The Blood Sugar Fasting (BSF) and Postprandial (PP) blood sugar tests are some of the most common examinations done to evaluate a person’s glucose metabolism in the body which is essential for the diagnosing and management of diabetes and insulin resistance.
Fasting Blood Sugar (FBS) is the analysis of concentration of blood glucose after a fasting period (usually overnight). It determines the amount of glucose in the system and is used to measure the metabolic health of the person when he or she has not recently consumed any food.
Postprandial Blood Sugar (PPBS) aims to determine blood glucose levels of an individual after a meal (generally 2 hours after the meal) to understand the post meal glucose elimination from the blood. It aids in analyzing the secretion of insulin in response to food intake by the body.
Both the BSF and PPBS are important in diagnosing diabetes mellitus and pre diabetes, hypoglycemia and for monitoring the disease in people diagnosed with diabetes.
The Fasting (FBS) and Postprandial (PP) Blood Sugar Report is a type of document that provides the findings for the two tests conducted. The report usually contains the values of blood sugar for fasting and after a meal, checked against set limits. Moreover, it includes some explanation of the data that has been analyzed to aid in making proper decisions on managing the patient.
A Blood Sugar Fasting & PP Report usually includes:
Test | Description |
Fasting Blood Sugar (FBS) | Measures blood glucose levels after 8-12 hours of fasting, typically taken in the morning before eating. |
Postprandial Blood Sugar (PPBS) | Measures blood glucose levels 2 hours after consuming a meal to see how well the body processes glucose after eating. |
Part | Description |
Fasting Blood Sugar (FBS) | Blood glucose level after fasting for 8-12 hours. Reflects how the body manages glucose without food intake. |
Postprandial Blood Sugar (PPBS) | Blood glucose level measured 2 hours after eating. Reflects how well the body manages glucose after meals. |
Test Results | Displays the actual FBS and PPBS values, compared to normal reference ranges. |
Reference Ranges | Normal and abnormal ranges for FBS and PPBS, which help in interpreting the results. |
Interpretation | The physician’s explanation of the results, based on the patient’s overall health status. |
Test Parameter | Normal Range |
Fasting Blood Sugar (FBS) | 70 - 100 mg/dL (fasting for 8-12 hours) |
Postprandial Blood Sugar (PPBS) | Less than 140 mg/dL (measured 2 hours after eating) |
Parameter | Interpretation |
Fasting Blood Sugar (FBS) | High FBS : May indicate diabetes mellitus, insulin resistance, or pre-diabetes. |
Postprandial Blood Sugar (PPBS) | High PPBS : Can indicate diabetes, impaired glucose tolerance, or poor insulin response to meals. |
The Fasting Blood Sugar (FBS) and Postprandial Blood Sugar (PPBS) tests provide essential information about how the body regulates blood glucose levels:

Test | Interpretation |
Fasting Blood Sugar (FBS) | High : May indicate diabetes or pre-diabetes; further tests are recommended. |
Postprandial Blood Sugar (PPBS) | High : Can suggest diabetes or impaired glucose tolerance; a follow-up test is needed for diagnosis. |
