Creatinine (urine)
| Creatinine (urine) | |
| CRCL, 24CRT, CRTU, creatinine clearance | |
| Random urine sample in 20ml universal, 24hr urine collection in plain (non-acidified) bottle | |
| 72hrs | |
| Urine creatinine is used either as a marker of urine concentration in the assessment of urinary excretion of compounds (e.g. albumin creatinine ratio, etc.) or the 24hr excretion of creatinine can be used (alongside a serum creatinine taken within the collection period) to estimate glomerular filtration rate (creatinine clearance). | |
| No known interferences | |
