Blood Glucose Monitoring System

Blood glucose monitoring system is the basic means for diabetic to manage diabetes, and blood glucose meter value is an important basis for doctors to judge the condition and adjust plans. Inaccurate blood glucose measurement will directly affect the control of diabetes. In daily life, diabetic may encounter various pitfalls when measuring blood glucose Let’s take stock together today.
Blood glucose standard value
The blood glucose value obtained from the hospital’s biochemical examination should be considered as the standard value. Therefore, to determine the accuracy of one’s blood glucose meter, it is necessary to compare it with the hospital’s data before and after to determine the results of blood glucose values.
Blood glucose measurement data from hospitals
Usually measured in the hospital is one’s own venous blood, which is the glucose content in the serum. Venous blood has strict procedures and quality control standards. If you want to check the accuracy of your own blood glucose meter, you should use the venous blood glucose as the standard.
Blood glucose data measured by a blood glucose test
The blood glucose test detects capillary blood glucose. It is the peripheral blood of the extremities, which contains a mixture of small arteries, capillaries, and veins, as well as interstitial fluid. The blood glucose test you purchased is produced by a legitimate manufacturer and is within the national standard range, so you can use it with confidence.
What situation can lead to inaccurate self-test blood glucose?
Improper use of disinfectants: diabetic do not have alcohol at home, and when they see iodine, they use iodine to disinfect and use it. They find that the measured blood glucose is significantly different from usual.
Disinfect with 75% alcohol, do not use iodophor or iodine containing disinfectant, as iodine has a strong oxidizing effect that affects measurement accuracy.
Blood collection before the fingers are dry after disinfection: diabetic are impatient, and blood collection is carried out before the alcohol is dry after finger disinfection, resulting in alcohol mixing into the blood sample and inaccurate blood glucose levels.
After disinfecting your fingers with alcohol, you should wait for the alcohol to evaporate and dry, or wipe the alcohol clean with a cotton swab, and wait for 10 seconds before taking blood.
Insufficient battery power of the blood glucose meter: After using the blood glucose meter for a period of time, the display screen displays the words “low battery” during testing, which can also cause inaccurate blood glucose monitoring.
The blood glucose meter has not been cleaned and maintained: there is dust, fiber, debris, etc. in the detection area of the blood glucose meter. The correct method should be to clean it with a cotton swab dipped in water.
TIPS: Organic solvents cannot be used to clean the testing area of the blood glucose meter; Do not allow water to seep into the blood glucose meter; Blood glucose meters should not be placed near magnetic field areas for a long time (such as mobile phones, induction cookers, etc.)
The method of collecting blood samples is not accurate: When collecting blood samples, if the blood collection volume is insufficient or the blood droplets are too large to overflow the measurement area, it may affect the measurement results.TIPS: Choose a clean and dry platform, and prepare all necessary supplies; Clean and dry your hands, hang your arms down; Select the needle area on both sides of the finger abdomen that cannot be squeezed
Proper storage of test strips can effectively prevent their deterioration: avoid dampness, place them in a dry, cool, and dark place, and store them tightly after use; The test strips should be stored in the original box and not in other containers; Before measuring blood glucose, it is also necessary to pay attention to checking the effectiveness of the test strip packaging box
To determine the accuracy of blood glucose measurement: You can take your blood glucose meter to the hospital and before taking venous blood, prick your fingertip blood and immediately take the venous blood. By comparison, we can determine the difference in numerical values.
