Fasting Blood Sugar (FBS) Test Overview

What is the Fasting Blood Sugar (FBS) Test?

The Fasting Blood Sugar (FBS) Test measures the level of glucose in your blood after an overnight fast, typically 8–12 hours. Glucose is the main source of energy for your body, and maintaining its levels within a normal range is crucial for overall health.

This test is primarily used to detect diabetes, prediabetes, and to monitor blood sugar control in patients already diagnosed with diabetes. High fasting blood sugar may indicate insulin resistance, insufficient insulin production, or undiagnosed diabetes, while unusually low levels can suggest hypoglycemia or other metabolic disorders.

Monitoring fasting blood sugar helps doctors guide treatment, recommend lifestyle changes, and prevent long-term complications such as cardiovascular disease, kidney damage, or nerve problems. It is a simple yet essential test for anyone concerned about their blood sugar or metabolic health.

Why Take the Fasting Blood Sugar (FBS) Test?

This test is recommended if you:

• Are at risk for diabetes or prediabetes

• Experience symptoms such as frequent urination, excessive thirst, unexplained weight changes, or fatigue

• Need monitoring for existing diabetes management

• Want to evaluate overall metabolic health and early detection of blood sugar imbalances

How is the Fasting Blood Sugar (FBS) Test Carried Out?

• A small blood sample is collected from your arm, usually in the morning after fasting overnight.

• The sample is sent to the lab, where glucose levels are measured.

• Results are interpreted by your doctor to evaluate blood sugar control and risk for diabetes.

How do I Prepare for the Fasting Blood Sugar (FBS) Test?

• Fasting: Do not eat or drink anything except water for 8–12 hours before the test.

• Activity: Avoid strenuous exercise the night before or morning of the test.

• Medications: Inform your doctor about any medications or supplements, as some can affect blood sugar levels.

Next Steps

If fasting blood sugar levels are abnormal, your doctor may:

• Recommend lifestyle changes such as diet modification and regular exercise

• Prescribe or adjust medications for blood sugar control

• Conduct additional tests, such as HbA1c or Oral Glucose Tolerance Test (OGTT), for a more comprehensive assessment

• Monitor blood sugar regularly to prevent complications
