Preparing Confit. To make a classic duck confit, you'd first season duck legs with salt, brown sugar, garlic and fresh herbs such as thyme and other spices. Then, the duck is simmered in duck fat and water for a few hours. The water will slowly cook off while the fat remains.
Glomerular filtration rate. Glomerular filtration rate (GFR) is a test used by physicians and other medical professionals to see if the kidneys are working correctly. In basic terms, it is a measurement of how much liquid and waste is passing from the blood through the tiny filters in the kidney, called the glomeruli, and out into the urine during each minute.
Renal function, in nephrology, is an indication of the state of the kidney and its role in renal physiology. Glomerular filtration rate (GFR) describes the flow rate of filtered fluid through the kidney.Creatinine clearance rate (CCr or CrCl) is the volume of blood plasma that is cleared of creatinine per unit time and is a useful measure for approximating the GFR.Creatinine clearance exceeds GFR due to creatinine secretion, which can be blocked by cimetidine.enal function, in nephrology, is an indication of the state of the kidney and its role in renal physiology.
