Tag: Serum sodium

The normal concentration of Na+ in blood is a tightly regulated parameter, typically ranging between 135 and 145 millimoles per liter (mmol/L). This balance is critical for numerous physiological functions, including fluid balance, nerve transmission, and muscle contraction.

While over 70% of dietary sodium comes from processed foods, a high level of this crucial electrolyte in the blood is a medical condition called hypernatremia. If you've been searching "What is an elevated level of blood sodium called quizlet?", you are likely looking to understand this important health topic more deeply, a subject often covered in medical flashcard sets to aid study.

Water intoxication, also known as hyponatremia, is medically diagnosed when a blood test reveals a serum sodium concentration below 135 mEq/L. The most definitive measurement for water intoxication is therefore the precise assessment of serum sodium levels, which indicate the dilution of electrolytes in the blood.
