HbA1c (Hemoglobin A1c) A1c Chart, Test, Levels, & Normal Range

HBA1C Chart

Hemoglobin is a kind of molecule that is present in red blood cells and helps in carrying oxygen to the body’s tissue. Hemoglobin A1c or HbA1c or glycosylated hemoglobin is a form of hemoglobin that contains sugar. Read this blog to know about the hba1c test means, normal range of hba1c chart in detail with cost and and how 1000s of people have been able to achieve normal HbA1c levels through Diabetes Reversal Method

People with diabetes are known to have a higher amount of glycosylated hemoglobin level than non-diabetic people. Therefore, in order to have a control level of blood glucose, HbA1c tests are done.

Need to Monitor HbA1c Level

Blood Glucose levels can fluctuate every minute depending upon your activity and the food you eat. Therefore, it is important to regularly monitor your blood glucose or sugar levels as it helps in understanding how your blood glucose levels are changing and how your meals are affecting it. But a proper diet plan with constant push and motivation can help you regulate your blood glucose levels.

Generally, urine tests and daily prick methods were used to measure sugar levels in people with high blood sugar levels. Although these tests are somewhat accurate but can give false reports at times. HbA1c test is helpful in measuring average blood sugar levels over the past 2-3 months. People with diabetes are required to get this test done regularly so that they can keep a check on their blood sugar levels. This ultimately helps in diabetes management.

Improving lifestyle, i.e sleeping pattern, eating habits(what and how much to eat) and proper fitness guidance is helpful in maintaining healthy blood sugar levels for life. I have seen people reducing their HbAc1 from 9.8 to 5.6 during the Diabetes Reversal Program.

Reasons for Fluctuations in Glycosylated Hemoglobin

Use of Insulin, fasting, oral intake of glucose or frequent fluctuations in your blood sugar levels are the most common reasons for the alteration in glycosylated hemoglobin levels. If people with diabetes notice the fluctuations in their glycosylated Hb level, they should consult doctors to maintain the HbA1c levels at the normal range. This helps in reducing risks and avoiding complications due to diabetes.

Getting rid of Insulin and other medications by proper sleeping, eating and workout habits, sounds impossible. But I have come across many people who have been able to regularise their Glycosylated Haemoglobin Levels and live a healthy life after successful Diabetes Reversal.

The Measure of Glucose in Glycosylated Hemoglobin

In the glycosylated hemoglobin test, the percentage of hemoglobin that is bound to the glucose is measured. The average concentration of blood glucose is reflected in this test after three months. The glycosylated hemoglobin can be measured in percentage or in units of mmol/mol. This is now a standard unit in which glycosylated hemoglobin is measured all over the world.

Know Your Normal Range of HbA1c With Help of Chart

normal range of HbA1c

People can have different normal ranges of HbA1c. Here you can check out with the help of hba1c normal range chart, what should be the normal levels of glycosylated hemoglobin for individuals:

  • In non-diabetic people: Several reports have revealed that the complications of diabetes can be reduced if your HbA1c range is below 7%. A healthy person can have HbA1c measure less than 6% of the total hemoglobin. Below 6.0%, or below 42 mmol/mol is the normal value for a non-diabetic adult.
  • In a pre-diabetic person: If your blood sugar levels are slightly higher than the normal range then you are a pre-diabetic person. Your diabetes levels are not too high to be considered as type-2 diabetes. With a proper lifestyle and diet management, you can control your diabetes at this level by Diabetes Reversal Method and can attain normal HbA1c value is 6.0% to 6.4%, or 42 to 47 mmol/mol.
  • In diabetic people: Any person suffering from type-2 diabetes then your normal value is 6.5% or above, or 48 mmol/mol or above. This range may be normal but there is a need for proper guidance of doctors and medications along with healthy lifestyle change to maintain the range. If your value goes beyond the mentioned range then it can increase the risk of heart stroke, peripheral artery disease, glaucoma, diabetic foot, diabetic kidney disease and more.

Over 10000 pre-diabetic and diabetic people have successfully come from the orange and red zone (dangerous, deadly) to green zone (optimal, super optimal) by making sustainable lifestyle changes. Few people I know, didn’t believe that diabetes reversal is possible or one can be off diabetic and other medications, before they got on a call with us. They believed, worked towards their goal with proper guidance of coaches and are now Diabetes free.

Not all High Values of HbA1c Means You are Diabetic

If you get a high HbA1c level, it does not necessarily mean that you are suffering from high diabetes. A lot of people are there who have a variant form of hemoglobin other than type A. This is known as hemoglobinopathy and can seriously show the high or low values of HbA1c.

If you are anaemic or struggling with iron deficiency in your body then also you are likely to get the wrong values on the average of 3 month diabetes test. Therefore, if you want the average of 3 months blood glucose test done, make sure you are not anaemic.

There are some medications also well which can alter your results of glycosylated hemoglobin test levels. These include:

  • Supplements like Vitamin C or E, iron, vitamin B12 and folate
  • Erythropoietin therapy
  • Aspirin
  • Antiviral and antimicrobial medicines.

If you are going for a glycosylated hemoglobin test, your doctor will make sure of the factors that can affect your test results.

Quantity and quality of food can have a great impact on your haemoglobin levels, which can get you incorrect values. There was a patient who had high level stress of being diabetic because of high HbAc1 level. With stress comes so many other problems like insomnia, fatigue, low energy levels, suicidal thoughts etc. After taking our consultation call and joining the Diabetes Reversal Program, he is now enjoying a healthy lifestyle, which includes nutritious food that is easily available in the kitchen and suits his body, and exercises which can be done at home as well as at the office.

What Causes High or Low Hemoglobin A1c Levels?

The level of Hemoglobin A1c is largely dependent upon the blood sugar levels. The higher the blood glucose (sugar) level, the higher is the amount of hemoglobin A1c. Factors responsible for altering the levels of Hemoglobin A1c include:

  • Oral or intravenous glucose consumption
  • Fasting
  • Insulin usage
  • Combinations of any of above stated factors

How Does A1c work?

A1c testing depends upon hemoglobin. Hemoglobin is present in the person’s RBC and transfers oxygen all through the body. When glucose is present in the blood, it sticks (glycates) to the hemoglobin. Higher amount of glucose in the blood results in more sticking to the hemoglobin. The A1c test assesses the average glucose getting adhered to the hemoglobin over time.

What is A1C and eAG? and What is the Difference?

If a person has Diabetes and is tracking his or her blood sugar levels using a home monitor, then the physician may report A1C results as eAG. Rather than a percentage, the reporting of eAG results is done in milligrams per deciliter (mg/dl) or millimoles per liter (mmol/l) units. For instance, 7% A1c level is equivalent to eAG of 154 mg/dl or 8.6 mmol/l.

Does Low Hemoglobin Affect A1C?

Low hemoglobin has a straightforward relationship with the levels of HbA1c. This means that hemoglobin level drops when hemoglobin levels drop down.

There are so many food items in our kitchen which are full of nutrients but most of us are not aware of those. As I recall, a patient who over the consultation call told us about her not wanting to consume supplements to fulfill her nutrient requirements but was looking for a diet which includes staple food. A personal diet coach helped her with a diet chart, customised according to her body requirements and easy to follow for life.

Hemoglobin A1c Conversion Chart (HbA1c chart)

Till now there is no specific guideline by concerned health organizations for using Hemoglobin A1c test as the tool to screen diabetes. However, HbA1c high values indicate that a person may have diabetes.

The following chart shows the correlation between HbA1c levels and average blood sugar levels.

A1(%) Mean blood sugar (mg/dl)
6 135
7 170
8 205
9 240
10 275
11 310
12 345

Studies have shown that 1% reduction in HbA1c glucose level reduces the risk of microvascular diseases upto 10%. Thus, when you get closer to HbA1c normal level, the absolute risk of microvascular diseases or complications also gets lower.

Benefits of Testing Diabetes with HbA1c Over Other Diabetes Test

There are a number of benefits for which diabetes test using HbA1c is preferred over the other types of diabetes test. Some of the benefits include:

  • No preparations are required: There is no need for preparations beforehand to get the HbA1c test done. It can be done at any time of the day. However, the other diabetes tests require fasting. In such a type of test, a person is required to fast for at least 5-6 hours. After the fasting test for diabetes is done, there is another after meal blood test done to know the levels of your blood sugar post meal.
  • No special diet to follow: An oral glucose tolerance test is another kind of test to diagnose diabetes. In this test a special diet is required to be followed for 3 days before you get your test done. Along with this, you are also supposed to fast overnight before the test. However, while going for HbA1c check, you can eat or drink anything you like.
  • Convenient and time saving: Within a couple of hours multiple blood tests are done to know the blood sugar levels in various other tests to diagnose or check sugar levels. However, HbA1c is a single blood test. You can even get the HbA1c report within 24 hours of the test and the procedure is also simple.

Limitations of Measuring Value of Hemoglobin A1c

Hemoglobin a1c  blood test is not suitable if you need to track your blood sugar level on a regular basis i.e you are highly diabetic.. This is because HbA1c does not get influenced with the fluctuations of blood glucose level. You also cannot diagnose the presence or absence of hypoglycemia or hyperglycemia. You may also get the false high value of HbA1c levels in case of kidney failure, high intake of alcohol, anaemia, thalassemia and sickle cell disease.

Natural Ways to Bring HbA1c Normal

Those who have higher levels of HbA1c can bring down the level of HbA1c to the normal range through medications. Apart from this, there are some natural ways as well which can bring your HbA1c normal. These include:

  • Quit smoking to get hemoglobin A1c levels down.
  • Eat a balanced and healthy diet so that your immune system and hormonal balance is maintained.
  • Exercising is another natural way to control your increased levels of glycosylated hemoglobin. It helps in losing weight and lowering blood sugar which ultimately results in enhancing insulin sensitivity.
  • Adopt a healthy lifestyle to keep your blood sugar levels in control.

All this can be attained without disturbing your daily schedule of personal and professional life. Like Ms. Dheeraj Sabharwal who has been able to reduce her HbA1c level from 9.8 to 6.2 by switching on to a healthy lifestyle with the constant support and motivation of Diet Coach, Fitness Coach along with the Diabetologist. She has successfully reversed diabetes while pursuing her teaching profession and also taking care of the family.
