A commonly used surrogate marker for the estimation of creatinine clearance is the Cockcroft–Gault (CG) formula, which in turn estimates GFR in ml/min: [21] It is named after the scientists, the asthmologist Donald William Cockcroft (b. 1946) and the nephrologist Matthew Henry Gault (1925–2003), who first published the formula in 1976, and ...
The renal clearance ratio or fractional excretion is a relative measure of the speed at which a constituent of urine passes through the kidneys. [ 1 ] [ 2 ] It is defined by following equation: c l e a r a n c e r a t i o o f X = C x C i n {\displaystyle clearance\ ratio\ of\ X={\frac {C_{x}}{C_{in}}}}
The normal range of GFR, adjusted for body surface area, is 100–130 average 125 (mL/min)/(1.73 m 2) in men and 90–120 (mL/min)/(1.73 m 2) in women younger than the age of 40. In children, GFR measured by inulin clearance is 110 (mL/min)/(1.73 m 2 ) until 2 years of age in both sexes, and then it progressively decreases.
Therefore, the urinary and plasma concentrations of sodium must be compared to get an accurate picture of kidney clearance. In clinical use, the fractional excretion of sodium can be calculated as part of the evaluation of acute kidney failure in order to determine if hypovolemia or decreased effective circulating plasma volume is a contributor ...
Kt/V and standardized Kt/V are not the same. Kt/V is a ratio of the pre- and post-dialysis urea concentrations. Standardized Kt/V is an equivalent clearance defined by the initial urea concentration (compare equation 8 and equation 10).

One drink is defined as 1.5 ounces of liquor, 12 ounces of beer or 5 ounces of wine. Taub-Dix points out that alcoholic cocktails are often made with ingredients like mixers, syrups and juice drinks.
The city’s hated new congestion toll could dangerously delay FDNY response times — meaning the “difference between life and death,” unions repping thousands of Bravest warned Sunday. The ...
