Hemoglobin (Hb) A1c With eAG Blood Test

What is the purpose of this test?

The Hemoglobin (Hb) A1c With eAG Blood Test is a crucial diagnostic tool for evaluating long-term blood sugar levels and assessing an individual's risk of diabetes and prediabetes. Hemoglobin A1c measures the percentage of glucose (sugar) attached to hemoglobin, the protein in red blood cells that carries oxygen. Since red blood cells have a lifespan of about 90–120 days, this test provides an average of blood sugar levels over the past two to three months, making it more reliable than a single fasting blood glucose test. The estimated average glucose (eAG) component translates the HbA1c result into an approximate daily blood sugar level, making it easier to understand for both patients and healthcare providers.

Doctors commonly use the HbA1c with eAG test to diagnose type 1 and type 2 diabetes, monitor how well diabetes is being managed, and assess whether lifestyle changes or medications are effectively controlling blood sugar levels. Unlike standard glucose tests, this test does not require fasting, making it a convenient and accurate option for evaluating chronic blood sugar control. Higher HbA1c levels indicate poor glucose control, which can increase the risk of heart disease, kidney disease, nerve damage, and vision problems. Regular monitoring with this test can help individuals and healthcare providers prevent complications and adjust treatment plans as needed.

Who should get this test?

• Individuals with a family history of diabetes or prediabetes
• Those experiencing symptoms of high blood sugar, such as excessive thirst, frequent urination, or unexplained fatigue
• People with known diabetes who need routine monitoring of blood sugar control
• Individuals who are overweight or obese, as excess weight is a risk factor for diabetes
• Anyone with high blood pressure or cholesterol, which are linked to insulin resistance
• Pregnant individuals with gestational diabetes or at risk of developing it
• Those with a history of polycystic ovary syndrome (PCOS), which increases the risk of insulin resistance
• People who have experienced unexplained weight loss, blurred vision, or slow-healing wounds
• Anyone looking to assess their overall metabolic health and risk of developing diabetes

When should I order the Hemoglobin (Hb) A1c With eAG Blood Test?

Individuals may consider ordering this test if they have symptoms or concerns related to high blood sugar or diabetes risk.

Symptoms to consider:

• Frequent urination and excessive thirst
• Unexplained fatigue, dizziness, or blurry vision
• Numbness, tingling, or burning sensations in the hands and feet
• Unintentional weight loss or difficulty gaining weight
• Increased hunger despite eating normally
• Slow-healing cuts, wounds, or recurrent infections
• Darkened skin patches, particularly on the neck or armpits (a sign of insulin resistance)

If you have these symptoms or risk factors for diabetes, the Hemoglobin (Hb) A1c With eAG Blood Test can provide valuable insights to help you and your doctor diagnose and manage your health.
