A complete 24 hour urine collection and a serum sample are required to calculate the rate of creatinine clearance, a measure for approximating the glomerular filtration rate (GFR), as an assessment of the excretory function of the kidneys. It is used in situations where the eGFR (estimated glomerular filtration rate) is unreliable.
