The Ultimate Guide to Understanding 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. These results come in two main units: milligrams per deciliter (mg/dL) and millimoles per liter (mmol/L). This guide will break down everything you need to know to interpret your blood sugar levels and take proactive steps toward better health.
Why Is Blood Sugar Monitoring Important?
Blood sugar, or glucose, is the main source of energy for your body. Maintaining stable blood glucose levels is essential for proper organ function. When blood sugar is too high (hyperglycemia) or too low (hypoglycemia), it can lead to various health problems. Regular blood sugar monitoring helps:
- Identify potential health risks like diabetes.
- Manage existing conditions like type 1 diabetes, type 2 diabetes, and gestational diabetes.
- Adjust medication and lifestyle choices to maintain optimal blood sugar control.

Blood sugar levels are typically measured in one of two units:
- mg/dL (milligrams per deciliter): This unit is primarily used in the United States.
- mmol/L (millimoles per liter): This unit is primarily used in Canada, Europe, and other parts of the world.
The relationship between these two units is as follows:
- 1 mmol/L = 18 mg/dL
- 1 mg/dL = 0.0555 mmol/L
Common Blood Sugar Tests and Their Results
Several types of blood sugar tests are commonly used:
- Fasting Blood Sugar (FBS): Measured after an overnight fast (usually 8 hours).
- Random Blood Sugar (RBS): Measured at any time of the day, regardless of when you last ate.
- A1C Test (Glycated Hemoglobin): Provides an average blood sugar level over the past 2-3 months.
- Oral Glucose Tolerance Test (OGTT): Used to diagnose gestational diabetes and assess insulin resistance.
Let's break down the ideal ranges for each test using both mg/dL and mmol/L:

Fasting Blood Sugar (FBS)
| Category | mg/dL | mmol/L |
|---|---|---|
| Normal | Less than 100 | Less than 5.6 |
| Prediabetes | 100 to 125 | 5.6 to 6.9 |
| Diabetes | 126 or higher | 7.0 or higher |
Random Blood Sugar (RBS)
| Category | mg/dL | mmol/L |
|---|---|---|
| Normal | Less than 200 | Less than 11.1 |
| Diabetes | 200 or higher (with symptoms) | 11.1 or higher (with symptoms) |
A1C Test
| Category | % | Estimated Average Glucose (eAG) mg/dL | Estimated Average Glucose (eAG) mmol/L |
|---|---|---|---|
| Normal | Less than 5.7% | Less than 114 | Less than 6.3 |
| Prediabetes | 5.7% to 6.4% | 114 to 139 | 6.3 to 7.7 |
| Diabetes | 6.5% or higher | 140 or higher | 7.8 or higher |
Oral Glucose Tolerance Test (OGTT) - 2-Hour Post-Glucose Load
| Category | mg/dL | mmol/L |
|---|---|---|
| Normal | Less than 140 | Less than 7.8 |
| Prediabetes (Impaired Glucose Tolerance) | 140 to 199 | 7.8 to 11.0 |
| Diabetes | 200 or higher | 11.1 or higher |
Important Note: These ranges are general guidelines. Consult with your healthcare provider to determine the appropriate blood sugar targets for your individual needs and health status.
Factors Affecting Blood Sugar Levels
Many factors can influence blood sugar levels, including:

- Diet: Carbohydrates, especially refined sugars, have the most significant impact.
- Physical Activity: Exercise helps lower blood sugar by increasing insulin sensitivity.
- Medications: Certain medications, such as corticosteroids, can raise blood sugar. Diabetes medications, on the other hand, aim to lower it.
- Stress: Stress hormones can cause blood sugar to rise.
- Illness: Infections and illnesses can also elevate blood sugar.
- Sleep: Poor sleep can affect insulin sensitivity and blood sugar control.
What to Do If Your Blood Sugar Levels Are High
If your blood sugar test results indicate high blood sugar levels (hyperglycemia), consider the following steps:
- Consult Your Doctor: Discuss your results with your healthcare provider to determine the best course of action.
- Review Your Diet: Focus on a balanced diet with fewer processed carbohydrates and sugary drinks.
- Increase Physical Activity: Regular exercise can help lower blood sugar levels.
- Monitor More Frequently: Keep a closer eye on your blood sugar to understand how different factors affect your levels.
- Adjust Medication (If Applicable): Work with your doctor to adjust your diabetes medication as needed.
What to Do If Your Blood Sugar Levels Are Low
If your blood sugar test results indicate low blood sugar levels (hypoglycemia), it's crucial to take immediate action. Common symptoms include shakiness, sweating, dizziness, and confusion. Here's what to do:
- Consume Fast-Acting Carbohydrates: Eat or drink something that will quickly raise your blood sugar, such as glucose tablets, fruit juice, or regular soda.
- Recheck Your Blood Sugar: After 15 minutes, recheck your blood sugar to ensure it's rising.
- Eat a Meal or Snack: Once your blood sugar is back within the normal range, eat a meal or snack to prevent another drop.
- Identify the Cause: Work with your healthcare provider to identify what caused your blood sugar to drop too low and make adjustments to your medication or lifestyle accordingly.
Tips for Maintaining Healthy Blood Sugar Levels
Here are some general tips for maintaining healthy blood sugar levels:
- Eat a Balanced Diet: Focus on whole foods, lean proteins, and healthy fats. Limit processed foods, sugary drinks, and refined carbohydrates.
- Exercise Regularly: Aim for at least 30 minutes of moderate-intensity exercise most days of the week.
- Manage Stress: Practice relaxation techniques such as yoga, meditation, or deep breathing.
- Get Enough Sleep: Aim for 7-8 hours of quality sleep each night.
- Monitor Your Blood Sugar Regularly: If you have diabetes or are at risk, regular blood sugar monitoring is essential.
- Follow Your Doctor's Recommendations: Adhere to your healthcare provider's advice regarding medication, diet, and lifestyle changes.
Conclusion
Understanding your blood sugar test results, whether in mg/dL or mmol/L, is vital for managing your health. By knowing what the different tests measure, interpreting the results accurately, and taking proactive steps to maintain healthy blood sugar levels, you can significantly reduce your risk of diabetes and its complications. Always consult with your healthcare provider for personalized guidance and treatment plans.
