Table 2.

Creatinine clearance following the 8-hour urine collections.

Hospital daya	Urine creatinine (mg/dL)	Serum creatinine (mg/dL)	Urine volume (mL)	Collection duration (hours)	Urine creatinine clearanceb (mL/min)
10	24	0.2	714	8	179
14	10	0.2	2132	8	222

^aHospital day 1 reflects the day of transfer from the outside facility to our center.

^bCreatinine clearance (mL/min) = [urine creatinine × volume (in mL)]/[serum creatinine × (time (in hours) ∗ 60)].
