The Diabetes Epidemic in Pakistan
Pakistan is facing a diabetes crisis of staggering proportions. According to the International Diabetes Federation (IDF), Pakistan currently has over 33 million adults living with diabetes, ranking it among the top 10 countries worldwide for diabetes prevalence. Even more alarming is that an estimated 25% of people with diabetes in Pakistan are undiagnosed — meaning millions of Pakistanis are walking around with elevated blood sugar levels that are silently damaging their heart, kidneys, eyes, nerves, and blood vessels without them knowing it. This makes laboratory testing for diabetes not just important, but absolutely critical.
At Doctors Space laboratory in Citi Housing, Gujranwala, we offer a complete range of diabetes diagnostic and monitoring tests. Whether you need an initial screening test, a confirmatory diagnosis, or regular monitoring of your diabetes control, our laboratory provides accurate, timely results using internationally standardized methods. This guide will help you understand each diabetes test, what the results mean, and how they are used to keep you healthy.
Are You at Risk for Diabetes?
You should be tested for diabetes if you are overweight or obese, have a family history of diabetes, are over 35 years old, have high blood pressure, have a history of gestational diabetes, or belong to a high-risk ethnic group (South Asians are at particularly high risk). If you have any of these risk factors, schedule a diabetes screening at Doctors Space Gujranwala today.
Fasting Blood Sugar (FBS) — The Most Common Diabetes Test
The Fasting Blood Sugar (FBS) test measures your blood glucose level after an overnight fast of at least 8 hours. It is the most commonly ordered initial test for diabetes screening. Fasting is important because it eliminates the immediate effect of food on blood sugar, giving a baseline reading of your body's ability to regulate glucose. The test requires only a small blood sample, usually drawn from a vein in your arm at Doctors Space laboratory.
| FBS Result | Category | Interpretation | Recommended Action |
|---|---|---|---|
| 70–99 mg/dL | Normal | Healthy fasting glucose level | Continue routine screening every 3 years (or annually if risk factors) |
| 100–125 mg/dL | Pre-diabetes (IFG) | Impaired Fasting Glucose — elevated but not yet diabetic | Lifestyle changes, retest in 6 months, consider OGTT |
| 126 mg/dL or above | Diabetes | Meets diagnostic criteria for diabetes (confirmed on 2 separate tests) | Start treatment, HbA1c testing, diabetes education |
| Below 70 mg/dL | Hypoglycemia | Abnormally low blood sugar | Evaluate for causes; may be related to diabetes medication or other conditions |
HbA1c — The Gold Standard for Diabetes Monitoring
The HbA1c test (also called glycated hemoglobin, hemoglobin A1c, or simply A1c) is arguably the most important test for anyone with diabetes. While FBS gives you a snapshot of your blood sugar at a single moment in time, HbA1c provides a long-term average of your blood sugar over the past 2–3 months. This is possible because glucose molecules attach (glycate) to hemoglobin in your red blood cells at a rate proportional to the average blood sugar level. Since red blood cells live for about 120 days, the HbA1c reflects your average glucose over their lifespan.
| HbA1c Level | Estimated Average Glucose | Category | Clinical Significance |
|---|---|---|---|
| Below 5.7% | ~117 mg/dL or less | Normal | No diabetes. Continue routine screening. |
| 5.7–6.4% | ~117–137 mg/dL | Pre-diabetes | High risk of developing diabetes. Intensive lifestyle modification needed. |
| 6.5% or above | ~140 mg/dL or above | Diabetes | Diagnostic of diabetes. Treatment and regular monitoring required. |
| Below 7% | — | Target for most adults with diabetes | Good diabetes control. Low risk of complications. |
| Above 8% | — | Poor control | High risk of complications. Treatment adjustment needed. |
| Above 9% | — | Very poor control | Urgent treatment intensification required. |
Advantages of HbA1c Testing
Unlike FBS, the HbA1c test does not require fasting and can be drawn at any time of day. It reflects your overall blood sugar control over the past 2–3 months, not just a single reading. This makes it a more reliable indicator of your true glucose control and your risk of developing diabetes complications.
Oral Glucose Tolerance Test (OGTT)
The Oral Glucose Tolerance Test (OGTT) is a more detailed test that measures how your body handles glucose over time. After an overnight fast, a baseline blood sample is drawn. You then drink a sweet glucose solution containing 75 grams of glucose, and blood samples are taken at intervals — typically at 30 minutes, 1 hour, and 2 hours — to measure how quickly your blood sugar rises and falls. The 2-hour value is used for diagnosis.
- 2-hour glucose below 140 mg/dL: Normal glucose tolerance
- 2-hour glucose 140–199 mg/dL: Impaired Glucose Tolerance (pre-diabetes)
- 2-hour glucose 200 mg/dL or above: Diabetes mellitus
- OGTT in pregnancy: Uses different criteria (90 mg/dL fasting, 180 mg/dL at 1 hour, 153 mg/dL at 2 hour — any two elevated values diagnose gestational diabetes)
OGTT vs. FBS for Diagnosis
The OGTT is more sensitive than FBS for detecting early diabetes and pre-diabetes. However, it is more time-consuming (takes 2–3 hours) and requires the patient to remain at the laboratory. At Doctors Space Gujranwala, we recommend OGTT for patients with borderline FBS results, women being screened for gestational diabetes, and patients with normal FBS but clinical features suggesting diabetes.
Insulin and C-Peptide Testing
While glucose tests tell you what your blood sugar level is, insulin and C-peptide tests tell you why it is at that level. These tests evaluate your pancreatic beta-cell function and help distinguish between Type 1 and Type 2 diabetes. Fasting insulin measures the amount of insulin in your blood after fasting. High fasting insulin with normal or elevated glucose indicates insulin resistance — the hallmark of Type 2 diabetes and metabolic syndrome. C-peptide is a byproduct of insulin production that is released in a 1:1 ratio with insulin but has a longer half-life, making it a more stable marker of insulin production.
| Test | Normal Range | Low Values Indicate | High Values Indicate |
|---|---|---|---|
| Fasting Insulin | 2–25 μIU/mL | Type 1 diabetes, pancreatic damage, low insulin production | Insulin resistance, Type 2 diabetes early stage, insulinoma |
| C-Peptide | 0.8–3.1 ng/mL | Type 1 diabetes, beta cell failure | Insulin resistance, insulinoma, kidney disease |
| HOMA-IR | < 2.5 | Normal insulin sensitivity | Insulin resistance (calculated from fasting glucose and insulin) |
Kidney and Liver Tests for Diabetes Patients
Diabetes does not only affect blood sugar — it damages multiple organ systems over time. Two of the most commonly affected organs are the kidneys and the liver. At Doctors Space Gujranwala, we recommend that all diabetes patients have regular kidney and liver function testing as part of their diabetes management plan.
- Urine Albumin-to-Creatinine Ratio (UACR): Detects the earliest signs of diabetic kidney disease. Normal is below 30 mg/g. Values 30–300 indicate microalbuminuria (early kidney damage). Above 300 indicates macroalbuminuria (significant kidney disease).
- Serum Creatinine and eGFR: Measures overall kidney function. Diabetes patients should have eGFR checked at least annually. Declining eGFR indicates progressive kidney damage.
- Liver Function Tests (ALT, AST): Diabetes patients are at high risk for Non-Alcoholic Fatty Liver Disease (NAFLD). Elevated liver enzymes may indicate fatty liver, which affects up to 70% of Type 2 diabetes patients.
- Lipid Profile: Diabetes patients typically have a characteristic lipid pattern: high triglycerides, low HDL, and small dense LDL particles. Annual lipid profiling is recommended.
- Uric Acid: Elevated uric acid is associated with metabolic syndrome and insulin resistance. It also increases the risk of gout.
Recommended Testing Schedule for Diabetes Patients
| Test | Frequency | Purpose |
|---|---|---|
| Fasting Blood Sugar | Daily (self-monitoring) + Quarterly (lab) | Day-to-day glucose management and lab confirmation |
| HbA1c | Every 3 months (if not at goal) or 6 months (if stable) | Long-term glucose control assessment |
| Lipid Profile | Annually (or more often if abnormal) | Cardiovascular risk assessment |
| Renal Function (Creatinine, eGFR) | Annually | Detection of diabetic nephropathy |
| Urine Albumin (UACR) | Annually | Early detection of kidney damage |
| Liver Function Tests | Annually | Screening for NAFLD and medication monitoring |
| Thyroid Function (TSH) | Annually | Thyroid disorders are common in diabetes patients |
| Complete Eye Examination | Annually | Detection of diabetic retinopathy |
| Vitamin B12 | Annually (if on metformin) | Metformin can cause B12 deficiency |
| Hb and CBC | Annually | Screening for anemia |

Fructosamine — An Alternative to HbA1c
In certain situations, HbA1c may not accurately reflect blood sugar control. This can occur in patients with hemoglobin disorders (like thalassemia, which is common in Pakistan), recent blood loss or transfusions, hemolytic anemia, pregnancy, or chronic kidney disease. In these cases, the fructosamine test can be used as an alternative. Fructosamine measures glycated proteins (primarily albumin) in the blood and reflects average blood sugar over the past 2–3 weeks rather than 2–3 months. Normal fructosamine levels range from 200–285 μmol/L.
