Random blood glucose high but hba1c normal: When you get your blood test done and the level of HBA1C comes less than 6 in the Ulke Results, you are indicative that you have no danger of databetas. But at the same time, when saw the report of random blood glucose (RGB), its result came out. The question arises from here that when HBA1C is normal, then why did the sugar come out. Is this a sign of diabetes. For this, it has to be understood why RGB report is not normal when Akhir HBA1C is normal?
HBA1C called glycated hemoglobin is the last 2 to 3 months report card of your blood sugar. It tells how your sugar level was an average in these months. If HBA1C – is less than 6, it means that your sugar has been normal most of the time. But keep in mind, it is average, then it can hide it in between.
What is RBG
RBG (Random Blood Glucose) is the immediate sugar check at that time. There is no fasting or time ban on time. If you had eaten sweet or more carbas before the test or were in stress, were sick or had taken any medicine, then RBG could come more at that time. Even if your HBA1C is normal.
Normal: 5.6% or less
Pre-diabetes: 5.7% to 6.4%
Diabetes: 6.5% or more
Why does RGB high come despite HBA1C being correct?
According to Dr. Ajay Kumar in Delhi MCD, Many times the situation is vomited. RGB high may come despite HBA1C being correct. This happens when your blood sugar level is normal but sometimes it increases suddenly. This can happen when you have taken too much sugar on that day and have not taken protein, but if these spikes are happening again and again, it is not good for the body, because suddenly increasing sugar level can damage blood vessels and nerves.
RBG can increase in the investigation after eating sweet
Many times, timing changes in blood sugar test. Suppose you have eaten sweet half an hour before the test, then the high coming of RBG (random blood glucose) is almost sure. But this does not mean that you have diabetes. It may also happen that on the day of Test, you are sick, there is an infection, more stress. In these conditions, some hormones change in the body, which increases the sugar level. That is, it is not right to find out the result by looking at the high report of one time.
Check again if needed
But, if your RBG is repeatedly coming to 200 mg/dl or above, whether HBA1C (the average sugar of the last 23 months) is normal, then the doctor will definitely ask to get further investigations. Maybe you have a prevention or impaired glucose tolerance. Meaning your body is unable to control sugar properly. But the initial stage is currently visible in HBA1C. In such a situation, doctors often get OGTT (glucose tolerance test) or fasting blood sugar test, so that it can be clearly known whether there are diabetes or not.
Then what should be done?
Regarding this, Dr. Ajay says if HBA1C is normal but if RBG has come, then there is no need to panic. But do not take it lightly. Check blood sugar at different times a few days-sometimes empty stomach, sometimes 2 hours after eating. This will reveal a pattern. If the reading high is found again and again, see the doctor. Also improve your diet and lifestyle. Avoid eating sweet and more carb, take food with more fiber, do light exercise daily and try to reduce stress.
