| Hemoglobin A1c (HbA1c) Blood |
<6% of total Hb AACE Guidelines (2011) Hemoglobin A1c, % (as a screening test) ≤5.4 - Normal ------------------------- 5.5-6.4 - High risk/prediabetes; requires screening by glucose criteria ------------------------- ≥6.5 -Diabetes, confirmed by repeating the test on a different day ================= In general, therapy should target a A1C level of 6.5% or less for most nonpregnant adults. |
