Diabetes
PPBS
Also known as: Post Prandial Blood Sugar, PP Glucose
What it means
Blood sugar 2 hours after a meal. Shows how well your body handles food; elevated PPBS with normal fasting is an early diabetes clue.
Typical normal range
Normal: <140 mg/dL · Pre-diabetes: 140–199 · Diabetes: ≥200
Reference ranges vary by lab, age, sex, and pregnancy. Always check the range on your own report.
