Fasting, post-meal and random readings use different interpretation thresholds. Diagnosis requires qualified clinical assessment.

Convert your baseline first
For glucose, mmol/L = mg/dL ÷ 18.0182. To convert back, mg/dL = mmol/L × 18.0182. This calculator applies those conversions locally in your browser.
Glucose normally rises after eating, so a 2-hour post-meal reading is interpreted with higher thresholds than a fasting reading. Use the context that matches how the sample was taken.
No. It converts units and shows common reference bands only. Diagnosis requires proper testing, repeat confirmation when appropriate, symptoms, medications and clinical review.
Results are unit conversions and general range indicators generated locally in your browser. They are for informational purposes only, not medical advice, diagnosis or treatment. Blood glucose targets vary by person, pregnancy status, medications, diabetes type and clinical plan. Very low readings, very high readings, symptoms, or uncertainty should be reviewed with a qualified healthcare professional. VisionVix accepts no liability for decisions based on this output.
