key to adjust, and after adjusting to the same as the test paper, press the power button (small key) to determine. For more, you can go to the official ** of SINO to check!

If you want to buy, I suggest you go to their Zhengzhou ** store! It's at the west gate of People's Park, 0371-3879698! Their ** is basically the lowest, and many stores go to them to buy! You can check it out!
