Preparation
Fasting Blood Glucose is the first test every diabetes workup begins with — your blood sugar after an 8 to 10 hour overnight fast, measured for just ₹49 with collection at your home anywhere in Trivandrum.
The number tells a clean story: below 100 mg/dL is normal, 100–125 is prediabetes (the window where lifestyle change genuinely reverses the trend), and 126 or above on two occasions confirms diabetes. In a state with one of India's highest diabetes rates, this ₹49 test is the cheapest health insurance information you can buy.
The fasting rule is what makes the reading meaningful — no food or sugary drinks for 8–10 hours; plain water is fine and encouraged. Book the first morning slot from 7 AM, have the draw, and eat breakfast right after. If you take diabetes medication, ask your doctor whether to take the morning dose before or after the test.
8 to 10 hours. Practical version: finish dinner by 9 PM, book the 7 AM slot, drink only water before the draw, and eat right after.
