“Your sugar is a little high.”
You may have heard this from a doctor or after getting a blood test. But then comes the next question — how high is high? And does one blood sugar reading really tell you what has been happening in your body for the last few months?
This is where the HbA1c test comes in.
Unlike a regular blood sugar test, HbA1c does not just tell you what your sugar level was at the time when your blood sample was taken. It gives an idea about your average blood sugar levels over the last 2 to 3 months.
That is why doctors often suggest this test when they want to check for diabetes, prediabetes or keep an eye on existing diabetes.
What is an HbA1c test?
HbA1c is a blood test that measures the amount of sugar attached to haemoglobin in your red blood cells.
Now, you don’t really need to remember the science behind it. The simple thing to understand is that your red blood cells live for around three months. So, HbA1c gives a bigger picture of your blood sugar instead of showing only one moment.
For example, your blood sugar may be normal on the day you go for a test, but if it has been regularly high during the previous weeks, your HbA1c may still show that.
The test only needs a small blood sample and, in most cases, you don’t need to fast for it.
What is the normal HbA1c range?
When you get your report, you will usually see the HbA1c result written as a percentage.
The general ranges are:
- Below 5.7% – Normal
- 5.7% to 6.4% – Prediabetes
- 6.5% or above – Diabetes range
So, if your report says 5.4%, it is generally considered within the normal range. If it says 6.0%, it falls into the prediabetes range.
And if the result is 6.5% or higher, it may indicate diabetes.
But don’t immediately start worrying after seeing a high number on your report. A diagnosis is not usually made by looking at one number alone. Your doctor may ask for another test or look at your symptoms and medical history before confirming anything.
HbA1c vs normal blood sugar test – what’s the difference?
This is one of the most common doubts people have.
A regular blood sugar test tells you your glucose level at a particular point in time. For example, a fasting blood sugar test checks your sugar after you haven’t eaten for a certain number of hours.
HbA1c is different.
It gives an estimate of your average blood sugar over the past 2 to 3 months.
Think of it this way:
Blood sugar test = what’s happening around now
HbA1c = what’s been happening over the last few months
Both can be useful, and sometimes a doctor may recommend both depending on what they are trying to find out.
So, if you are looking for a blood sugar test in Siliguri, don’t just choose a test based on the name. Ask which test is suitable for your reason for testing.
Who should get an HbA1c test?
Not everyone needs to get an HbA1c test regularly. But your doctor may suggest it if you have certain symptoms or risk factors.
For example, you may be asked to get tested if you:
- Feel thirsty much more than usual
- Need to urinate frequently
- Feel tired without a clear reason
- Have a family history of diabetes
- Have been told that your blood sugar is higher than normal
- Are overweight
- Have high blood pressure or cholesterol
- Have other risk factors for diabetes
People who already have diabetes may also need HbA1c tests from time to time. It helps the doctor understand how well their blood sugar has been controlled.
How often you need the test depends on your individual condition, so there is no single schedule that works for everyone.
Do you need to fast before HbA1c?
Usually, no.
This is actually one of the convenient things about an HbA1c test. You can generally have it without fasting, and it can be done at different times of the day.
But there is one small thing to keep in mind.
If your doctor has asked you to get HbA1c along with other tests, some of those tests may require fasting. So before going to the lab, check the instructions properly. It will save you from making two trips.
How much does an HbA1c test cost?
The cost of an HbA1c test is not the same everywhere. It can vary depending on the diagnostic centre and whether you are getting the test separately or as part of a health checkup package.
If you are planning to get the test in Siliguri, you can simply call the diagnostic centre beforehand and ask about the current price, sample collection timings and when the report will be available.
Prices can change, so checking before your visit is always better than relying on an old price you found online.
What if your HbA1c is high?
First thing — don’t panic.
A high HbA1c means your blood sugar has been higher than the desired range over a period of time. But what happens next depends on your result and your overall health.
Your doctor may suggest another blood sugar test, lifestyle changes, medicines or further evaluation depending on the situation.
Also, HbA1c is not perfect for everyone. Certain health conditions, including some types of anaemia and blood disorders, can affect the result. This is another reason why you should not try to interpret the number completely on your own.
Your report gives you information, but your doctor helps you understand what that information means for you.
Where can you get an HbA1c test in Siliguri?
HbA1c testing is available at pathology labs and diagnostic centres across Siliguri.
If you are searching online for the best diagnostic centre in Siliguri, don’t only look at the price. Check whether the centre offers the test you need, has trained professionals, follows proper testing procedures and provides reports within the promised time.
At Regen Healthcare & Diagnostics, patients can get pathology tests and other diagnostic services in Siliguri. You can contact the centre to ask about HbA1c test availability, pricing and report timings before visiting.
A small reminder before you go
Diabetes can sometimes develop without obvious symptoms. You may feel completely fine and still have higher-than-normal blood sugar.
That is why regular testing can be useful, especially if you have risk factors or your doctor has recommended it.
An HbA1c test is a simple test, but it can tell you something important — how your blood sugar has been doing over the past few months, rather than just on one particular day.
And if your result isn’t in the normal range, don’t jump to conclusions after reading things on the internet. Take the report to your doctor, discuss it and find out what you should do next.
Knowing your numbers is a good first step. Understanding them is even more important.
