Critically ill patients are at risk of developing a sudden decrease of kidney function which may be detected by a decrease in urine output or is diagnosed on the basis of blood tests for substances normally eliminated by the kidney, primarily creatinine.
Because it takes about 24 hours for the creatinine level to rise, even if both kidneys have ceased to function, better markers are needed.
This trial is investigating if the marker urinary dickkopf-3 (uDKK3) allows an early prediction of a sudden decrease of kidney function.
