  2. Renal clearance ratio - Wikipedia

    en.wikipedia.org/wiki/Renal_clearance_ratio

    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}}}}

  3. Assessment of kidney function - Wikipedia

    en.wikipedia.org/wiki/Assessment_of_kidney_function

    Creatinine clearance exceeds GFR due to creatinine secretion, [4] which can be blocked by cimetidine. Both GFR and C Cr may be accurately calculated by comparative measurements of substances in the blood and urine, or estimated by formulas using just a blood test result ( eGFR and eC Cr ) The results of these tests are used to assess the ...

  4. Glomerular filtration rate - Wikipedia

    en.wikipedia.org/wiki/Glomerular_filtration_rate

    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 ...

  5. Creatinine - Wikipedia

    en.wikipedia.org/wiki/Creatinine

    Therefore, creatinine concentrations in blood and urine may be used to calculate the creatinine clearance (CrCl), which correlates approximately with the glomerular filtration rate (GFR). Blood creatinine concentrations may also be used alone to calculate the estimated GFR (eGFR). The GFR is clinically important as a measurement of kidney function.

  6. Kidney failure - Wikipedia

    en.wikipedia.org/wiki/Kidney_failure

    The National Kidney Foundation offers an easy to use on-line GFR calculator [34] for anyone who is interested in knowing their glomerular filtration rate. (A serum creatinine level, a simple blood test, is needed to use the calculator.)

  8. Urine protein/creatinine ratio - Wikipedia

    en.wikipedia.org/wiki/Urine_protein/creatinine_ratio

    Urine protein/creatinine ratio is a widely used initial method to estimate daily protein excretion in urine. [1] [2] [3] Since the diagnosis and management of proteinuric renal diseases and the staging of chronic kidney disease depend on accurate identification and quantitation of proteinuria, [4] [1] the implementation of the 24-hour urine collection is the most accurate procedure in practice ...

  9. Standardized Kt/V - Wikipedia

    en.wikipedia.org/wiki/Standardized_Kt/V

    Can be applied to patients with residual renal function; it is possible to demonstrate that C o is a function of the residual kidney function and the "cleaning" provided by dialysis. The model can be applied to substances other than urea, if the clearance, K, and generation rate of the substance, ˙, are known. [2]
