Renal Function
Kidney function can be difficult to assess, and we use a variety of measured and derived values to estimate glomerular filtration rate.
Urea
Measures the entire urea molecule
Affected by fluid status and protein metabolism
Blood Urea Nitrogen (BUN)
Measures the nitrogen content in urea
Creatinine
Affected by muscle mass / myopathy
Urea:Creatinine Ratio
Elevated UCR is suggestive of a prerenal cause of AKI
