Understanding the result
This result should be interpreted with symptoms, medical history and other investigations. An abnormal value does not identify the cause by itself.
About Fasting Blood Sugar (FBS)
Fasting Blood Sugar (FBS) measures your glucose level after 10–12 hours of overnight fasting. It is the primary test for diagnosing diabetes (126 mg/dL+) and prediabetes (100–125 mg/dL). Results in just 6 hours from NABL-certified labs.
Who may need it?
A healthcare professional may recommend this test based on your symptoms, medical history, risk factors or need for routine monitoring.
Normal Values and What They Mean
Below 100 mg/dL is normal. Between 100 and 125 mg/dL indicates prediabetes — your blood sugar is elevated but has not yet reached diabetic levels. At 126 mg/dL or above on two separate occasions, diabetes is diagnosed. In India, over 77 million people live with Type 2 diabetes; another 136 million are in the prediabetic range.Why FBS Should Be Combined with HbA1c
FBS reflects only the past few hours. A person can have a normal fasting glucose but elevated post-meal spikes or an HbA1c in the prediabetic range. For complete diabetes screening, booking FBS alongside HbA1c gives a far more accurate picture — FBS for today's value, HbA1c for the 3-month average.Preparation and Process
