Her cultures on September 21st showed moderate growth of gram positive bacilli and gram positive cocci with some gram negative bacilli and yeast cells. Therefore, throughout her ICU stay, her body was continuing to fight infection, and so her white blood cell count was often elevated. The two biggest laboratory indicators of acute and chronic renal failure are elevated urea and creatinine levels.14 Mrs. E’s urea levels were high 100 percent of the time she was in the ICU.
Normal urea concentration is 2.9 to 7.5 mmol/L, according to CVH accepted normal values. Mrs. E’s lowest urea value was 10.1 mmol/L on September 19th and her highest concentration was 66.5 mmol/L on October 3rd. Similarly, Mrs. E’s creatinine values were elevated for 95 percent of her stay in hospital. Her lowest creatinine concentration was 94 µmol/L on September 20th and the highest concentration recorded was 348 µmol/L on September 14th. Normal concentration of creatinine in the blood is 58 – 110 µmol/L. A third indicator of kidney function is hypoalbuminemia, as it can be a feature of

nephrotic syndrome (Finkle, 2004). Mrs. E’s albumin level was low for 100 percent
