FBS

You should get an FBS test if you have symptoms of diabetes, such as excessive thirst, frequent urination, unexplained weight loss, fatigue, blurred vision, or slow-healing wounds. It is also recommended for routine check-ups after age 30–35, and for people with obesity, high blood pressure, PCOS, or a family history of diabetes. People with diabetes use it for monitoring.

Fast for 8–12 hours before an FBS test, drinking only plain water. Avoid tea, coffee, juice, chewing gum, and smoking during the fast. Give your sample in the morning. Take your diabetes medicines or insulin after the test unless your doctor advises otherwise, and avoid alcohol the night before.

Yes, fasting is required for an FBS (fasting blood sugar) test. You should fast for 8–12 hours before giving your sample, drinking only plain water. Avoid tea, coffee, juice, and chewing gum during this time. Don't fast longer than 14 hours, as this can affect the accuracy of your results.
