  • Your value of 5.50 mmol/L equals 99.1 mg/dL.
  • Clinical category: Normal fasting (3.9-5.5 mmol/L / 70-99 mg/dL).
  • These categories are based on fasting measurements. Post-meal (postprandial) targets differ: normal is below 7.8 mmol/L (140 mg/dL) two hours after eating.
  • A single reading does not diagnose diabetes. Diagnosis requires two confirmatory fasting tests, an OGTT, or HbA1c above 48 mmol/mol (6.5%).

Next stepAlways interpret glucose readings with your healthcare provider and consider fasting state, time of day, and recent meals.
