How it works

The final ratio is calculated by dividing BUN in mg/dL by creatinine in mg/dL. — BUN-to-Creatinine Ratio: Renal Physiology, Lab Methods, and Clinical Interpretation
Patients should fast for 8–12 hours before diagnostic BUN-to-creatinine ratio testing. — BUN-to-Creatinine Ratio: Renal Physiology, Lab Methods, and Clinical Interpretation
Both BUN and creatinine should be measured from serum rather than plasma. — BUN-to-Creatinine Ratio: Renal Physiology, Lab Methods, and Clinical Interpretation
Hemoglobin contamination should be avoided because it can interfere with colorimetric absorbance readings. — BUN-to-Creatinine Ratio: Renal Physiology, Lab Methods, and Clinical Interpretation
The Dieulafoy Reaction and Astra System are BUN assay methods, and both report BUN in mg/dL. — BUN-to-Creatinine Ratio: Renal Physiology, Lab Methods, and Clinical Interpretation
The Jaffe Reaction and enzymatic procedure are creatinine assay methods, and both report creatinine in mg/dL. — BUN-to-Creatinine Ratio: Renal Physiology, Lab Methods, and Clinical Interpretation
