A1c- Hemoglobin (Hgb)
The A1c test works by measuring the hemoglobin A1c level. Hemoglobin is stored in the red blood cells. When glucose levels are high, the sugar starts to combine with the hemoglobin. It takes the body 8 to 12 weeks to bring hemoglobin A1c levels back to normal. Therefore, if hemoglobin A1c levels are high, that means that there has been a high level of glucose in the blood over the last 2 to 3 months.
A1c Test: Everything You Need to Know
Did you know that everything you eat on a daily basis will eventually turn into glucose in the body? Whether you eat lettuce, a big steak, or some chocolate, the human body turns these foods into glucose in the bloodstream.
You can think of glucose as the fuel of humans. It's necessary for healthy living, but it shouldn't be too much as high glucose levels can cause problems. For example, diabetes is one of the most common health problems associated with high blood sugar levels.
What Is A1c and the A1c Test?
A1c is also known as glycated hemoglobin. Some red blood cells have hemoglobin with glucose attached to it. This forms A1c and its quantity is expressed as a percentage.
A1c is important because it can show you a snapshot of your glucose levels in the last 3 months (the approximate lifespan of red blood cells). Measuring the A1c will let you know if there have been major spikes in glucose levels in your bloodstream lately. The A1c blood test can be done easily using just a single blood sample.
Who Should Do the A1c Test?
The A1c test kit should be done by everyone at least twice a year, particularly those who eat a high quantity of processed sugar every day. The American Diabetes Association uses the A1c blood test to determine if a person is at risk of developing diabetes. The test can also be used to monitor the glucose levels of those who already have diabetes and see if treatment is working.
What Are the Normal Levels of A1c?
As mentioned earlier, A1c is expressed as a percentage. If its levels get too high, health complications might appear. Ideally, the A1c should be maintained under 6%-7%, but remember that this number fluctuates depending on your diet and moment of the day.
Here is some basic information on normal A1c levels:
- 5% A1c correlates with an average glucose level of 97 mg/dL
- 6% A1c correlates with an average glucose level of 126 mg/dL
- 7% A1c correlates with an average glucose level of 154mg/dL
- 8% A1c correlates with an average glucose level of 183mg/dL
- 9% A1c correlates with an average glucose level of 212mg/dL
Remember that the A1c measures the glucose levels over the last 3 months. Blood sugar levels should remain relatively low and steady if you want to prevent the risk of developing diabetes in the future.
If you get a high A1c reading, it means that your glucose levels have been consistently high in the past three months. This test is different from a standard glucose test where the doctor pricks your finger for a drop of blood to measure your current glucose levels.
Based on the results you get from an A1c test, your doctor can determine if you have healthy glucose levels or you're about to develop diabetes in the future if you don't change your eating habits. For example:
- A1c below 5.7% is non-diabetes
- A1c between5.7% and 6.4% is pre-diabetes
- A1c over 6.4% usually means that you have diabetes type 1 or 2
What Are the Complications That Can Arise from a High A1c Reading?
As you probably already know, diabetes is a dangerous disease with multiple complications. You will need a special diet for the rest of your life and you are exposed to different health risks. Testing your A1c levels and making appropriate lifestyle changes can prevent diabetes from deteriorating your health.
It also means that you can prevent additional health complications that are usually associated with high A1c values. For example, you can prevent having to live with high blood pressure and blurry vision. Monitoring your A1c levels can also prevent stroke, nerve damage, cardiovascular problems, and heart failure.
That's why it's important to do the A1c blood test a few times per year. The test is affordable, it can be bought online, and you can get the results back in just a few days.
Is the A1c Test Kit Enough to Confirm a Diabetes Diagnosis?
In most cases, yes. However, there are other glucose tests out there that can help doctors give an even more accurate diagnosis. For example, fasting insulin test looks at the level of insulin in your body.
Once glucose gets into the bloodstream, the pancreas is instructed to produce insulin. This substance unlocks the body cells to absorb the glucose in the bloodstream. This gives you energy. When your body secretes too little insulin, you can have a high glucose level in the blood which might lead to diabetes.
When too much insulin is secreted, this can lead to hypoglycemia, a condition in which you have too little glucose in the bloodstream. Maintaining a good balance between glucose and insulin is key. The fasting insulin blood test checks that for you. Some people with insulin resistance also have high insulin.
If you want to take a broader look at your health, you can do that with the Comprehensive Metabolic Panel. This panel of tests can check the level of glucose in your body as well as other substances and proteins that might contribute to poor health.
Some of the substances checked by the CMP include electrolytes, calcium, protein, creatinine, and others.
Another glucose test is the two-hour glucose tolerance test. This checks how well your body processes glucose and how quickly. In healthy individuals, the insulin levels will raise when glucose is detected in the bloodstream. Once the blood sugar gets into the cells, the insulin levels drop and everything comes back to normal.
The test is done by giving patients a sweet drink. The doctor checks how quickly the glucose is processed by the body. The test usually takes two hours and if it takes a long time for the glucose levels to get back to normal, the patient in question might be predisposed to diabetes.
How Is the A1c Blood Test Performed?
Glucose levels can be easily determined using a single blood sample. You visit websites such as DiscountedLabs to order your A1c hemoglobin test at an affordable price. Once your order is confirmed, you are mailed a form that you should print.
Take this form with you to the nearest lab or clinic for drawing a blood sample. Once a blood sample has been taken, it will be analyzed in a few business days. You will get your results by mail and you can compare the A1c levels against reference values such as the ones mentioned in this article.
You can also go to your primary healthcare provider to help you interpret the results. The benefits of ordering the A1c test kit online are multiple. You get your results quickly, the whole process is confidential, and you skip the middleman who in this case is represented by your doctor.
Order Your A1c Test Today!
Remember that knowing your glucose level right now might not be enough. It's best to also take a look at it in the past months and see how your body is processing glucose. The A1c blood test can do exactly that - it gives you a complete snapshot of your glucose levels for the last 90 days. You could also go for an A1c test kit, but these are not as accurate as a direct-to-consumer a1c blood test.
This can be very useful to determine if you have stable glucose levels or you're about to get diabetes soon. Order your A1c test today and find out!
