Sir, I recently had a fasting glucose test, which showed 103 mg/dL, and an HbA1c test, which showed 12.52 percent. Is it possible for these results to be correct together, or is there a mismatch?

FBS 103 is pre diabetes range. HbA1c 12.5 percent is uncontrolled diabetes. Mismatch suggests long term high sugars. Repeat HbA1c, do PPBS. Consult doctor for treatment.

Take a HbA1c Test (Hemoglobin A1c) Test or Take a PPBS Test (Post-Prandial Blood Sugar) Test

I am a 47 year old diabetic with neuropathy. My last clinical test showed an HbA1c of 5.9 percent and creatinine of 0.9 mg/dL. At that time, I was taking Metformin 500 mg twice daily, Novomix 30 (18 units before breakfast and 12 units before dinner), and Lantus 20 units at bedtime. Later, my doctor advised Novomix 30 (18 units before breakfast, 12 units before dinner), Lantus 18 units at bedtime, and Transpire M30 after breakfast. My recent report shows that my HbA1c has risen to 7.5 percent, creatinine to 1 mg/dL, and fasting sugar from 84 to 144 mg/dL. I would like advice on whether I should continue the doctor latest prescription or switch back to my previous regimen.
