The Complete Guide to Your Blood Sugar Test Results (mg/dL vs mmol/L)
Understanding your blood sugar test results is crucial for managing your health, especially if you have diabetes or are at risk. Navigating the numbers can be confusing, especially with different measurement units like mg/dL and mmol/L. This guide will break down everything you need to know about interpreting your blood glucose levels, what the different units mean, and what actions you might need to take.
Why Blood Sugar Testing Matters
Regular blood glucose monitoring is a cornerstone of diabetes management. It helps you:
- Understand how food, exercise, and medication affect your blood sugar.
- Identify trends and patterns in your blood glucose levels.
- Make informed decisions about your diet, exercise, and medication dosages.
- Reduce your risk of developing serious diabetes-related complications.

Even if you don't have diabetes, regular checkups including blood sugar tests can help you detect prediabetes early, allowing you to make lifestyle changes that can prevent the progression to type 2 diabetes.
Understanding the Measurement Units: mg/dL and mmol/L
Blood glucose is measured in two primary units:
- mg/dL (milligrams per deciliter): This unit is commonly used in the United States, Japan, and Israel.
- mmol/L (millimoles per liter): This unit is widely used in Canada, Europe, and other parts of the world.
It's important to know which unit your blood sugar test results are reported in to properly interpret them. You can usually find the unit listed on your lab report or your blood glucose meter.
Converting Between mg/dL and mmol/L
You can easily convert between the two units using the following formulas:
- mg/dL to mmol/L: Divide mg/dL by 18
- mmol/L to mg/dL: Multiply mmol/L by 18
For example:
- If your blood sugar is 100 mg/dL, it is approximately 5.5 mmol/L (100 / 18 = 5.55).
- If your blood sugar is 7.0 mmol/L, it is approximately 126 mg/dL (7.0 * 18 = 126).
Many online calculators and apps can also perform this conversion for you.
Interpreting Your Blood Sugar Test Results: Target Ranges
The target range for blood glucose varies depending on the individual, the type of diabetes (if any), and the time of day the test is taken. The following table provides general guidelines:
| Category | Fasting Blood Sugar (mg/dL) | Fasting Blood Sugar (mmol/L) | 2-Hour Postprandial (After Meal) Blood Sugar (mg/dL) | 2-Hour Postprandial (After Meal) Blood Sugar (mmol/L) |
|---|---|---|---|---|
| Normal | Less than 100 | Less than 5.6 | Less than 140 | Less than 7.8 |
| Prediabetes | 100 to 125 | 5.6 to 6.9 | 140 to 199 | 7.8 to 11.0 |
| Diabetes | 126 or higher | 7.0 or higher | 200 or higher | 11.1 or higher |
Important Considerations:
- These are general guidelines. Your doctor may recommend different target ranges based on your individual circumstances.
- Fasting blood sugar is measured after at least eight hours of fasting (no food or drink other than water).
- 2-hour postprandial blood sugar is measured two hours after starting a meal.
Different Types of Blood Sugar Tests
Several different blood sugar tests are used to diagnose and manage diabetes:
- Fasting Plasma Glucose (FPG) Test: Measures your blood sugar after an overnight fast. This is a common test for diagnosing diabetes and prediabetes.
- Oral Glucose Tolerance Test (OGTT): Measures your blood sugar before and after you drink a sugary liquid. This test is often used to diagnose gestational diabetes.
- Random Plasma Glucose Test: Measures your blood sugar at any time of day, without regard to when you last ate.
- A1C Test: Measures your average blood sugar level over the past 2-3 months. This test provides a longer-term picture of blood sugar control.
What to Do if Your Blood Sugar is High or Low
High Blood Sugar (Hyperglycemia):
- Symptoms: Increased thirst, frequent urination, blurred vision, fatigue.
- Possible Causes: Eating too many carbohydrates, skipping medication, illness, stress.
- Actions: Drink plenty of water, check your blood sugar more frequently, adjust medication as directed by your doctor, and follow your meal plan. If you consistently have high blood sugar, consult with your doctor.
Low Blood Sugar (Hypoglycemia):
- Symptoms: Shakiness, sweating, dizziness, confusion, hunger, headache.
- Possible Causes: Skipping meals, taking too much insulin, excessive exercise.
- Actions: Follow the "15-15 rule": Eat 15 grams of fast-acting carbohydrates (e.g., glucose tablets, juice), wait 15 minutes, and check your blood sugar again. Repeat if necessary. Consult with your doctor if you experience frequent episodes of hypoglycemia.

- Interpret your blood sugar test results.
- Set realistic blood sugar goals.
- Develop a healthy eating plan.
- Create an exercise program.
- Adjust your medication as needed.
- Monitor for and manage diabetes-related complications.
Lifestyle Changes for Better Blood Sugar Control
In addition to medication, lifestyle changes play a vital role in managing blood sugar. Here are some key strategies:
- Healthy Eating: Focus on whole, unprocessed foods, including fruits, vegetables, whole grains, and lean protein. Limit sugary drinks, processed foods, and unhealthy fats.
- Regular Exercise: Aim for at least 30 minutes of moderate-intensity exercise most days of the week. Exercise helps your body use insulin more effectively.
- Weight Management: Losing even a small amount of weight can improve your blood sugar control.
- Stress Management: Stress can raise your blood sugar. Find healthy ways to manage stress, such as exercise, yoga, or meditation.
- Adequate Sleep: Lack of sleep can negatively affect blood sugar levels. Aim for 7-8 hours of sleep per night.
Conclusion
Understanding your blood sugar test results, whether in mg/dL or mmol/L, is essential for managing your health and preventing complications associated with diabetes. By working closely with your healthcare team and adopting a healthy lifestyle, you can effectively control your blood glucose levels and live a long and healthy life. Remember to always consult with your doctor before making any significant changes to your diabetes management plan. Regularly monitoring your blood sugar is a proactive step towards better health and well-being.
