Diabetes screening Singapore adults frequently delay is one of the most important preventive health steps you can take. According to MOH’s National Population Health Survey 2024, approximately 9.1% of Singapore residents currently live with diabetes — and 1 in 3 Singaporeans faces a lifetime risk of developing the condition. Furthermore, the number of Singaporeans with diabetes is projected to reach one million by 2050 if current trends continue. Yet many cases go undetected for years, because Type 2 diabetes often causes no symptoms in its early stages.

This guide covers who should screen, which tests are involved, what the results mean, and how to act on your findings.

Why Diabetes Screening Matters in Singapore

Singapore declared a national War on Diabetes in 2016. The reason is straightforward: diabetes is not merely a blood sugar condition. Without detection and management, it silently damages blood vessels, nerves, and major organs over many years. Consequently, uncontrolled diabetes leads to complications including kidney disease, vision loss, cardiovascular disease, and nerve damage in the feet.

The challenge, however, is that most people with early-stage Type 2 diabetes feel completely normal. Moreover, pre-diabetes — where blood sugar is elevated but not yet in the diabetic range — causes no symptoms at all. Without diabetes screening Singapore clinicians recommend, many people only discover the condition after complications have already developed.

Who Needs Diabetes Screening?

According to the Health Promotion Board Singapore (hpb.gov.sg), the following groups should prioritise regular diabetes screening:

Screen from age 40 (or earlier if risk factors are present):

All Singaporeans and permanent residents aged 40 and above
Those with a family history of Type 2 diabetes in a first-degree relative (parent or sibling)
Individuals who are overweight or obese (BMI ≥23 kg/m² for Asians)
Women who had gestational diabetes during pregnancy
Those with a history of pre-diabetes on a previous test

Screen earlier (from age 18 to 39) if:

BMI is 27.5 kg/m² or above
You have two or more additional risk factors such as high blood pressure, high cholesterol, a sedentary lifestyle, or a family history of diabetes
You experienced gestational diabetes in a prior pregnancy

Subsidised screening under Healthier SG: Healthier SG (healthiersg.gov.sg) provides eligible Singapore Citizens with subsidised diabetes screening at enrolled Healthier SG clinics. Check your eligibility directly through HealthHub or your enrolled family doctor.

What Diabetes Screening Involves

Diabetes screening Singapore patients undergo at a health screening centre typically includes several blood-based tests. Each test measures a different aspect of blood sugar control.

Fasting Blood Glucose (FBG)

This test measures the level of glucose in your blood after an overnight fast of at least 8 hours. It is the most straightforward and widely used test for initial diabetes screening.

Result	Interpretation
Below 6.0 mmol/L	Normal
6.0 – 6.9 mmol/L	Impaired fasting glucose (pre-diabetes range)
7.0 mmol/L and above	Consistent with diabetes — requires follow-up

A single elevated result alone does not constitute a diagnosis. Your physician will recommend a repeat test or additional testing to confirm.

HbA1c (Glycated Haemoglobin)

HbA1c reflects your average blood sugar level over the past 2 to 3 months. Therefore, it provides a broader picture than a single fasting test alone. It does not require fasting, which makes it convenient to include alongside other blood tests.

HbA1c Result	Interpretation
Below 5.7%	Normal
5.7% – 6.4%	Pre-diabetes range
6.5% and above	Consistent with diabetes — requires follow-up

Fasting Insulin (in selected packages)

Some comprehensive executive packages additionally include fasting insulin levels alongside glucose. This allows your physician to assess insulin resistance — the underlying mechanism in Type 2 diabetes — rather than elevated glucose alone.

Urine Tests (Urine Sugar and Microalbumin)

Urine tests check for the presence of glucose or albumin (a protein) in urine. In an individual with uncontrolled diabetes, glucose spills into the urine when blood sugar is high. Microalbumin in the urine, meanwhile, is an early indicator of diabetic kidney disease. Both markers therefore add useful diagnostic context alongside blood-based tests.

Pre-Diabetes: The Stage Most People Miss

Pre-diabetes is where diabetes screening Singapore clinicians most want to catch patients — because it is still reversible. At this stage, blood sugar levels are higher than normal but have not yet crossed into the diabetic range. Consequently, lifestyle changes to diet, physical activity, and weight management can prevent or significantly delay the progression to full diabetes.

However, pre-diabetes produces no obvious symptoms. Most people with pre-diabetes feel entirely well. Therefore, without a routine blood test, this window of opportunity closes without awareness.

If your screening reveals a pre-diabetes result, your HOP physician will discuss your specific results in context and advise on appropriate next steps. This conversation is one of the most valuable parts of the screening process.

What Happens If Your Result Is Abnormal?

An elevated glucose or HbA1c result at screening does not automatically mean you have diabetes. Moreover, a single result in isolation is rarely sufficient for a clinical diagnosis. Your physician will typically recommend:

A repeat fasting glucose or HbA1c test on a separate day to confirm
Additional tests if other risk factors or symptoms are present
A referral to your regular GP or an endocrinologist for ongoing care and monitoring if diabetes is confirmed

Additionally, many factors can temporarily affect blood glucose — recent illness, significant stress, or certain medications, for example. This is another reason why physician consultation at the time of your screening matters.

The Link Between Diabetes and Other Conditions

Diabetes rarely exists in isolation. According to MOH’s National Population Health Survey 2024 (moh.gov.sg), approximately 1 in 3 Singapore residents also has hypertension, and elevated cholesterol rates remain high. These conditions — diabetes, hypertension, and hyperlipidaemia — frequently occur together and significantly increase cardiovascular risk when combined.

Therefore, a comprehensive health screening is far more informative than a standalone glucose test alone. For this reason, HOP’s screening packages assess diabetes, kidney function, lipid profile, liver health, and other markers together in a single visit. This combination gives a complete picture of metabolic health rather than a partial one.

How Often Should You Screen for Diabetes?

Screening frequency depends on your current results and risk profile:

Situation	Recommended Frequency
Normal results, low risk	Every 3 years from age 40
Normal results, elevated risk factors	Every 1 to 2 years
Pre-diabetes result	Every 6 to 12 months — discuss with your physician
Confirmed diabetes	Ongoing management with your regular doctor

For individuals managing known diabetes, the tests above form part of regular monitoring rather than screening. Your physician or specialist will guide the frequency of ongoing testing.

Diabetes Screening at HOP Medical Centre

Diabetes screening Singapore patients can access at HOP Medical Centre includes fasting blood glucose, HbA1c, urine glucose and albumin, and kidney function markers as part of our Executive Health Screening packages. Additionally, our Express Health Screening packages and affordable health screening packages include core diabetes-related blood tests suitable for annual preventive checks.

For companies that want to incorporate diabetes screening into employee health programmes, our corporate health screening packages include diabetes profiles as standard. Given the high prevalence of diabetes and pre-diabetes among Singapore’s working-age population, early detection at the workplace level directly reduces long-term healthcare costs and absenteeism.

Every screening at HOP includes a physician consultation. Consequently, your results are explained in context — not simply printed on a report. Your doctor will also flag whether your results suggest the need for any follow-up tests or referrals.

Both our Orchard (Palais Renaissance) and Tampines (CPF Building) clinics provide a non-fasting option alongside our fasting packages, so you can choose the format that best fits your schedule.

Check your blood sugar — before symptoms appear.

Diabetes screening is available at HOP Medical Centre Orchard & Tampines, with physician consultation included.
