    The severity of chronic kidney disease (CKD) is described by six stages; the most severe three are defined by the MDRD-eGFR value, and first three also depend on whether there is other evidence of kidney disease (e.g., proteinuria): 0) Normal kidney function – GFR above 90 mL/min/1.73 m 2 and no proteinuria

    prerenal disease: the physiologic response to a decrease in kidney perfusion is an increase in sodium reabsorption to control hyponatremia, often caused by volume depletion or decrease in effective circulating volume (e.g. low output heart failure). above 2% [citation needed] or 3% [2] acute tubular necrosis or other kidney damage (postrenal ...

  6. 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 as signs of damage seen in blood, urine, or imaging studies which include lab albumin/creatinine ratio (ACR) ≥ 30. [ 59 ]

  7. Filtration fraction - Wikipedia

    en.wikipedia.org/wiki/Filtration_fraction

    GFR on its own is the most common and important measure of renal function. However, in conditions such as renal artery stenosis, blood flow to the kidneys is reduced. Filtration fraction must therefore be increased in order to perform the normal functions of the kidney. Loop diuretics and thiazide diuretics decrease filtration fraction.

  9. Glomerular hyperfiltration - Wikipedia

    en.wikipedia.org/wiki/Glomerular_hyperfiltration

    The primary cause of the lack of clarity surrounding the GFR levels that indicate hyperfiltration is their strong reliance on age. [12] Glomerular hyperfiltration has traditionally been characterized as an elevated whole-kidney GFR, or a GFR greater than two standard deviations above the mean GFR of healthy individuals.
