BUN Calculation Formula

BUN (Blood Urea Nitrogen) represents the amount of nitrogen in the blood that comes from urea.

Urea (mg/dL) → BUN (mg/dL)
BUN = Urea × 0.467

BUN (mg/dL) → Urea (mg/dL)
Urea = BUN × 2.14

Urea (mmol/L) → BUN (mg/dL)
BUN = Urea × 2.802

BUN (mmol/L) → Urea (mmol/L)
Urea = BUN × 0.357
