Daily blood sugar monitoring is a must for every sugar friend, but sometimes some sugar friends will find that the value they measure at home is quite different from the blood sugar value of venous blood drawn in the hospital.
If the blood sugar is not measured correctly, it may be that you have stepped on these 5 pits
1. The storage of blood glucose meter is unqualified
Placing the blood glucose meter near an area with electromagnetic fields (such as an induction cooker, microwave oven, etc.) for a long time may gradually affect the accuracy of the blood glucose meter. Therefore, it is necessary to avoid electromagnetic fields and choose a cool and dry environment with a certain temperature and humidity to store the blood glucose meter. In addition, it should be noted that the test area of the blood glucose meter should not be contaminated with dust, blood stains, etc., and can be gently wiped with a soft cloth dipped in water.
2. Apply the expired test strips
Failure to pay attention to the expiration date when using test strips may result in skewed test results. It is recommended that you pay attention to the expiration date when buying test strips, sort the test strips with near-expiration date and far-term expiration date, and use them first "near" and then "far".
3. The position of the test strip is incorrect
Some diabetic patients are Xi to pinch the middle of the test strip directly with their fingertips when measuring blood glucose, which can lead to contamination of the test strip and affect the final test result. The correct operation should be to gently hold the sides of the test strip with your fingertips and quickly insert it into the corresponding position of the blood glucose meter.
Fourth, the wrong choice of disinfectant
Some diabetic patients use iodophor to disinfect, but iodophor reacts easily with the oxidase enzyme on the test strip, which can affect the results. Therefore, when performing blood glucose testing, 75% alcohol should be selected as a disinfectant, and ensure that blood is collected after the alcohol has evaporated, so as to avoid alcohol diluting the blood sample and affecting the accuracy.
5. The collection method is wrong
The process of collecting blood samples is critical, and the slightest mistake can affect the results. The correct collection method is as follows:
1. Use 75% alcohol to disinfect the blood collection area, and formally collect blood after the alcohol volatilizes.
2. Gently press your finger so that the blood can flow out naturally, wipe the first drop of blood with a disinfectant cotton swab, and then drop the second drop of blood onto the test strip area.
3. Avoid pressing your fingers too hard during the process to prevent tissue fluid from mixing into the blood sample, resulting in low blood sugar values.
4 things not to pay attention to, blood sugar is equal to a white test!
1. Pay attention to blood sugar measurement is not "seeking psychological comfort"
In order to seek psychological comfort, some sugar friends may deliberately reduce the amount of food they eat or even not eat before measuring their blood sugar after meals, or take hypoglycemic drugs first and then go for testing, which is meaningless. In order to ensure that the measured blood glucose values have clinical reference value, it is important not to specialize.
2. Pay attention to the "fasting time" of fasting blood sugar
Fasting blood glucose refers to the blood glucose measured in a blood sample taken before breakfast after fasting overnight. Overnight fasting here refers to a period of 8 to 12 hours of fasting, during which it is not advisable to eat anything other than water. If the fasting period is less than 8 hours or more than 12 hours, it cannot be counted as fasting blood glucose in the strict sense.
3. Pay attention to fixing the daily blood collection time
There is a lack of comparability in blood glucose values measured at different time periods, so there must be significant differences between preprandial and postprandial blood glucose. Therefore, in order to facilitate the comparison of changes in blood glucose data, you should try to fix the sampling and measurement values in a fixed time period.
Fourth, pay attention to the operation specifications of blood collection
Collecting a blood sample is a critical step in blood glucose testing, and many patients often have problems with blood glucose that do not meet their blood glucose targets. Therefore, it is especially important to master the correct blood collection procedure.
