You received your HBA1C blood test results but still need help determining if they fall under the normal range. Read this section to know if your results range between the HBA1C normal range.
What Do HBA1C Test Results Mean?
The A1C test results are reported by healthcare professionals as a percentage. A higher A1C percentage corresponds to a higher average blood sugar level. The results of the diagnosis are normally interpreted as follows:
- Below 5.7% is normal.
- 5.7% to 6.4% are diagnosed with prediabetes.
- 6.5% or higher than that on two separate tests indicates diabetes.
If your A1C level is above the mentioned target, your doctor may recommend you adjust your diabetes treatment plan.
What Is HBA1C Test Normal Range?
The normal HbA1c level varies slightly among different sources but generally falls between 4% and 5.6%.

What Medical Conditions Can Cause High HBA1C Levels?
Elevated HbA1c levels, indicating poor blood sugar control, can be caused by various medical conditions, including:
What Medical Conditions Can Cause Low HBA1C Levels?
Low levels of HbA1c (glycated hemoglobin) typically indicate good blood sugar control and are commonly associated with well-managed diabetes. However, there are a few medical conditions and situations that can cause lower-than-normal HbA1c levels:
- Anemia (iron deficiency anemia, hemolytic anemia)
- Blood transfusion
- Hemoglobinopathies (thalassemia, sickle cell disease)
- Chronic kidney disease
- Chronic liver disease (cirrhosis)
