my fasting glucose level 109, pp 139, hba1c range 9.4, i am not taking any medicine as of now, do i require medication

There is big gap regarding declaring a person as Pre-Diabetic and Diabetic based on 1] Fasting and PP sugar levels 2) HbA1c levels. Many patients with with Fasting sugar less than 100 mg/dl and PP sugar less than 140 mg/dl show HbA1c level in the range of 6 % 0r 6.1 %. A person with Fasting sugar less than 100 mg/dl and PP sugar less than 140 mg/dl is considered Non Diabetic. On the other hand a person with HbA1c level between 5.7 % to 6.4 % is considered as Pre-diabetic. Two comments posted below on this website also confirm this discrepancy. For example Comment posted on 12/16/2013 [yesterday) showing Fasting and PP level as 109 and 139 ( only Pre-Diabetic range) but HbA1c as 9.4 which is very high and is severe Diabetic range. Similarly comment posted on 08/06/2012 stating that blood sugar fasting in last 6 months was 100 and 91 and pp as 122 and 102 Recently I did Hb1ac test and it gave 6.1. On the basis Fasting and PP levels the person would be non -Diabetic. in Reply just below that comment Dr Marks has declared the person as Pre-diabetic. SC Gupta

HbA1c Test can be a good measurement for diabetes, however genetic variations play important role in Diabetes. For example, genetic polymorphisms and mutations have been linked with Maturity onset of diabetes of young (MODY). There are about 15 genes associated with MODY, which were, till-date wrongly diagnosed as Type-1 diabetes. MODY donot require any medicines. Gene therapy and dietary changes alone can cure MODY diabetes. In patients diagnosed with type-2 diabetes, a genetic testing is recommended to find the best treatment for diabetes according to their genetic make-up. Certain dietary and life-style changes can even cure the disbetes completely in some individuals, but others may not be cured at-all from type-2 diabetes. Hence it is now recommended for comprehensive genetic testing for all patients with type-2 diabetes and MODY-type diabetes...
