Many glucose patients often need to perform self blood glucose testing (fingertip glucose) to assess the efficacy of their medication (including insulin injections). However, in the clinic, we find that there are people who never test their blood glucose; there are people who test their blood glucose every day; there are people who regularly test their fasting blood glucose in the morning; and there are people who do not know which points of blood glucose should be tested. In this article, we try to provide some basic and applicable blood glucose testing methods. Based on the relatively fixed amount of diet and exercise, the following methods can be chosen according to your own situation: (1) Multi-point blood glucose monitoring method (for those with large blood glucose fluctuations) (1) Day 1 – monitor blood glucose before breakfast and 2 hours after meal, and do not measure other points. (2) Day 2 – Monitor blood glucose before and 2 hours after Chinese meal, and do not measure at other points. (3) Day 3 – Monitor blood glucose before and 2 hours after dinner, and do not measure at other points. (4) Day 4 – Monitor blood glucose before bedtime (10:30 p.m.), no measurement at other time points. The advantage of this scheme: the blood glucose value of 7 time points in 4 days, it has the same clinical value to the doctor as measuring blood glucose 7 times continuously in 1 day. Moreover, in the long run, there is a significant saving of test paper and a reduction in cost. Therefore, for those who have large blood glucose fluctuations and intend to go to the doctor in the near future, it is recommended to finish the above-mentioned blood glucose monitoring for 4 consecutive days before going to the doctor and bring it to the follow-up appointment to help the doctor adjust the plan for you. (2) Single-point or double-point blood glucose monitoring method (for those with stable blood glucose) You can choose one or two of the seven points to monitor according to the time point of blood glucose fluctuation: (1) For those with good fasting blood glucose in the morning, you can directly monitor the 2-hour blood glucose after meal (also can measure the three meals in a day); (2) For those with high fasting blood glucose in the morning, you can choose to monitor the 2-hour blood glucose after meal and the blood glucose before bedtime in the evening; (3) For those with high fasting blood glucose in the morning, you can choose to monitor the blood glucose in the evening. (3) For those who have hypoglycemic reactions in the early morning, they can monitor the blood sugar before bedtime and blood sugar at 3 am. The advantages of this method: it is more flexible, and the time point of monitoring is chosen according to the actual blood sugar situation, which varies from person to person and from time to time, and there is no fixed pattern. (3) Interval of blood glucose monitoring (1) If the blood glucose is more ideal (6-7mmol/L fasting, 7-8mmol/L 2 hours after meal), it can be measured once a half month or once a month. (2) If the blood sugar is stable (fasting 7-7.5mmol/L, 2 hours after meal 8-10mmol/L), it can be measured once a week or half a month. (3) If blood sugar fluctuates greatly (fasting 8-10mmol/L or above, 2 hours after meal 11mmol/L or above), it should be measured once every two to three days. (4) Monitoring of glycosylated hemoglobin This is the simplest monitoring method to assess the control of diabetes. It is suitable for people with stable blood glucose for a long time. Monitoring interval: once every 3 months. Glycosylated hemoglobin (HbA1c) judgment criteria: (1) HbA1c<6.5% ideal control; (2) HbA1c<7% standard control; (3) 7%
