  • Publication number: 20200271669
    Abstract: It is an object of the present invention to provide a combination of a functional assessment of renal function together with biomarker results in order to improve assessment of patient at risk of, or having, an acute kidney injury. A loop diuretic such as furosemide inhibits luminal active chloride transport throughout the thick ascending limb of Henle, thereby preventing sodium reabsorption and resulting in natriuresis and increased urine flow. Loop diuretic-induced increases in urine output might be a method to assess the integrity of the renal tubular function in the setting of early AM, and so a kidney's response, or lack thereof, to a diuretic challenge as a clinical assessment of tubular function can identify patients with severe tubular injury before it is clinically apparent (e.g. a rise in creatinine).
