Abstract: The present invention relates to a a method for predicting mortality of a test patient with acute kidney injury comprising (a) detecting the expression level of the non-coding RNA (ncRNA) of SEQ ID NO: 1 in a sample obtained from said test patient with acute kidney injury, (b) comparing said expression level of the ncRNA with the expression level of this ncRNA in a sample obtained from control patients with acute kidney injury or with a predetermined standard expression level of this ncRNA which was obtained on the basis of a sample from control patients with acute kidney injury, wherein the control patients were alive at least about 4 weeks after diagnosis of the acute kidney injury, and a greater than 1.

Abstract: The invention provides a method for analysis of the status of kidney function in a sample of body fluid obtained from a patient who has not been diagnosed with acute kidney injury (AKI, also referred to as acute kidney failure) or in a sample of body fluid obtained from a patient who has been diagnosed with AKI, which analysis is suitable for evaluating the prospects for long-term survival, which method for analysis comprises or consists of determining the concentration of the microRNA-210
