Acute kidney injury (AKI) diagnosis relies on plasma creatinine concentration (Crpl ), a relatively insensitive, surrogate biomarker of glomerular filtration rate that increases only after significant damage befalls. However, damage in different renal structures may occur without increments in Crpl , a condition known as subclinical AKI. Thus, detection of alterations in other aspects of renal function different from glomerular filtration rate must be included in an integral diagnosis of AKI. With this aim, we adapted to and validated in rats (for preclinical research) the furosemide stress test (FST), a tubular function test hitherto performed only in humans...
