I am trying to understand the relationship of a "high risk of diabetes" A1c and Blood Glucose Level as it concerns the primary diagnosis of diabetes.
The scenario is a 72 y/o slightly overweight female that receives a consult at an urgent care clinic. Her chief complaint is "just haven't been feeling very good". Patient request blood testing.
Physical examination is negative. Her BGL is 105 mg/dl and her A1c is 6.2 %.
My questions are these:
1. Is the A1c only relevant in the diagnosis of diabetes because her BGL is over the threshold of 100 mg/dl?
2. If she lowered her blood glucose through diet and exercise would the A1c become less relevant or is an A1c of 6.2% have a free standing relevance?
3. Should the patient modify diet and exercise and have the test performed again after she seeks a consult with an internist?
