Blood Glucose Meter Skills Sharing

1. The accuracy of the blood glucose meter
Try to choose a blood glucose meter that is similar to the test value of the simultaneous venous blood draw, otherwise there will be a tragedy of delaying the disease. The error of the blood glucose meter can be controlled at about 15%. In general, glucometers test finger blood results that are 10% lower than laboratory tests for venous plasma.

2. The convenience of operation of the blood glucose meter
For middle-aged and elderly friends, if you want to choose a blood glucose meter that is easy to operate, you should not be attracted by the many complex functions of the blood glucose meter, but it is best to choose a blood glucose meter with functional storage function, so that you can better understand your blood sugar changes.

3. Operation of the blood glucose meter
For example, whether the lancet is convenient to use, how much blood is needed, the reading time of the blood glucose meter, the size of the display screen and the clarity of the value, whether the battery is easy to replace, whether the size of the machine is appropriate, and so on.

4. The temperature range of the blood glucose meter
Many blood glucose meters have a temperature range regulation, so consumers should ensure that the temperature of the selected blood glucose meter can work normally in the local environment when purchasing a blood glucose meter.

5. use attention
(1) Try to keep it at room temperature.
(2) Avoid placing the instrument near electromagnetic fields (such as mobile phones, microwave ovens, etc.).
(3) The blood collection volume should not be too much or too little (especially the photochemical blood glucose meter).

6. How to collect blood samples with a blood glucose meter?
Wash and dry hands thoroughly. Warm and massage your fingers to increase circulation. Lower your arm briefly to allow blood to flow to your fingertips. Use the thumb to top the interphalangeal joint where blood is to be collected, and then use the lancing pen to puncture the skin on the side of the fingertip. Do not squeeze the skin after piercing, so as not to mix the tissue fluid into the blood sample and cause deviation of the test results.

7. The use needs to be corrected
The blood glucose meter needs to be calibrated after a period of use. It is recommended that the patient ask the hospital nurse to help debug the blood glucose meter, or contact the manufacturer in time to inquire about maintenance. However, the more advanced blood glucose meters are all blood glucose meters using electrochemical methods, which are not easy to be polluted, so as long as they are well protected, they can be used for a long time.

8. The effect of measuring the effect of alcohol is not dry
For patients who are accustomed to using alcohol to disinfect their fingers, measuring blood sugar at home often results in large deviations. Because alcohol is used for disinfection, and when the alcohol is not dry, the alcohol may be mixed into the blood droplets, thereby reducing the glucose concentration in the measured blood, so the measured blood sugar value is low. In addition, many blood glucose meters have certain requirements for blood collection. If the blood volume is too much and the blood fills the absorbent pad, the measured value is high. Conversely, if one drop of blood is not enough to squeeze a second drop of blood, the measured value will also deviate. Therefore, whether there is insufficient blood or excessive blood, the test must be retested with a new test strip to avoid false results.

9. Pay attention to the preservation of test strips
The probability of failure of the blood glucose meter itself is small, but the test strip will be affected by the temperature, humidity, chemical substances, etc. of the test environment, so the preservation of the test strip is very important. To avoid humidity, keep it in a dry, cool, dark place, and keep it tightly closed after use; the test strips should be stored in the original box, not in other containers. Do not touch the test area of ​​the test strip with your fingers etc.

10. Clean before use
When testing blood sugar, it is often polluted by dust, fibers, sundries, etc. in the environment. In particular, the test area of ​​the instrument is accidentally contaminated with blood during testing, which will affect the test results. Therefore, blood glucose meters should be regularly checked, cleaned, and calibrated. Be careful when cleaning the test area. Do not use alcohol or other organic solvents when wiping, so as not to damage the instrument, you can use a cotton swab or a soft cloth dipped in water to wipe.
Knowing how to use the blood glucose meter, Chaosheng Medical reminds you that in addition to paying attention to their own eating habits, the elderly with high blood sugar should also develop a good routine and go to the hospital for regular check-ups.
