How this urea conversion is calculated
General formula: mg/dL ÷ 6 = mmol/L
- 1. Start with the value in mg/dL: 100.
- 2. Divide by the analyte-specific factor: 100 ÷ 6.
- 3. Result in mmol/L: ≈ 35.714285714285715.

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.
