    This is because urea is readily reabsorbed by the kidneys while creatinine is not. In congestive heart failure (a cause of pre-renal azotemia) or any other condition that causes poor perfusion of kidneys, the sluggish flow of glomerular filtrate results in excessive absorption of urea and elevation of its value in blood. Creatinine, however, is ...
