Brief Answer: Fasting blood glucose, lifestyle, HBA1c in 3 month Detailed Answer: Hi and thanks for the query, HBA1c is a very good measure to follow up how blood glucose over a period of about three months is evolving. There are few components I would love to mention with respect generally to the interpretation of laboratory results. It is important to know if the HbA1c measurement was carried out in the same laboratory or not. I really do not think being at 43 instead of 40, should so much cause any panic. It should however be remembered the actual limits for normal measures, eg, 20 - 40 for HBA1c are usually averages and there are always persons that are normal, but out of these limits. I would strongly suggest you get also done, a simple fasting blood sugar. This shall help in confronting the results of the HBA1c and give a good idea of how your blood sugar is evolving. It is interesting the you have adopted already a very healthy lifestyle, first, being a keen watch over your health, secondly losing weight with a good BMI. These practices, coupled with exercise, healthy diet, low salt diet, less saturated fats should be continued. I do think its time to really bother much. I suggest you get a fasting blood sugar done, and do another HBA1c measurement, preferable in the same laboratory under fairly similar conditions within three months, while maintaining a healthy life style. Thanks and kind regards as I wish you the best of health. Dr Bain
