Most noninvasive blood glucose meters are not very accurate. At present, it is found that the accuracy of venous blood glucose measurement is higher than that of instrument measurement, and the accuracy of instrument measurement is higher than that of non-invasive blood glucose meter, so the accuracy of non-invasive blood glucose meter needs to be improved.

If you really want to know your blood sugar, you should look for the most accurate blood sugar monitoring method regularly, detect fasting blood sugar, two-hour blood sugar after meals and glycosylated hemoglobin for comprehensive analysis, so as to objectively reflect the real situation of blood sugar. As a diabetic, it is very important that the determination of blood glucose meter is accurate and can give doctors more accurate information. Therefore, at present, the determination of noninvasive blood glucose meter is mostly inaccurate. It is necessary to go to a regular hospital to evaluate the efficacy of blood sugar and hypoglycemic drugs with peripheral blood sugar and glycosylated hemoglobin measured by intravenous blood or fingers, and whether it is necessary to adjust the medication plan.

Blood sugar measurement method

Monitoring blood sugar mainly includes venous blood sampling and peripheral blood sampling. It is necessary to do glucose tolerance test to determine whether there is diabetes, draw blood once on an empty stomach, and draw blood once every kloc-0/hour, 2 hours and 3 hours after taking 75 grams of glucose orally, and determine whether there is diabetes according to insulin and blood sugar values. You can also draw blood to check glycosylated hemoglobin, judge the blood sugar value in the past three months, and judge whether there is abnormal blood sugar.
