*The usual marker for this entity is elevated serum urea and/or elevated serum creatinine PLUS an elevated urea:creatinine ratio. The normal value of this ratio (in the units used here) is 44, so a ratio > 66 is suggestive of a pre-renal state. While pre-renal patients are usually intravascularly depleted, this is not universally the case; any situation in which renal perfusion is reduced can give a pre-renal state, even without volume depletion. An example is bilateral renal artery stenosis. | *The usual marker for this entity is elevated serum urea and/or elevated serum creatinine PLUS an elevated urea:creatinine ratio.
