Diabetes testing and understanding A1C levels explained
The A1C test, also known as the hemoglobin A1C, glycated hemoglobin, or glycohemoglobin test, plays a crucial role in diagnosing prediabetes, type 1 or type 2 diabetes, and monitoring blood glucose levels in people with diagnosed diabetes.
For individuals without diabetes, a normal A1C level is less than 5.7%. In contrast, for those with diabetes, the general target A1C level is below 7%, although some guidelines recommend goals as low as 6.5% for tighter control. These targets may vary based on age, overall health, and risk of hypoglycemia.
For children between the ages of 6 and 12, the target A1C levels vary by age group: toddlers (7–9%), school-age children (under 8%), and adolescents (under 7%). Older adults or those with health issues may have relaxed targets (e.g., <7-8%) to balance benefits and risks.
Maintaining A1C levels within these ranges reduces the risk of long-term damage to nerves, kidneys, eyes, and the cardiovascular system. However, it's essential to note that the target ranges are individualized, considering factors such as age, duration of diabetes, comorbid conditions, and risk of hypoglycemia.
An A1C reading of over 5.7% may indicate prediabetes or diabetes. If a person is concerned about their A1C levels or treatment plan, they should consult their doctor. A person can work with their doctor to reassess and adjust their A1C targets over time as their condition and treatment goals may change.
The A1C test measures a person's average blood glucose levels over the past 2 to 3 months, providing a more accurate long-term average, considering fluctuations throughout the day. After diagnosing diabetes, a doctor determines how often to test A1C levels. If a person meets their treatment goals, they may need an A1C test twice a year. When managing blood glucose levels is challenging, a person needs this test more frequently.
To screen for diabetes, a doctor may order an A1C test for someone over 45 years or for younger people who have other risk factors. Symptoms of high blood glucose levels include fatigue, unusual thirst, frequent urination, and blurred vision. Symptoms of low blood glucose levels include nervousness, irritability, confusion, dizziness, hunger, shaking, and sweating.
In healthy populations, defined age-related A1C percentage levels are as follows:
- Younger adults: less than 5.2%
- Adults: less than 5.7%
- Older adults: less than 6.1%
It's crucial to remember that the A1C test measures the percentage of red blood cells with glucose-coated hemoglobin. If you have any questions or concerns about your A1C levels or diabetes management, please consult your doctor.
- For those without diabetes, an A1C level under 5.7% is considered normal, while an A1C reading of over 5.7% may indicate prediabetes or diabetes.
- In people with diabetes, the general target A1C level is below 7%, although some guidelines recommend goals as low as 6.5% for tighter control.
- Maintaining A1C levels within these ranges reduces the risk of long-term damage to nerves, kidneys, eyes, and the cardiovascular system.
- Target A1C levels for children between the ages of 6 and 12 vary by age group: toddlers (7–9%), school-age children (under 8%), and adolescents (under 7%).
- Older adults or those with health issues may have relaxed targets (e.g., <7-8%) to balance benefits and risks.

- For screening diabetes, a doctor may order an A1C test for someone over 45 years or for younger people who have other risk factors.
- Symptoms of high blood glucose levels include fatigue, unusual thirst, frequent urination, and blurred vision.
- Symptoms of low blood glucose levels include nervousness, irritability, confusion, dizziness, hunger, shaking, and sweating.
- In healthy populations, defined age-related A1C percentage levels are: younger adults (less than 5.2%), adults (less than 5.7%), and older adults (less than 6.1%).
- Besides providing valuable insights for diabetes management, the A1C test is relevant to the larger context of health and wellness, as managing multiple medical conditions such as COPD, hyperglycemia, ulcerative colitis, macular degeneration, diabetes, prediabetes, degradation of sclerosis, psoriasis, and other health-related issues often involves maintaining blood glucose levels. This necessitates a holistic approach considering factors such as fitness and exercise, nutrition, and predictive science to ensure an individual's overall health and well-being.
