Blood Sugar Diagnosis Levels: Understanding the Ranges for mg/dL & mmol/L
Understanding blood sugar levels is crucial for managing and preventing diabetes. Whether you're monitoring your health or simply curious, knowing the diagnostic ranges for blood glucose levels can empower you to take proactive steps. This article breaks down the specific levels used to diagnose diabetes and prediabetes, explaining the differences between mg/dL and mmol/L, and how to interpret your results.
What are Blood Sugar Levels?
Blood sugar, also known as blood glucose, refers to the concentration of glucose in your blood. Glucose is your body's primary source of energy and comes from the food you eat. Blood sugar levels fluctuate throughout the day, rising after meals and decreasing as your body uses glucose for energy. Maintaining healthy blood sugar levels is essential for overall health.
Why is Monitoring Blood Sugar Important?
Regular monitoring of blood glucose levels is important for several reasons:
- Diagnosis of Diabetes and Prediabetes: It helps identify whether your blood sugar levels fall within the normal range or indicate a risk for or presence of diabetes.
- Management of Existing Diabetes: For those already diagnosed, it helps in managing their condition through diet, exercise, and medication.
- Prevention of Long-Term Complications: Keeping blood sugar levels within the target range reduces the risk of long-term complications associated with diabetes, such as heart disease, kidney disease, and nerve damage.
- General Health Awareness: Even without diabetes, knowing your blood sugar range provides insights into your body's metabolic health.
Understanding Units of Measurement: mg/dL vs. mmol/L
Blood sugar levels are commonly measured in two different units:
- mg/dL (milligrams per deciliter): This is the standard unit of measurement used in the United States.
- mmol/L (millimoles per liter): This is the standard unit of measurement used in many countries, including Canada and Europe.
To convert between the two units, you can use the following formula:

- mg/dL = mmol/L x 18
- mmol/L = mg/dL / 18
It’s important to know which unit of measurement your lab uses to accurately interpret your results.
Blood Sugar Diagnosis Levels: A Detailed Breakdown
Blood sugar is measured through various tests including fasting blood sugar (FBS), oral glucose tolerance test (OGTT), and A1C test. Each test has specific diagnostic criteria, detailed below.
1. Fasting Blood Sugar (FBS)
A fasting blood sugar test measures your blood glucose levels after an overnight fast (typically 8 hours). This test is a common method for screening and diagnosing diabetes.
| Category | mg/dL | mmol/L |
|---|---|---|
| Normal | Less than 100 mg/dL | Less than 5.6 mmol/L |
| Prediabetes (Impaired Fasting Glucose) | 100 to 125 mg/dL | 5.6 to 6.9 mmol/L |
| Diabetes | 126 mg/dL or higher | 7.0 mmol/L or higher |
A diagnosis of diabetes typically requires two separate tests with results in the diabetic range.
2. Oral Glucose Tolerance Test (OGTT)
The oral glucose tolerance test is used to assess how your body processes sugar after drinking a sugary solution. It involves fasting overnight, drinking a standard glucose solution, and then having your blood sugar levels tested periodically over the next two hours.
| Category | mg/dL (2-hour post-glucose load) | mmol/L (2-hour post-glucose load) |
|---|---|---|
| Normal | Less than 140 mg/dL | Less than 7.8 mmol/L |
| Prediabetes (Impaired Glucose Tolerance) | 140 to 199 mg/dL | 7.8 to 11.0 mmol/L |
| Diabetes | 200 mg/dL or higher | 11.1 mmol/L or higher |
This test is commonly used to diagnose gestational diabetes during pregnancy.
3. A1C Test
The A1C test, also known as the glycated hemoglobin test, provides an average of your blood sugar levels over the past 2-3 months. It does not require fasting and is a convenient way to monitor long-term blood glucose control.
| Category | A1C (%) |
|---|---|
| Normal | Less than 5.7% |
| Prediabetes | 5.7% to 6.4% |
| Diabetes | 6.5% or higher |
The A1C test is valuable for both diagnosing diabetes and monitoring how well blood sugar is being managed in individuals already diagnosed with diabetes.
4. Random Blood Sugar Test

A random blood sugar test measures your blood sugar at any time of the day, without regard to when you last ate.
| Category | mg/dL | mmol/L |
|---|---|---|
| Diabetes (if accompanied by symptoms) | 200 mg/dL or higher | 11.1 mmol/L or higher |
If the random blood sugar test shows a high level, further testing with either FBS or OGTT is generally needed.
What to Do if Your Blood Sugar Levels are High
If your blood glucose levels are consistently high, consult with a healthcare professional. Here are some steps they may advise:
- Lifestyle Changes: Diet modification, regular exercise, and weight management can significantly improve blood sugar control. Focus on consuming a balanced diet rich in fiber, lean proteins, and complex carbohydrates, while limiting processed foods, sugary drinks, and saturated fats.
- Medications: Depending on the severity of your condition, your doctor may prescribe oral medications or insulin to help regulate your blood sugar.
- Regular Monitoring: Frequent blood sugar monitoring allows you to track the effects of your lifestyle changes and medications, helping you and your healthcare provider make informed decisions about your treatment plan.
- Education: Educate yourself about diabetes management through reliable sources, support groups, and diabetes education programs. Understanding your condition can empower you to take control of your health.
Factors Affecting Blood Sugar Levels
Several factors can influence your blood glucose levels:
- Diet: Carbohydrate intake, especially refined carbs and sugars, directly impacts blood sugar.
- Physical Activity: Exercise helps lower blood sugar levels by increasing insulin sensitivity.
- Stress: Stress hormones can increase blood sugar levels.
- Medications: Certain medications can affect blood sugar, so consult with your healthcare provider if you’re concerned.
- Illness: Infections and illnesses can temporarily raise blood sugar.
