A free water clearance of zero means the kidney is producing urine isosmotic with respect to the plasma. Values greater than zero imply that the kidney is producing dilute urine through the excretion of solute-free water. Values less than zero imply that the kidney is conserving water (likely under the influence of antidiuretic hormone, ADH ...
One of the measures of kidney function is the glomerular filtration rate (GFR). Other tests that can assess the function of the kidneys include assessment of electrolyte levels such as potassium and phosphate, assessment of acid-base status by the measurement of bicarbonate levels from a vein, and assessment of the full blood count for anaemia.
3 (i.e., bicarbonate moves from urine back into the blood). [1] The regulation of H + ions and bicarbonate HCO − 3 is determined by the concentration of the two released within the urine. [1] These mechanisms of secretion and reabsorption balance the pH of the bloodstream. [1]
If potassium is being lost through the kidneys, urine potassium will likely be high. If urine potassium is low, this suggests a non-renal cause. [7] Urinary calcium (Ca) – per day: 2.5: 6.25: mmol / 24 h: An abnormally high level is called hypercalciuria and an abnormally low rate is called hypocalciuria. 14637-3: 100 [8] 250 [8] mg / 24 ...

Trace levels of protein in the urine can be normal, [60] but high levels (proteinuria) can indicate kidney disease. [45] Most cases of proteinuria are caused by increased levels of albumin , [ 61 ] which test strips can detect relatively well; but they are markedly less sensitive to other proteins, such as Bence-Jones protein , [ 62 ] which may ...
Hyperchloremia is an electrolyte disturbance in which there is an elevated level of chloride ions in the blood. [1] The normal serum range for chloride is 96 to 106 mEq/L, [2] therefore chloride levels at or above 110 mEq/L usually indicate kidney dysfunction as it is a regulator of chloride concentration. [3]
Average urine production in adult humans is around 1.4 L (0.31 imp gal; 0.37 US gal) of urine per person per day with a normal range of 0.6 to 2.6 L (0.13 to 0.57 imp gal; 0.16 to 0.69 US gal) per person per day, produced in around 6 to 8 urinations per day depending on state of hydration, activity level, environmental factors, weight, and the ...
