Duck confit recipes instruct to rinse off or wipe off of salt prior to slow cooking. I have a leg thigh left in the freezer and may try again, wiping off salt. We separated the liquid remaining after cooking from the meat and duck fat, and used the liquid to make mashed potatoes.
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.lomerular filtration rate (GFR) is equal to the Clearance Rate when any solute is freely filtered and is neither reabsorbed nor secreted by the kidneys. The rate therefore measured is the quantity of the substance in the urine that originated from a calculable volume of blood.
GFR is a calculation that determines how well the kidneys are filtering the blood. GFR detects stages of chronic kidney disease. A GFR under 60 may indicate kidney disease. The lower the GFR, the less the kidneys are functioning, states WebMD. Another test that determines kidney function is urine albumin.
