The principle behind this ratio is the fact that both urea BUN and creatinine are freely filtered by the glomerulus; however, urea reabsorbed by the tubules can be regulated increased or decreased whereas creatinine reabsorption remains the same minimal reabsorption. Reduced renal perfusion, e. Increased urea formation also results in an increase in the ratio, e.
In most cases of chronic renal disease the ratio remains relatively normal. A decreased ratio may be observed with liver disease and poor diet. Temporary levels that are high or low may not be a cause for concern and should be retested to confirm.
