  2. 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 ...

  3. Assessment of kidney function - Wikipedia

    en.wikipedia.org/wiki/Assessment_of_kidney_function

    The glomerular filtration rate (GFR) describes the volume of fluid filtered from the renal (kidney) glomerular capillaries into the Bowman's capsule per unit time. [3] Creatinine clearance (C Cr) is the volume of blood plasma that is cleared of creatinine per unit time and is a useful measure for approximating the GFR.

  4. Uremia - Wikipedia

    en.wikipedia.org/wiki/Uremia

    The principal abnormality is very low GFR (<30 mL/min). Uremia will demonstrate elevation of both urea and creatinine, likely elevated potassium, high phosphate and normal or slightly high sodium, as well as likely depressed calcium levels. As a basic work up a physician will also evaluate for anemia, and thyroid and parathyroid functions ...

  5. Creatinine - Wikipedia

    en.wikipedia.org/wiki/Creatinine

    Algorithms to estimate GFR from creatinine concentration and other parameters are discussed in the renal function article. Unfortunately, the MDRD Study equation was developed in people with chronic kidney disease, and its major limitations are imprecision and systematic underestimation of measured GFR (bias) at higher/normal values. [20]

  6. 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]

  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. Kidney dialysis - Wikipedia

    en.wikipedia.org/wiki/Kidney_dialysis

    Stage 5 chronic renal failure is reached when the glomerular filtration rate is less than 15% of the normal, creatinine clearance is less than 10 mL per minute, and uremia is present. [ 1 ] Dialysis is used as a temporary measure in either acute kidney injury or in those awaiting kidney transplant and as a permanent measure in those for whom a ...

  9. Chronic kidney disease - Wikipedia

    en.wikipedia.org/wiki/Chronic_kidney_disease

    A glomerular filtration rate (GFR) ≥ 60 mL/min/1.73 m 2 is considered normal without chronic kidney disease if there is no kidney damage present. Kidney damage is defined signs of damage seen in blood, urine, or imaging studies which includes lab albumin/creatinine ratio (ACR) ≥ 30. [59]
