Hi
@mukeshchavan18 . If I understand your numbers correctly you had an HbA1c of 10.1% (DCCT) which equates to a modern UK figure of 87 (IFCC - mmol/L). This translates to an 'average' blood glucose level of 13.5 mmol/L, or 243 in mg/dl.
HbA1c is rightly called an average but it's more rightly called a 'weighted' average. Glycated blood cells can last on average up to 3 months, so an HbA1c measures those glycated cells from (approximately) the last 3 months. The 'weighting' applied to these results use readings from the last 30 days to make up 50% of your HbA1c, fewer readings from 30 - 60 days, even fewer from 60 -90 days.

Let's *** imagine *** the weighting is 50/30/20 and your average blood sugar levels have been
0-30 days 240 mg/dl x 50% = 120
30-60 days 240 mg/dl x 30% = 72
60-90 days 240 mg/dl x 20% = 48
120 + 72 + 48 = 240 mg/dl giving an HbA1c of 86 (IFCC) or 10% (DCCT)
If when you next take your HbA1c a month later your levels have been
0-30 days 120 mg/dl x 50% = 60
30-60 days 240 mg/dl x 30% = 72
60-90 days 240 mg/dl x 20% = 48
60+72+48 = 180
This gives an HbA1c of 63 (IFCC) or 7.9%
When you've had levels at 120 mg/dl for three months, such an average gives an HbA1c of 46 (IFCC) or 63%
So yes, your HbA1c will show a reduction. Keep doing what you're doing.
What medicine are you on ?
