  2. 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 ...

  3. 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}}}}

  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. Standardized Kt/V - Wikipedia

    en.wikipedia.org/wiki/Standardized_Kt/V

    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).

  6. 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 =. ...

  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 ...

  8. Body surface area - Wikipedia

    en.wikipedia.org/wiki/Body_surface_area

    There was an average BSA of 1.73 m 2 for 3,000 cancer patients from 1990 to 1998 in a European Organisation for Research and Treatment of Cancer (EORTC) database. [19] During 2005 there was an average BSA of 1.79 m 2 for 3,613 adult cancer patients in the UK. Among them the average BSA for men was 1.91 m 2 and for women was 1.71 m 2. [20]

  9. Renal physiology - Wikipedia

    en.wikipedia.org/wiki/Renal_physiology

    A simple means of estimating renal function is to measure pH, blood urea nitrogen, creatinine, and basic electrolytes (including sodium, potassium, chloride, and bicarbonate). As the kidney is the most important organ in controlling these values, any derangement in these values could suggest renal impairment.
