Kidney Function Test Values: BUN and Creatinine from Chapter 20 / Lesson 6 101K BUN and creatinine are two important test values to determine kidney function. Understand the importance of the kidneys and examine blood urea nitrogen, BUN and the liver, BUN and the kidneys, and serum creatini...
The normal range for the BUN:creatinine ratio (BCR) has not been determined for infants and children. The objectives of this study were to: (1) test the hypothesis that the BCR is higher in young children; and (2) establish normal BCR ranges for children of various ages. In this ...

An increase in BUN/Creatinine ratio can indicate fluid volume deficit. This ratio is used to evaluate kidney function, and an elevated ratio suggests that there is a higher concentration of urea (BUN) relative to creatinine in the blood. In cases of fluid volume deficit, there is a decrease...

A 70-year-old woman with a history of hypertension, diabetes and renal disease presented to the emergency department complaining of diffuse weakness for 24 hours. On examination, vital signs showed a normal temperature, pulse 100 beats/min, respiratory rate 25 breaths/min, pulse oximetry 97%, ...
Serum chemistries: pH 7.30, bicarbonate 22 mmol/L, BUN 128 mg/dL, creatinine 28.3 mg/dL, and glucose 240 mg/dL. ECG showed that absence of regular P-waves, peaked T-waves and widening of the QRS complex. The patient was treated intravenously with calcium gluconate, sodium bicarbonate, ...
