HbA1c Normal Range in Singapore: What Your Result Means and How to Lower It

In Singapore, pre-diabetes is diagnosed with fasting glucose and the OGTT rather than HbA1c (ACE), HealthHub’s target for people with diabetes is 7% or lower, and Immority EvenOn is built around the 90 days one HbA1c cycle takes.

HbA1c sums up about three months of blood sugar in one number (HealthHub), so it is natural to want to know where yours sits. The catch is that you will meet three sets of numbers: the bands websites quote, the tests Singapore uses to diagnose pre-diabetes, and the target your doctor gives you if you already have diabetes. This guide untangles all three, then shows how to bring a high HbA1c down over the next 90 days.

What is HbA1c?

HbA1c measures how much of the haemoglobin in your red blood cells has sugar bound to it, and it shows your average blood sugar over about the past three months (HealthHub). Glucose binds to haemoglobin for good, so the higher your sugar has run, the higher the number; the EvenOn flyer calls HbA1c the gold standard for judging long-term sugar control. Red blood cells live about 120 days, which is why the result reflects roughly the last 2 to 3 months rather than this morning. The test is done at the clinic, at a polyclinic or with your GP.

What is the normal HbA1c range?

Below 5.7% is normal in the bands you see online, which come from the American Diabetes Association:

• Normal: below 5.7%; American Diabetes Association
• Prediabetes: 5.7% to 6.4%; American Diabetes Association
• Diabetes: 6.5% or higher; American Diabetes Association

Singapore works differently at the pre-diabetes stage: it diagnoses pre-diabetes with fasting glucose and the OGTT, not HbA1c. Singapore’s ACE Clinical Guideline on pre-diabetes (Ministry of Health) says HbA1c is not currently indicated as a diagnostic test for pre-diabetes, though HbA1c may be used to screen for diabetes (MOH Circular No. 08/2019). So an HbA1c of 6.0% is a reason to ask your doctor about a fasting glucose test or an OGTT, not a diagnosis on its own. Our type 2 diabetes guide lists the fasting and OGTT ranges.

What HbA1c target does Singapore use?

For people with diabetes, HealthHub’s target is an HbA1c of 7% or lower, shown in three bands:

• 7% or lower: on target; HealthHub
• 7.1% to 8.0%: above the 7% target; HealthHub
• 8.1% or higher: further above the target; HealthHub

HealthHub adds that you should speak to your care team, as your targets may vary; the number on your own plan is the one to aim for. Why push for every point? In a long-term study of people with type 2 diabetes (UKPDS 35, Stratton et al., BMJ, 2000), each 1% lower HbA1c was associated with 37% fewer microvascular complications (eyes, kidneys, nerves), 21% fewer diabetes-related deaths and 43% fewer amputations or deaths from peripheral vascular disease. That is an association seen over years, not the result of any product.

What does your HbA1c mean as average blood sugar?

Each HbA1c level matches an estimated average glucose, roughly what your blood sugar has averaged over those months (ADAG study, Nathan et al., 2008):

• 5%: 5.4 mmol/L (97 mg/dL); ADAG
• 6%: 7.0 mmol/L (126 mg/dL); ADAG
• 7%: 8.6 mmol/L (154 mg/dL); ADAG
• 8%: 10.2 mmol/L (183 mg/dL); ADAG
• 9%: 11.8 mmol/L (212 mg/dL); ADAG
• 10%: 13.4 mmol/L (240 mg/dL); ADAG

So HealthHub’s 7% target means an average of about 8.6 mmol/L across day and night, meals included. Singapore’s guideline uses mmol/L; if a meter or website uses mg/dL, multiply mmol/L by 18.

How can you lower your HbA1c in 90 days?

Bring down both your fasting and your after-meal sugar, steadily, for about three months, and HbA1c follows. The steps with Singapore’s backing:

1. Change the plate: half vegetables and a small portion of fruit, a quarter lean protein and a quarter whole grains such as brown rice (ACE). At the cai fan stall, that means two vegetables, one protein and less white rice.
2. Swap the drink: water instead of sugar-sweetened drinks (ACE). If you need your kopi or teh, go siew dai, then kosong.
3. Move most days: at least 150 minutes of moderate exercise such as brisk walking a week, or 75 minutes vigorous, with no more than two days in a row off (ACE). A walk after dinner counts.
4. Lose a little weight if you carry extra: for Asians, a BMI of 23 or more means increased risk, and losing 5% to 10% of your weight can help lower blood sugar (HealthHub).
5. Sleep well and keep your medicine: if you are on medicine, take it exactly as prescribed.

If sweet cravings keep undoing the plan, our guide to stopping sugar cravings has practical steps.

Where does EvenOn fit if your HbA1c is high?

EvenOn fits as a daily step with your main meal, alongside the plate, the walking and any medicine you take.

Immority EvenOn is a blood sugar balance drink from Immority. One 5 g sachet a day, stirred into water with your main meal, gives you 11 botanicals led by gymnema (25% gymnemic acid) and mulberry leaf (5% DNJ). It is halal (JAKIM) and classified as a food product by Malaysia’s NPRA, where it is made.

Steadier fasting and after-meal sugar can bring HbA1c down after about three months, and EvenOn’s plan is built around that cycle: days 61 to 90 complete one red blood cell cycle, when HbA1c shows the long-term change. The ingredient studies point the same way, though none tested EvenOn itself. In a 90-day human study of gymnema extract in people with type 2 diabetes (Kumar et al., 2010), HbA1c fell from 9.6% to 8.6%, with after-meal sugar 22% lower. Meta-analyses of 23 human trials of mulberry leaf (Kesharwani et al., 2026) and of 8 trials of bitter melon (Zhang et al., 2024) found fasting sugar, after-meal sugar and HbA1c improved. Your result also depends on your overall sugar control, diet and lifestyle. See how to take EvenOn for the sachet, the meal and the 90-day plan, and what Immority EvenOn is for the full formula.

On diabetes medicine? Keep taking it exactly as prescribed and never stop or change a dose on your own. Check your sugar more often in the first weeks, because readings may come down; people on insulin or gliclazide are the most at risk of going too low. The signs are shaking, sweating, a fast heartbeat, hunger and confusion. Below 4 mmol/L, follow the low-sugar plan your care team gave you, see your doctor if lows keep coming back (HealthHub), and tell your doctor you take EvenOn.

Frequently asked questions

Is an HbA1c of 6% normal? In the American Diabetes Association bands, 6% sits in the prediabetes range (5.7% to 6.4%) and matches an average glucose of about 7.0 mmol/L (ADAG). In Singapore, pre-diabetes is confirmed with fasting glucose or an OGTT, so ask your doctor about those tests.

Is HbA1c used to diagnose pre-diabetes in Singapore? No. Singapore’s ACE guideline says HbA1c is not currently indicated as a diagnostic test for pre-diabetes; it may be used to screen for diabetes (MOH Circular No. 08/2019).

How often should I check my HbA1c? Your care team sets the schedule. Because HbA1c reflects about the past three months (HealthHub), a retest much sooner than that shows little.

What if my HbA1c comes down while I am on medicine? Keep taking your medicine exactly as prescribed and let your doctor review the result. Only your doctor changes a prescription.
