What’s the Role of HbA1C in the Diagnosis of Diabetes?



Diabetes is a prevalent condition affecting millions of people worldwide. Early diagnosis and effective management are one of the important factors to prevent complications. The HbA1c test diagnoses and helps to manage the diabetes condition.

This blog will take you through every aspect of HbA1c tests so you can effectively control diabetes and manage overall health.

What Is the HbA1C Test?

HbA1C is a blood test that gives the average blood sugar level for a time period of two to three months.

Glucose from food sources fuels your body's cells, while insulin absorbs glucose into these same cellular units. In people with diabetes, inadequate insulin production or cellular resistance leads to hyperglycemia (excessively high blood glucose levels).

Haemoglobin proteins housed in red blood cells bond with circulating glucose molecules; as such, exchanges become more frequent with increasing concentrations of these sugars within our bloodstream; this leads to an increased sugar coating on haemoglobin until the lifespan of these red blood cell units ends.

On average, a red blood cell resides actively within the body for three months before completing its lifecycle.

Why Is HbA1c Important?

The HbA1c test is essential for the following:

  • Diagnose diabetes and pre-diabetes, allowing for early intervention and management.
  • Examine blood sugar levels in people with diabetes, guiding treatment decisions and preventing complications.
  • Determine individuals at risk of getting diabetes and helps to put preventative measures in place.
  • Routine check-ups for adults over 45 years old
  • Screening for gestational diabetes

Who Should Take the Haemoglobin A1c Test?

The test identifies the amount of glycated haemoglobin. A regular HbA1c blood test is advised if you have had a diabetes diagnosis.

An HbA1c test is advised if you are under the age of 45 when,

  • The test must be done after three years if the findings are normal.
  • The test must be done every one to two years if the results indicate prediabetic.
  • Advised at least twice a year if the findings indicate the patient has diabetes.

It is advised to have an HbA1c test if you are over 45.

  • Whenever type 2 diabetes runs in the family
  • Lack of exercise is a factor in obese patients.
  • If a history of heart disease or a stroke exists.
  • Have high cholesterol or blood pressure.
  • Have PCOS, gestational diabetes, or pre-diabetes.

The HbA1c test is also advised if you have diabetic symptoms, such as

  • increased appetite, thirst, and urine frequency
  • Unexpected weight loss
  • Sores that heal slow
  • Having more infections than usual
  • Blurred vision
  • Dry skin
  • Excess fatigue
  • Numbing and tingling of hands and feet

How Is the HbA1C Test Performed?

The HbA1C test is done anytime and requires no prior preparation or fasting.

A blood sample is collected from a vein in your arm and sent for testing to a laboratory. No risks are associated; you can experience slight bruising or pain when the needle is inserted.

Understanding HbA1C Test Results: Normal, Pre-diabetic, and Diabetic

The HbA1C test results determine whether or not you have diabetes or are at possibility of having it. Here's how to analyse your results:

  • Normal: HbA1C level is below 5.7%
  • Pre-diabetes: A level between 5.7% and 6.4%
  • DiabetesL A level of 6.5% or higher

What Are the Factors Affecting HbA1C Levels?

Several factors fluctuate HbA1C levels, including:

  • Stress
  • Lack of vitamins or supplements in your diet
  • Lack of sleep
  • Anaemia or acute blood loss

It takes around 3-4 months for HbA1C levels to change gradually.

What Are the Symptoms That Indicate High HbA1C Levels?

The symptoms of HBA1c include:

  • Fatigue
  • Weight loss
  • Increased thirst
  • Blurred vision
  • Slow healing wounds
  • Frequent urination

If you feel any of the above, consult your doctor for an HbA1C test and a suitable treatment plan.
