1. Determine this patient's body surface area.
2. Calculate the creatinine clearance result using the data provided (do not use age and sex).
3. Calculate the albumin excretion in milligrams per day (mg/day).
4. Calculate the albumin excretion in micrograms per minute (ug/min).
5. Calculate the urine albumin-to-creatinine ratio in micrograms albumin per milligram of creatinine (ug albumin/mg creatinine).
