Blood sugar test cost in Bangalore: FBS and PPBS explained (2026)
Fasting blood sugar and post-meal blood sugar are the two main tests for diabetes screening. Here is what they cost at Bangalore labs and how to get them right.
$## FBS vs PPBS: what is the difference?
Two tests are commonly used to screen for and monitor diabetes:
FBS (Fasting Blood Sugar): Measures your blood glucose after at least 8 hours of fasting. It reflects baseline glucose without the influence of recent food.
PPBS (Post-Prandial Blood Sugar): Measures blood glucose 2 hours after a meal. Also called PP glucose or 2-hour post-meal sugar. It shows how well your body clears glucose after eating.
Both tests are often ordered together for a more complete picture. A third option, the Oral Glucose Tolerance Test (OGTT), involves drinking a glucose solution and testing at intervals -- used primarily for diagnosing gestational diabetes.
Reference ranges (standard):
FBS:
- Below 100 mg/dL -- Normal
- 100 to 125 mg/dL -- Pre-diabetes (impaired fasting glucose)
- 126 mg/dL and above (on two occasions) -- Diabetes
PPBS:
- Below 140 mg/dL -- Normal
- 140 to 199 mg/dL -- Pre-diabetes (impaired glucose tolerance)
- 200 mg/dL and above -- Diabetes
Typical prices at Bangalore labs
FBS alone: Rs. 50 to 200
One of the cheapest tests available. Independent neighbourhood labs charge Rs. 50 to 100. Chain labs charge Rs. 100 to 200.
PPBS alone: Rs. 50 to 200
Similar pricing to FBS.
FBS + PPBS together: Rs. 100 to 350
Most labs offer a small discount when both are ordered together.
FBS + PPBS + HbA1c: Rs. 350 to 800. The most comprehensive diabetes screen. HbA1c adds the 3-month average picture alongside the single-point FBS and PPBS readings.
OGTT: Rs. 200 to 500. Requires you to spend 2 hours at the lab.
Fasting requirements
FBS: Fast for at least 8 hours before the test. Water is allowed. No medication changes unless instructed by your doctor.
PPBS: Eat a normal meal, then go to the lab exactly 2 hours after your first bite. Do not snack in between.
HbA1c: No fasting required. Can be done at any time.
