The Fasting Plasma Glucose (FPG) Test is a simple blood test that measures the amount of sugar (glucose) in your blood after an overnight fast, helping diagnose diabetes or assess blood sugar levels. It's commonly used to monitor and manage diabetes or determine the risk of developing the condition.
Here are the basic details of the FPG Test.

FPG Abnormal Test Report
Here is the normal range of the FPG Test
Category | FPG Test Normal Range |
---|---|
Normal | 70-100 mg/dL (3.9-5.6 mmol/L) |
Here is the Interpretation of the FPG Test.
FPG Level | Interpretation |
---|---|
Below 70 mg/dL | Hypoglycemia (low blood sugar), which may require medical attention. |
70 - 99 mg/dL | Normal blood glucose levels. |
100 - 125 mg/dL | Prediabetes - increased risk of developing diabetes. |
126 mg/dL or higher | Diabetes - blood glucose levels consistent with diabetes. |
Here are the potential causes of high FPG Test levels:
Potential Causes | Explanation |
---|---|
Diabetes | Chronic condition, insulin regulation issues. |
Prediabetes | Early-stage of diabetes, impaired glucose metabolism. |
Poor diet and lifestyle choices | High sugar intake, lack of physical activity. |
Medications | Some medications can elevate blood sugar levels. |
Stress | Stress hormones can affect blood glucose levels. |
Here are the potential causes of low FPG Test levels:
Potential Causes | Explanation |
---|---|
Hypoglycemia | Low blood sugar, often due to excessive insulin, medication, or dietary factors. |
Fasting too long | Extended fasting period before the test. |
Excessive physical activity | Strenuous exercise without proper carbohydrate intake. |
Medications | Some medications can lower blood sugar levels. |
Rare medical conditions | Insulin-producing tumors or severe metabolic disorders. |
