Hba1c is your average blood glucose (sugar) levels for the last two to three months. if you have diabetes, an ideal hba1c level is 48mmol/mol (6.5%) or below. if you’re at risk of developing type 2 diabetes, your target hba1c level should be below 42mmol/mol (6%)..
The formula for converting a1c to an estimated average blood glucose level, reports the american diabetes association, is (28.7 x a1c) – 46.7 = estimated average glucose. thus, the first step for performing the reverse calculation is to add 46.7 to your average blood glucose..to convert an a1c to the new average mean blood glucose, use this formula: eag(mg/dl) = (28.7 x hba1c) – 46.7 so.
