2. PAH clearance - Wikipedia

   en.wikipedia.org/wiki/PAH_clearance

   Para-aminohippurate (PAH) clearance is a method used in renal physiology to measure renal plasma flow, which is a measure of renal function. [citation needed]PAH is completely removed from blood that passes through the kidneys (PAH undergoes both glomerular filtration and tubular secretion), and therefore the rate at which the kidneys can clear PAH from the blood reflects total renal plasma flow.

3. Assessment of kidney function - Wikipedia

   en.wikipedia.org/wiki/Assessment_of_kidney_function

   Blood tests are also used to assess kidney function. These include tests that are intended to directly measure the function of the kidneys, as well as tests that assess the function of the kidneys by looking for evidence of problems associated with abnormal function. One of the measures of kidney function is the glomerular filtration rate (GFR).

4. 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 ...

   Volume of blood plasma delivered to the kidney per unit time. PAH clearance is a renal analysis method used to provide an estimate. Approximately 625 ml/min. renal blood flow = (HCT is hematocrit) Volume of blood delivered to the kidney per unit time. In humans, the kidneys together receive roughly 20% of cardiac output, amounting to 1 L/min in ...

6. Aminohippuric acid - Wikipedia

   en.wikipedia.org/wiki/Aminohippuric_acid

   PAH is useful for the measurement of renal plasma flow. [1]The renal extraction ratio of PAH in a normal individual is approximately 0.92. [2] This means that unlike inulin and creatinine, which are filtered in the glomerulus and ignored by the rest of the kidney, aminohippuric acid is both filtered and secreted, being almost entirely removed from the bloodstream in a normal kidney.

7. Fractional excretion of sodium - Wikipedia

   en.wikipedia.org/wiki/Fractional_excretion_of_sodium

   Therefore, the urinary and plasma concentrations of sodium must be compared to get an accurate picture of kidney clearance. In clinical use, the fractional excretion of sodium can be calculated as part of the evaluation of acute kidney failure in order to determine if hypovolemia or decreased effective circulating plasma volume is a contributor ...
