A normal HbA1c with high glucose readings is common and usually explained by red cell turnover, postprandial spikes averaging out, or assay interference. Here is how to tell which, and what to measure next.
A fasting glucose of 86 mg/dL sits in the middle of the normal range and is not low. The more useful question is how much your fasting glucose moves from day to day, which one draw cannot answer.
A1c and glucose disagree when either your glucose sampling is unrepresentative or your red cell biology and hemoglobin assay distort the glycation measurement. Here is how to separate the two with CGM data, a CBC, an assay method check, and a look at your genome.
A fasting glucose of 106 mg/dL places you just inside the prediabetes range by ADA criteria, but a single number carries more measurement noise than most people assume. Here is how to interpret it, what to measure next, and how to read your own CGM data.
A postprandial reading of 97 mg/dL is a normal, unremarkable value in a person without diabetes. Here is what the number tells you, what it does not, and how to read postprandial glucose properly from CGM or fingerstick data.
