Do Not Estimate, When You Can Measure.

The article discusses the use of estimated glomerular filtration rate (GFR) in the treatment of critically ill patients. The authors argue that GFR estimations based on plasma levels are unreliable and suggest using 24-hour urine collections and creatinine plasma levels to measure GFR instead. They also mention that therapeutic drug monitoring is a more reliable method for dosing drugs based on renal function. The authors acknowledge the need for further research in developing equitable approaches to kidney function assessment in critical care practice. [Extracted from the article]
