What Is an FBS Test?

A fasting blood sugar (FBS) test is a simple blood test that measures the amount of glucose (sugar) in your blood after you have not eaten for several hours. The test uses a blood sample drawn from a vein in your arm. This test helps detect and diagnose diabetes mellitus and prediabetes, and helps assess how well your body manages blood sugar levels.

What Does the FBS Test Measure?

The FBS blood test serves several important purposes in monitoring your health:

• Measures your baseline blood glucose levels when not influenced by recent food intake.
• Evaluates how effectively your body's insulin controls blood sugar.
• Screens for prediabetes and diabetes mellitus
• Assesses insulin resistance and glucose metabolism disorders.
• Monitors treatment effectiveness in people already diagnosed with diabetes.
• Helps identify fasting hyperglycaemia and related metabolic conditions.

FBS Test: Who Needs It and Why It's Done

What Symptoms May Call for an FBS Test?

Your doctor may recommend an FBS fasting test if you experience any of these common symptoms of high blood sugar:

• Frequent urination, especially at nighttime
• Increased thirst that doesn't go away even after drinking water
• Unexplained weight loss despite normal eating habits
• Constant hunger even after eating meals
• Blurred vision or difficulty seeing clearly
• Persistent fatigue and feeling very tired throughout the day
• Slow healing of cuts, wounds, or sores
• Frequent infections, particularly skin or gum infections

Who Should Get an FBS Test?

Several groups of people should consider getting an FBS fasting test regularly:

• Adults aged 35 years and above as part of routine health screening
• People with a family history of diabetes
• Individuals who are overweight or obese
• Those with high blood pressure or high cholesterol levels
• Women with polycystic ovary syndrome (PCOS)
• Women who had gestational diabetes during pregnancy
• People who lead sedentary lifestyles with minimal physical activity
• Individuals taking medications like steroids that can affect blood sugar
• Anyone experiencing symptoms of high blood sugar levels

Why Is an FBS Test Done?

An FBS test is performed because it provides a reliable and cost-effective way to screen for diabetes and prediabetes early. Early detection allows timely lifestyle changes and medical intervention to prevent serious complications.

Importance of an FBS Test

The FBS test is clinically crucial, as it serves as the primary screening tool for identifying diabetes and prediabetes before symptoms develop. This early detection is vital because it gives you the opportunity to make lifestyle modifications, such as improving your diet and increasing physical activity, to prevent or delay the onset of type 2 diabetes.

For those already diagnosed with diabetes, the FBS fasting test helps monitor how well treatment plans are working and guides adjustments to medications or lifestyle changes. Regular FBS monitoring helps reduce the risk of long-term complications like heart disease, kidney damage, nerve problems, and vision issues.

Interpreting FBS Test Results

What Your FBS Test Results May Indicate

The table below shows the standard reference ranges for FBS test results and what different levels may indicate:

Parameter

Reference Range

High Values May Indicate

Low Values May Indicate

Glucose Fasting

Normal: 70-99 mg/dL


Impaired Fasting Glucose: 100-125 mg/dL


Diabetes mellitus: ≥ 126 mg/dL

Diabetes mellitus, prediabetes, insulin resistance, stress, certain medications, or pancreatic disorders

Hypoglycaemia, excessive insulin, certain medications, liver disease, or prolonged fasting

 

Conditions that May Affect FBS Test Accuracy

Several factors can influence your FBS fasting test results and should be discussed with your doctor:

• An insufficient fasting period (less than 8 hours) can lead to falsely elevated results.
• Dehydration can concentrate blood glucose, potentially showing higher readings.
• Stress, illness, or infections can temporarily raise blood sugar levels.
• Certain medications, including steroids, diuretics, and certain antidepressants, can raise glucose levels.
• Recent vigorous exercise or physical activity before the test.
• Smoking or consuming caffeine during the fasting period.
• Changes in your regular sleep pattern or lack of adequate sleep.
• Certain medical conditions, like liver disease or hormonal disorders, can impact readings.

How Is an FBS Test Done?

The FBS blood test procedure is straightforward and typically completed within a few minutes:

• A healthcare professional cleanses the area on your arm (usually inside the elbow) with an antiseptic.
• An elastic band (tourniquet) is tied around your upper arm to make the vein more visible.
• A sterile needle is inserted into the vein to draw about 2 ml of blood into a fluoride vacutainer.
• The tourniquet and needle are removed, and pressure is applied to stop any bleeding.
• A small bandage is placed over the puncture site.
• Your blood sample is labelled and sent to the laboratory for analysis.

How Should You Prepare for an FBS Test?

Proper preparation is essential for accurate FBS fasting test results:

Fast for 8-10 hours: Do not eat or drink anything except plain water during this period.
Continue regular medications: Take your prescribed medicines unless your doctor advises otherwise.
Avoid alcohol: Do not consume alcoholic beverages for at least 24 hours before the test.
Stay hydrated: Drink plenty of water during the fasting period to prevent dehydration.
Avoid smoking: Do not smoke cigarettes during the fasting period.
Get adequate sleep: Ensure you have proper rest the night before your test.
Avoid strenuous exercise: Refrain from intense physical activity on the morning of the test.

Diseases that an FBS Test Can Help Detect

The FBS test is valuable in diagnosing and monitoring several important health conditions:

• Type 1 diabetes mellitus
• Type 2 diabetes mellitus
• Gestational diabetes in pregnant women
• Prediabetes (impaired fasting glucose)
• Insulin resistance syndrome
• Metabolic syndrome
• Pancreatic disorders affecting insulin production
• Hypoglycaemia (low blood sugar conditions)
• Secondary diabetes due to other medical conditions

Frequently Asked Questions

Diabetes can be controlled through a balanced diet rich in fibre and low in processed sugars, regular physical activity for at least 150 minutes weekly, maintaining a healthy weight, monitoring blood sugar levels regularly, and taking prescribed medications as directed by your doctor.

Type 2 diabetes is a chronic condition where your body either doesn't produce enough insulin or becomes resistant to insulin. This causes glucose to build up in your bloodstream instead of being used for energy by your cells.

Prediabetes means your blood sugar levels are higher than normal but not yet high enough for a diabetes diagnosis. It can often be reversed through lifestyle changes, like weight loss, healthy eating, and increased physical activity.

Factors include diet type and timing, physical activity levels, stress, illness or infections, certain medications like steroids, lack of sleep, dehydration, and hormonal changes. These can cause temporary fluctuations in blood sugar readings.

The best time for an FBS test is early morning after an overnight fast of 8-10 hours. This ensures accurate baseline glucose measurement without influence from recent food intake or daily activities.

Yes, overnight fasting is mandatory for 8-10 hours before the FBS fasting test. During this period, you should not eat or drink anything except plain water to ensure accurate glucose measurement results.

Yes, dehydration can affect your FBS test results by concentrating glucose in your blood, potentially leading to falsely elevated readings. It's important to stay hydrated by drinking water during your fasting period.

Fast for 8-10 hours before the test, drinking only plain water. Continue taking your regular medications unless your doctor advises otherwise. Avoid alcohol for 24 hours and inform the doctor about all medications you're taking.

A healthcare professional cleans your arm, applies a tourniquet, inserts a sterile needle into your vein, and collects 2 ml of blood in a fluoride tube. The procedure takes less than 5 minutes and causes minimal discomfort.

The FBS normal level is 70-99 mg/dL. Levels between 100-125 mg/dL indicate impaired fasting glucose (prediabetes), while levels of 126 mg/dL or higher on multiple occasions suggest diabetes mellitus requiring further medical evaluation.
