How this urea conversion is calculated

General formula: mg/dL ÷ 6 = mmol/L

  • 1. Start with the value in mg/dL: 4.
  • 2. Divide by the analyte-specific factor: 4 ÷ 6.
  • 3. Result in mmol/L: ≈ 1.4285714285714286.

Tips and important notes for urea

  • Urea is produced when the body breaks down protein and is cleared by the kidneys.
  • High urea can reflect kidney impairment, dehydration, high protein intake, or bleeding in the gut.
  • Different labs may report either urea or urea nitrogen; they use different conversion factors.
