HbA1c Test in Ja-Ela: Catching Prediabetes Before It Becomes Diabetes

Quick answer: HbA1c shows your average blood sugar over the past 2–3 months in a single test. It needs no fasting and can be taken at any time of day. At St. Luke's in Ja-Ela it costs LKR 2,100. A fasting blood sugar (LKR 280) shows one moment; HbA1c shows the trend. Broadly, below 5.7% is normal, 5.7–6.4% is prediabetes, and 6.5% or above suggests diabetes — but only your doctor can interpret your result properly, and a diagnosis is not made on one number alone.

The number Western Province should know

Sri Lanka's diabetes burden is not a future problem. It is already here, and it is worse in our province than the national average.

• The national Health and Ageing Survey (2018/19) put diabetes prevalence in Sri Lankan adults at around 23%, with prediabetes at roughly 30% on top of that.
• In the Western Province specifically — Colombo, Gampaha and Kalutara — the age-and-sex standardised diabetes prevalence was measured at 27.8%.
• Taken together, more than 70% of Western Province adults were found to have either diabetes or prediabetes.
• And critically: over a third of those with diabetes did not know they had it.

Read that last line again. In a group of ten adults in Ja-Ela, Wattala or Kandana, the statistics suggest roughly seven have blood sugar outside the healthy range — and several of them have no idea.

Diabetes is largely silent until it has already done damage to the kidneys, eyes, nerves and blood vessels. A blood test is the only way to find it early.

What HbA1c actually measures

Glucose in your blood sticks to haemoglobin, the protein inside red blood cells. The more glucose there has been, the more haemoglobin gets coated. Red cells live about three months, so measuring the coated fraction gives you a weighted average of the last 2–3 months — most heavily reflecting the most recent weeks.

The useful consequence: you cannot cheat it by eating carefully for two days before the test. A fasting sugar can be talked into looking respectable. HbA1c reports what has actually been happening.

Reading the ranges

Two honest caveats:

1. These are the widely used international thresholds, not a diagnosis. Diagnosing diabetes normally requires confirmation — a repeat test, or a second type of test — and always a doctor's judgement about your whole situation.
2. Sri Lankan research has questioned whether the standard cut-off fits our population. A study of high-risk Sri Lankan adults found the best-performing HbA1c cut-off for detecting diabetes was around 6.3%, with better sensitivity but lower specificity than fasting plasma glucose. In practice this is one more reason your doctor will look at HbA1c alongside a fasting sugar rather than in isolation.

HbA1c vs fasting sugar vs OGTT — which do you need?

The pragmatic combination most doctors like: a Fasting Blood Sugar plus an HbA1c. One shows today, the other shows the last three months, and together they are far harder to misread than either alone. That's LKR 2,380 at our published prices — see the full price list.

When HbA1c can mislead

HbA1c depends on red blood cells behaving normally. It becomes less reliable if you have:

• Anaemia, especially iron-deficiency anaemia
• Thalassaemia trait or other haemoglobin variants — relevant in Sri Lanka
• Recent significant blood loss or a blood transfusion
• Chronic kidney or liver disease
• Pregnancy — glucose testing, usually an OGTT, is preferred

This is precisely why a Full Blood Count (LKR 400) is often run alongside. If your red cells are abnormal, your HbA1c number needs to be read differently — and your doctor needs to know.

Who should get tested

Consider testing, and talk to a doctor about how often, if you:

• Are over 35, or over 30 with any risk factor below
• Carry weight around the middle — South Asians develop metabolic problems at lower BMI than European populations
• Have a parent or sibling with diabetes
• Had gestational diabetes, or a baby over 4 kg
• Have high blood pressure or an abnormal lipid profile (LKR 1,500)
• Have PCOS
• Are not very physically active
• Notice increased thirst, frequent urination, unexplained weight loss, blurred vision, slow-healing wounds or persistent tiredness — though by the time symptoms show, blood sugar has usually been high for a while

Prediabetes is the stage worth finding

Here is the genuinely hopeful part, and the reason this test is worth the LKR 2,100.

Prediabetes is not a mild diabetes. It is a warning, and it is frequently reversible. Large international trials have consistently shown that sustained modest weight loss and regular physical activity substantially reduce the chance of progressing to type 2 diabetes — in several major studies, more effectively than medication did.

What that looks like in practice — and what to discuss with your doctor:

• Losing 5–10% of body weight if you're carrying extra, which for many people is 4–8 kg
• About 150 minutes of moderate activity a week — a brisk 30-minute walk, five days
• Cutting sugary drinks and refined starch, and moderating white rice portions
• Recheck at the interval your doctor advises, typically annually, so you can see whether it's working

Nobody reverses a diagnosis they never received. That's the whole argument for testing.

Already diagnosed? The check people skip

If you're living with diabetes, HbA1c monitoring is only half the job. Diabetes damages kidneys quietly, and the earliest detectable sign appears in urine long before creatinine rises.

• Urine Microalbumin / UACR — LKR 1,400. Detects tiny amounts of protein leaking into urine: the earliest warning of diabetic kidney damage, at a stage where action still helps.
• Serum Creatinine with GFR — LKR 700. How well the kidneys are filtering.
• Diabetic Kidney Profile — LKR 3,600. Urine Microalbumin (UACR), Serum Electrolytes, Ionized Calcium and Serum Creatinine with GFR in one visit.
• Full Body Health Check — LKR 4,700. For an annual all-round screen: FBC, ESR, FBS, Lipid Profile, SGOT, SGPT, Serum Creatinine, Blood Urea and Urine Full Report.

No fasting, no queue

Frequently asked questions

How much does an HbA1c test cost in Ja-Ela? LKR 2,100 at St. Luke's Medical Laboratory, No. 67, Old Negombo Road, Ja-Ela. Every test price we charge is published on our price list.

Do I need to fast for an HbA1c test? No. HbA1c requires no fasting and can be done at any time of day, before or after eating. Only pair it with fasting if your doctor has also ordered a Fasting Blood Sugar.

What is a normal HbA1c? Below 5.7% is generally considered normal, 5.7–6.4% indicates prediabetes, and 6.5% or above suggests diabetes. Your doctor interprets the result in the context of your health, and a diagnosis is not made on a single number.

Which is better, HbA1c or fasting blood sugar? Neither replaces the other. Fasting sugar (LKR 280) is a single point in time and is cheaper; HbA1c (LKR 2,100) gives a 2–3 month average that cannot be influenced by a day of careful eating. Most doctors prefer to see both.

How often should I check my HbA1c? If you have diabetes, typically every 3–6 months depending on control. If you have prediabetes, usually once a year. If you're screening with no risk factors, follow your doctor's advice. Testing more often than every 3 months rarely adds information, since the test itself reflects a 3-month span.

Can prediabetes be reversed? Frequently, yes. Sustained weight loss of around 5–10% and regular physical activity have been shown in major trials to substantially reduce progression to type 2 diabetes. Discuss a plan with your doctor.

Why might my HbA1c be inaccurate? Because it depends on red blood cells. Anaemia, thalassaemia trait and other haemoglobin variants, recent blood loss or transfusion, chronic kidney or liver disease, and pregnancy can all distort it. A Full Blood Count (LKR 400) alongside helps your doctor spot this.

How common is diabetes in the Western Province? Published survey data puts age-and-sex standardised diabetes prevalence in the Western Province at 27.8%, with more than 70% of adults having diabetes or prediabetes, and over a third of those with diabetes undiagnosed.

Can I get the test done at home? Yes. HbA1c needs no fasting, which makes it ideal for home collection. We cover all seven towns we serve plus home visits to Seeduwa, Katunayake and Negombo. Call 071 123 1954.
