2. Glomerular filtration rate - Wikipedia

   en.wikipedia.org/wiki/Glomerular_filtration_rate

   A major measure of kidney function is the glomerular filtration rate (GFR). 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.

3. Assessment of kidney function - Wikipedia

   en.wikipedia.org/wiki/Assessment_of_kidney_function

   The Glomerular filtration rate (GFR) is regarded as the best overall measure of the kidney's ability to carry out these numerous functions. An estimate of the GFR is used clinically to determine the degree of kidney impairment and to track the progression of the disease. The GFR, however, does not reveal the source of the kidney disease.

4. Filtration fraction - Wikipedia

   en.wikipedia.org/wiki/Filtration_fraction

   In renal physiology, the filtration fraction is the ratio of the glomerular filtration rate (GFR) over the renal plasma flow (RPF). Filtration Fraction, FF = GFR/RPF, or =. The filtration fraction, therefore, represents the proportion of the fluid reaching the kidneys that passes into the renal tubules. It is normally about 20%.

5. Fractional excretion of sodium - Wikipedia

   en.wikipedia.org/wiki/Fractional_excretion_of_sodium

   This is the numerator in the equation. The denominator is the total amount of sodium filtered by the kidneys. This is calculated by multiplying the plasma sodium concentration by the glomerular filtration rate (GFR) calculated using creatinine filtration. The flow rates then cancel out, simplifying to the standard equation: [1]

6. Kidney failure - Wikipedia

   en.wikipedia.org/wiki/Kidney_failure

   Chronic kidney failure is measured in five stages, which are calculated using the person's GFR, or glomerular filtration rate. Stage 1 CKD is mildly diminished renal function, with few overt symptoms. Stages 2 and 3 need increasing levels of supportive care from their medical providers to slow and treat their renal dysfunction.

7. Basic metabolic panel - Wikipedia

   en.wikipedia.org/wiki/Basic_metabolic_panel

   Outside the United States, blood tests made up of the majority of the same biochemical tests are called urea and electrolytes (U&E or "U and Es"), or urea, electrolytes, creatinine (UEC or EUC or CUE), and are often referred to as 'kidney function tests' as they also include a calculated estimated glomerular filtration rate. The BMP provides ...

   en.wikipedia.org/wiki/Andrew_S._Levey

   Levey is known for developing the most widely used equations to estimate GFR (renal function) globally.He pioneered work with the MDRD Study Equation, [1] led the Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI), which pooled measured kidney function CKD data from studies all over the world to develop equations to estimate kidney function from serum creatinine, cystatin C, and ...
