The Complete Blood Sugar Levels Chart: Your Guide to Normal, Prediabetes & Diabetes Ranges
Understanding your blood sugar levels is crucial for managing your health, especially if you have diabetes or are at risk. This comprehensive guide provides a detailed blood sugar levels chart, outlining normal ranges, prediabetes, and diabetes levels. We'll explore different types of blood sugar tests and what the results mean for you. This guide should serve as informational resource only, and not medical advise. Consult your health practitioner if you have questions.
Why Monitor Your Blood Sugar Levels?
Regularly monitoring your blood glucose (another term for blood sugar) helps you:

- Identify and manage diabetes or prediabetes.
- Understand how diet, exercise, and medications affect your blood sugar.
- Reduce the risk of long-term complications associated with diabetes.
- Make informed decisions about your health and lifestyle.
Types of Blood Sugar Tests
Several types of blood tests are used to measure blood sugar levels. Each test provides different insights into your glucose control:
- Fasting Blood Sugar (FBS): Measures blood sugar after an overnight fast (typically 8 hours).
- Random Blood Sugar (RBS): Measures blood sugar at any time of day, regardless of when you last ate.
- A1C Test: Measures your average blood sugar level over the past 2-3 months. This is NOT a blood sugar level itself. It measures how much glucose has attached to your red blood cells.
- Oral Glucose Tolerance Test (OGTT): Measures blood sugar levels before and after drinking a sugary liquid. This test is often used to diagnose gestational diabetes.
The Blood Sugar Levels Chart: Understanding Your Results
Here's a breakdown of the blood sugar levels for each type of test. Please note that these ranges are general guidelines and may vary slightly depending on the laboratory and individual circumstances. Consult with your doctor for personalized advice.
Fasting Blood Sugar (FBS) Levels
| Category | Fasting Blood Sugar Level (mg/dL) | Interpretation |
|---|---|---|
| Normal | Less than 100 | Indicates healthy **blood glucose** levels. |
| Prediabetes | 100 to 125 | Indicates an increased risk of developing diabetes. Lifestyle changes can help prevent progression to diabetes. |
| Diabetes | 126 or higher | Indicates diabetes. Requires management through diet, exercise, and/or medication. |
Random Blood Sugar (RBS) Levels
| Category | Random Blood Sugar Level (mg/dL) | Interpretation |
|---|---|---|
| Normal | Less than 200 (but highly variable) | This is just an indicative guideline. Random **blood sugar levels** vary depending on the person's last meal. If high, it may warrant further testing. |
| Diabetes | 200 or higher (with symptoms of diabetes) | If you experience symptoms like increased thirst, frequent urination, and unexplained weight loss, this level suggests diabetes. |
A1C Levels
The A1C test provides an average blood sugar level over the past 2-3 months and is crucial for diabetes management.
| Category | A1C Level (%) | Interpretation |
|---|---|---|
| Normal | Less than 5.7 | Indicates good **blood glucose** control. |
| Prediabetes | 5.7 to 6.4 | Indicates an increased risk of developing diabetes. Lifestyle changes are recommended. |
| Diabetes | 6.5 or higher | Indicates diabetes. Requires active management to control **blood sugar levels**. |
Oral Glucose Tolerance Test (OGTT) Levels
This test is primarily used to diagnose gestational diabetes during pregnancy, and can also diagnose type 2 diabetes.
| Category | 2-Hour OGTT Level (mg/dL) | Interpretation |
|---|---|---|
| Normal | Less than 140 | Indicates normal **glucose tolerance**. |
| Prediabetes | 140 to 199 | Impaired **glucose tolerance** suggests increased risk. |
| Diabetes | 200 or higher | Indicates diabetes. Requires medical intervention. |
