High albumin (hyperalbuminemia) is almost always caused by dehydration. In some cases of retinol ( Vitamin A ) deficiency, the albumin level can be elevated to high-normal values (e.g., 4.9 g/dL) because retinol causes cells to swell with water.
As such, in clinical applications it is necessary to adjust serum total calcium concentration upward or downward if hypoalbuminemia or hyperalbuminemia is present, respectively (measured serum total calcium decreases by 0.8 mg/dL per unit decrease in albumin concentration below 4 g/dL).
Hypoalbuminemia can be caused through a number of different mechanisms, each with the result of decreasing albumin levels. These include: 1) impaired synthesis within the liver, 2) increased utilization by tissue, 3) distributional issues, and 4) increased excretion or loss. [ 7 ]
Albumin is a family of globular proteins, the most common of which are the serum albumins.All of the proteins of the albumin family are water-soluble, moderately soluble in concentrated salt solutions, and experience heat denaturation.

Secondary causes of nephrotic syndrome have the same histologic patterns as the primary causes, though they may exhibit some differences suggesting a secondary cause, such as inclusion bodies. [24] They are usually described by the underlying cause, such as: [citation needed] Diabetic nephropathy: is a complication that occurs in some diabetics ...
In many situations, alterations in renal function (even if mild, e.g., as that caused by dehydration in a patient with diarrhea) may modify the anion gap that may be expected to arise in a particular pathological condition. [citation needed] A high anion gap indicates increased concentrations of unmeasured anions by proxy.
Causes [ edit ] Increases in certain proteins that are typically present in relatively low concentrations, such as acute phase reactants and polyclonal immunoglobulins caused by inflammation , late-stage liver disease , and infections , can result in mild hyperproteinemia.
