StrataInterpret with insulin, timing, and assay units — not alone.

LimitsWhen not to use: mismatched sample timing. · Pitfall: nmol/L entered as ng/mL. · Renal failure raises C-peptide.

How it works

Ratio = (C-peptide ng/mL / glucose mg/dL) × 100.

Key points

  • Unit-sensitive.
  • Paired draw.
  • Next: insulin / etiology workup.

Worked calculation

The values below come from this tool's own example placeholders and are computed server-side with the formula shown on this page, so the arithmetic can be checked quickly. It demonstrates how to substitute values only — it is not clinical advice and not a real case.

Frequently asked questions

Does C-Peptide / Glucose Ratio upload patient data? Where is it calculated?
Calculation runs locally in the browser; inputs and results are not uploaded. For licensed clinicians only; interpret with history, investigations and local protocols — not a diagnosis or prescription.
How is C-Peptide / Glucose Ratio calculated in practice? Can you show a worked example?
Inputs: C-peptide 1.5 ng/mL, Plasma glucose 90 mg/dL → Result: C-pep/Glu ×100 1.67(Raw ratio: 0.0167 (ng/mL)/(mg/dL), Cue: 1–5 — intermediate teaching band)
