DIABETIC CHECKUP Lab Tests

🧪 FBS (Fasting Blood Sugar) Test The Fasting Blood Sugar (FBS) test measures the level of glucose (sugar) in the blood after an overnight fast (usually 8–12 hours). It is a basic and widely used test to screen for and monitor diabetes mellitus and pre-diabetes. 🔬 Test Overview Parameter Details Test Name Fasting Blood Sugar (FBS) Sample Type Blood (venous sample) Fasting Required? ✅ Yes (8–12 hours, no food or drink except water) Turnaround Time Few hours to 1 day Units mg/dL (milligrams per deciliter) Purpose Diagnose diabetes or monitor glucose control 📊 Reference Ranges & Interpretation FBS Level Interpretation ✅ 70–99 mg/dL Normal fasting glucose ⚠️ 100–125 mg/dL Impaired fasting glucose (Pre-diabetes) ❗ ≥126 mg/dL Diabetes mellitus (confirm with repeat test) A single high reading may not be diagnostic. Doctors typically require a repeat test or additional tests like HbA1c or OGTT for confirmation. 🧬 Why FBS Is Important Detects early signs of impaired glucose metabolism Monitors diabetes management and medication effectiveness Used in routine health checkups and risk assessments 🩺 Associated Tests Test Purpose HbA1c Long-term glucose control (past 2–3 months) OGTT Glucose response after a glucose load Random Glucose Immediate glucose status Postprandial Glucose Blood sugar after meals ✅ Summary Test Fasting Blood Sugar (FBS) Sample Blood (venous) Fasting Required (8–12 hours) Normal Range 70–99 mg/dL Abnormal Results May indicate prediabetes or diabetes
