[Laboratory tests in acute renal failure].
This review is focused on the roles of laboratory test in acute renal failure (ARF). The roles of the laboratory test changes along with the alterations in clinical features and with the advances of treatment. Recent acute renal failure is characterized by the following three features: most of the ARF develops in hospitals, the frequency of nonoliguric ARF is increasing, and the association of other organ failure such as heart failure, liver failure or respiratory failure, increases the mortality rate. Hemodialysis is instituted in the early phase of ARF to enable the supply of enough nutriments and drugs. These features of recent ARF increases the importance of the frequent analysis of plasma creatinine in patients, who are at risk for ARF, to diagnose ARF at the onset. After the development of ARF, laboratory tests for the evaluation of other organ function is repeated. The development of new drugs increases the incidence of interstitial nephritis, and the advances in the therapeutic approach on systemic diseases (such as SLE or PN), which frequently develop ARF, alter the prognosis of these diseases. Since the early diagnosis of these diseases is important, it is necessary to develop noninvasive and reliable tests for the diagnosis of these diseases.
