The glomerular filtration rate is the flow rate of filtered fluid through the kidney. The creatinine clearance rate (C Cr 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, [1] which can be blocked by ...
Para-aminohippurate (PAH) clearance is a method used in renal physiology to measure renal plasma flow, which is a measure of renal function. [citation needed]PAH is completely removed from blood that passes through the kidneys (PAH undergoes both glomerular filtration and tubular secretion), and therefore the rate at which the kidneys can clear PAH from the blood reflects total renal plasma flow.
Instead of equations, a nomogram can be used to easily estimate Kt/V from the URR in clinical practice. To use the nomogram, one needs to know the postdialysis weight (W) as well as the amount of weight (fluid) loss during the dialysis session (UF).
Low protein diets of <0.8 g/kg/day have shown improved CKD management with reduced serum phosphorus, serum urea nitrogen and reduced protein in the urine. [19] [20] [21] A very low protein diet (0.28 g/kg/day) is not recommended due to the possibility of malnutrition. The National Kidney Foundation’s Kidney Disease Outcomes Quality Initiative ...
It is a more expensive test than serum creatinine (around $2 or $3, compared to $0.02 to $0.15), which can be measured with a Jaffe reaction. [82] [83] [84] Reference values differ in many populations and with sex and age. Across different studies, the mean reference interval (as defined by the 5th and 95th percentile) was between 0.52 and 0.98 ...
The .38-55 Winchester / 9.6x53mmR cartridge (actually .3775 caliber), also known as the .38-55 WCF and the .38-55 Ballard, [4] is a centerfire rifle cartridge.It was based on an earlier cartridge called the .38-50 Ballard Everlasting that was introduced in 1876 by the Ballard Rifle & Cartridge Company.
Guillain–Barré syndrome (GBS) is a rapid-onset muscle weakness caused by the immune system damaging the peripheral nervous system. [3] Typically, both sides of the body are involved, and the initial symptoms are changes in sensation or pain often in the back along with muscle weakness, beginning in the feet and hands, often spreading to the arms and upper body.

Chest pain is pain or discomfort in the chest, typically the front of the chest. [1] It may be described as sharp, dull, pressure, heaviness or squeezing. [3] Associated symptoms may include pain in the shoulder, arm, upper abdomen, or jaw, along with nausea, sweating, or shortness of breath.
