This interferes with the measurement of serum sodium concentration by certain methods, leading to an erroneously low measurement of sodium, or pseudohyponatremia. The methods affected are the flame-photometric and indirect (but not direct) ion-selective electrode assays.
But, in patients with severe endogenous or exogenous hypertriglyceridemia and in patients with high plasma protein concentration (usually due to paraproteinemia), water portion of plasma is replaced with either lipid or protein causing falsely low electrolyte value (pseudohyponatremia). [4]
The causes of hyponatremia are typically classified by a person's body fluid status into low volume, normal volume, or high volume. [4] Low volume hyponatremia can occur from diarrhea, vomiting, diuretics, and sweating. [4] Normal volume hyponatremia is divided into cases with dilute urine and concentrated urine. [4]
Common causes in pediatric patients may be diarrheal illness, frequent feedings with dilute formula, water intoxication via excessive consumption, and enemas. [3] Pseudohyponatremia is a false low sodium reading that can be caused by high levels of fats or proteins in the blood.
It happens sometimes to even the most productive of us: 3 p.m. rolls around, and suddenly our eyes feel heavy and our bodies crave some couch time. Unfortunately, this afternoon slump is rarely ...
Hypoosmolar hyponatremia is a condition where hyponatremia is associated with a low plasma osmolality. [1] The term "hypotonic hyponatremia" is also sometimes used.[2]When the plasma osmolarity is low, the extracellular fluid volume status may be in one of three states: low volume, normal volume, or high volume.
“If the president were to defy an order, it would cause a political firestorm,” Cole said. “And he knows that, and he’s therefore very unlikely to do it.” ...
Causes of Prediabetes. Prediabetes happens when your body stops using insulin as efficiently as it should. Insulin is a hormone produced by the pancreas. It works like a key, opening the door to ...
