Gula dalam darah (glukosa) berubah sepanjang hari. Ia naik selepas makan dan turun semasa puasa. Sebab itulah satu bacaan sahaja tidak cukup; angka itu mesti ditafsir mengikut konteks: adakah anda berpuasa, baru selepas makan, ujian rawak, atau ujian purata 3 bulan (HbA1c)? Dan adakah ia bacaan glukometer cucuk jari atau ujian darah di makmal?
Blood sugar (glucose) changes throughout the day. It rises after meals and falls during fasting. That's why a single reading isn't enough; the number must be interpreted in context: are you fasting, just after a meal, a random test, or a 3-month average (HbA1c)? And is it a finger-prick meter reading or a lab blood test?
Carta di bawah menunjukkan julat normal, pradiabetes dan julat diabetes untuk setiap jenis ujian, supaya anda boleh padankan angka anda sendiri.
The chart below shows the normal, prediabetes and diabetes ranges for each test type. So you can match your own number.
Kenapa Angka Ini Penting di Malaysia
Why This Number Matters in Malaysia
Mengikut National Health and Morbidity Survey (NHMS) 2023, kira-kira 1 dari 6–7 dewasa Malaysia menghidap diabetes, dan ramai tidak tahu sehingga komplikasi muncul. Gula tinggi yang dibiarkan merosakkan mata, buah pinggang, saraf dan jantung secara senyap. Mengetahui bacaan anda lebih awal membolehkan pencegahan, terutama pada peringkat pradiabetes, ketika perkembangan kepada diabetes masih boleh dilambatkan.
According to the National Health and Morbidity Survey (NHMS) 2023, roughly 1 in 6–7 Malaysian adults has diabetes, and many don't know until complications appear. Unchecked high glucose silently damages the eyes, kidneys, nerves and heart. Knowing your reading early enables prevention, especially at the prediabetes stage, when progression to diabetes can still be delayed.

Carta Bacaan Gula Dalam Darah Ikut CPG KKM
Blood Sugar Chart (Malaysian CPG)
Padankan bacaan anda dengan baris ujian yang betul. Carta ini mengikut Jadual 2-3, 2-4 dan 2-5 CPG Pengurusan Diabetes Jenis 2 KKM (2020) untuk ujian darah vena di makmal. Nilai utama dalam mmol/L (unit standard di Malaysia); nilai dalam kurungan ialah mg/dL.
Match your reading to the correct test row. This chart follows Tables 2-3, 2-4 and 2-5 of the Malaysian CPG on Management of Type 2 Diabetes (2020) for venous blood tests in a lab. Main values are in mmol/L (Malaysia's standard unit); bracketed values are mg/dL.
Cara baca: lajur kuning (pradiabetes) ialah amaran awal, ketika perkembangan kepada diabetes masih boleh dilambatkan. Bagi gula rawak, bacaan 7.8 hingga 11.0 belum boleh dikelaskan dan CPG mengesyorkan ujian OGTT.
How to read it: the yellow column (prediabetes) is an early warning, when progression to diabetes can still be delayed. For random glucose, a reading of 7.8 to 11.0 cannot be classified yet and the CPG recommends an OGTT.
Lajur merah bermakna julat diabetes: tanpa simptom, doktor memerlukan dua ujian tidak normal untuk mengesahkannya. Perhatikan juga bahawa Malaysia menggunakan ambang HbA1c 6.3%, lebih rendah daripada 6.5% yang digunakan di sesetengah negara.
The red column means the diabetes range: without symptoms, a doctor needs two abnormal tests to confirm it. Note that Malaysia uses an HbA1c cut-off of 6.3%, lower than the 6.5% used in some countries.
Guna glukometer cucuk jari? CPG menggunakan glukometer untuk saringan awal sahaja, dengan ambang berbeza: bacaan puasa 5.6 mmol/L ke atas atau rawak 7.8 mmol/L ke atas perlu disahkan melalui ujian darah vena di makmal.
Using a finger-prick meter? The CPG uses meters for initial screening only, with different cut-offs: a fasting reading of 5.6 mmol/L or more, or a random reading of 7.8 mmol/L or more, needs confirming with a venous blood test in a lab.
Sudah menghidap diabetes? Sasaran CPG ialah 4.4 hingga 7.0 mmol/L sebelum makan, 4.4 hingga 8.5 mmol/L sekurang-kurangnya 90 minit selepas makan, dan HbA1c bawah 7.0% bagi kebanyakan pesakit. Semak bacaan anda terus dengan Kalkulator Gula Dalam Darah.
Already have diabetes? The CPG targets are 4.4 to 7.0 mmol/L before meals, 4.4 to 8.5 mmol/L at least 90 minutes after meals, and an HbA1c below 7.0% for most patients. Check your reading directly with the Blood Sugar Calculator.

Pradiabetes: Peluang Untuk Melambatkan Diabetes
Prediabetes: Your Chance to Delay Diabetes
Jika bacaan anda jatuh dalam julat pradiabetes (gula puasa 6.1 hingga 6.9 mmol/L, OGTT 2 jam 7.8 hingga 11.0 mmol/L, atau HbA1c 5.7% hingga 6.2%), inilah peluang terbaik anda. Pradiabetes meningkatkan risiko menjadi diabetes dan penyakit jantung, tetapi CPG menegaskan perkembangannya boleh dilambatkan.
If your reading falls in the prediabetes range (fasting 6.1 to 6.9 mmol/L, 2-hour OGTT 7.8 to 11.0 mmol/L, or HbA1c 5.7% to 6.2%), this is your best opportunity. Prediabetes raises the risk of diabetes and heart disease, but the CPG stresses that progression can be delayed.
Asasnya ialah perubahan gaya hidup yang intensif dengan sasaran penurunan berat badan sekurang-kurangnya 7%, pemakanan yang lebih sihat seperti mengurangkan gula dan karbohidrat bertapis, dan senaman sederhana sekurang-kurangnya 150 minit seminggu. Doktor juga akan menyemak tekanan darah dan kolesterol anda, kerana ia sering hadir bersama.
The foundation is intensive lifestyle change with a target of at least 7% weight loss, healthier eating such as cutting sugar and refined carbohydrates, and at least 150 minutes of moderate exercise a week. Your doctor will also check your blood pressure and cholesterol, as they often come together.
Bacaan Anda Tinggi? Ini Langkah Seterusnya
Your Reading Is High? Here Are Your Next Steps
Jangan panik dengan satu bacaan, tetapi jangan abaikannya juga. Langkah seterusnya:
Don't panic over a single reading, but don't ignore it either. Your next steps:
- Sahkan dengan ujian betul. Buat saringan diabetes & metabolik termasuk HbA1c + gula puasa, dan jumpa Pakar Perubatan Dalaman untuk pengesahan.
- Confirm with the right test. Do a diabetes & metabolic screening including HbA1c + fasting glucose, and see an Internal Medicine specialist for confirmation.
- Periksa organ yang berisiko. Gula tinggi menjejaskan jantung, mata dan buah pinggang secara senyap. Pertimbangkan saringan jantung, pemeriksaan mata (risiko katarak & retinopati), dan fungsi buah pinggang, atau buat pakej saringan kesihatan menyeluruh yang merangkumi semua ujian ini sekali gus.
- Check at-risk organs. High glucose silently affects the heart, eyes and kidneys. Consider a heart screening, an eye check (cataract & retinopathy risk), and kidney function, or get a comprehensive health screening package that covers all these tests at once.
- Mula ubah gaya hidup hari ini. Lihat panduan makanan yang menaikkan & menurunkan gula.
- Start lifestyle changes today. See our guide on foods that raise & lower blood sugar.
HbA1c atau Gula Puasa: Mana Lebih Tepat?
HbA1c or Fasting Glucose: Which Is More Accurate?
HbA1c (hemoglobin terglikat) menggambarkan purata gula darah anda dalam 3 bulan lepas. Tidak perlu puasa dan tidak terjejas oleh apa yang anda makan pagi itu. CPG menyatakan HbA1c mempunyai variasi paling rendah antara ujian (0.3% hingga 0.4%), berbanding 12% untuk gula puasa dan 20% untuk OGTT, jadi ia mudah dan konsisten untuk diagnosis dan pemantauan.
HbA1c (glycated haemoglobin) reflects your average blood sugar over the past 3 months. No fasting is needed and it is not affected by what you ate that morning. The CPG notes HbA1c has the lowest test-to-test variability (0.3% to 0.4%), compared with 12% for fasting glucose and 20% for the OGTT, making it convenient and consistent for diagnosis and monitoring.
Gula puasa (FPG) hanya gambaran satu masa, perlu puasa sekurang-kurangnya 8 jam, dan lebih berubah-ubah berbanding HbA1c. OGTT (oral glucose tolerance test) digunakan jika hasil samar-samar atau untuk skrin diabetes gestasi pada ibu hamil. Untuk pesakit pertama kali, kombinasi HbA1c + gula puasa selalunya disyorkan untuk konfirmasi diagnosis.
Fasting glucose (FPG) is a single snapshot, requires at least an 8-hour fast, and varies more than HbA1c. OGTT (oral glucose tolerance test) used if results are ambiguous or for gestational diabetes screening in pregnant women. For first-time patients, combination HbA1c + fasting glucose is usually recommended for confirmation.

Frequently Asked Questions (FAQ)
Apa bacaan gula dalam darah yang normal?
What is a normal blood sugar reading?
Menurut CPG Pengurusan Diabetes Jenis 2 KKM (2020), gula puasa darah vena di bawah 6.1 mmol/L (110 mg/dL) adalah normal, dan gula rawak di bawah 7.8 mmol/L (140 mg/dL) adalah normal. HbA1c normal di bawah 5.7%. Gula puasa 6.1 hingga 6.9 mmol/L atau HbA1c 5.7% hingga 6.2% ialah pradiabetes.
According to the Malaysian CPG on Management of Type 2 Diabetes (2020), a fasting venous blood glucose below 6.1 mmol/L (110 mg/dL) is normal, and a random glucose below 7.8 mmol/L (140 mg/dL) is normal. A normal HbA1c is below 5.7%. Fasting glucose of 6.1 to 6.9 mmol/L or HbA1c of 5.7% to 6.2% is prediabetes.
Gula puasa 7.0 mmol/L (126 mg/dL) ke atas atau HbA1c 6.3% ke atas berada dalam julat diabetes dan perlu disahkan oleh doktor. Untuk glukometer cucuk jari, bacaan puasa 5.6 mmol/L ke atas atau rawak 7.8 mmol/L ke atas perlu ujian pengesahan di makmal.
Fasting glucose of 7.0 mmol/L (126 mg/dL) or higher, or HbA1c of 6.3% or higher, is in the diabetes range and must be confirmed by a doctor. For finger-prick glucometers, a fasting reading of 5.6 mmol/L or higher, or a random reading of 7.8 mmol/L or higher, needs a confirmatory laboratory test.
Bacaan gula 7.0, adakah itu diabetes?
My blood sugar reading is 7.0. Is that diabetes?
Gula puasa darah vena 7.0 mmol/L (126 mg/dL) ialah ambang diagnosis diabetes. Namun tanpa simptom, diagnosis memerlukan dua ujian tidak normal, sama ada gula darah dan HbA1c daripada sampel yang sama atau dua sampel berasingan.
A fasting venous glucose of 7.0 mmol/L (126 mg/dL) is the diagnostic threshold for diabetes. Without symptoms, however, a diagnosis needs two abnormal results, either blood glucose and HbA1c from the same sample or from two separate samples.
Jika anda ada simptom jelas seperti kerap kencing dan dahaga, satu ujian sudah memadai. Jika bacaan 7.0 itu daripada glukometer, ia perlu disahkan di makmal dahulu.
If you have clear symptoms such as frequent urination and thirst, one test is enough. If the 7.0 reading came from a glucometer, it must first be confirmed in a laboratory.
Apa beza HbA1c dan gula puasa?
What is the difference between HbA1c and fasting glucose?
HbA1c menggambarkan purata gula darah dalam 3 bulan lepas dan tidak memerlukan puasa. Di Malaysia, HbA1c normal di bawah 5.7%, pradiabetes 5.7% hingga 6.2%, dan julat diabetes 6.3% ke atas.
HbA1c reflects your average blood sugar over the past 3 months and does not require fasting. In Malaysia, a normal HbA1c is below 5.7%, prediabetes is 5.7% to 6.2%, and the diabetes range is 6.3% or higher.
Gula puasa hanya gambaran satu masa dan memerlukan puasa sekurang-kurangnya 8 jam: normal di bawah 6.1 mmol/L, pradiabetes 6.1 hingga 6.9 mmol/L, dan diabetes 7.0 mmol/L ke atas. HbA1c paling kurang berubah-ubah antara ujian, dan gabungan kedua-duanya sering digunakan untuk pengesahan diagnosis.
Fasting glucose is a single snapshot and requires at least 8 hours of fasting: normal is below 6.1 mmol/L, prediabetes is 6.1 to 6.9 mmol/L, and diabetes is 7.0 mmol/L or higher. HbA1c varies the least between tests, and the two are often combined to confirm a diagnosis.
