The normal serum sodium level is 135 to 148 mEq/L. Changes in body water and salt balance are determined/monitored by serum sodium levels.

Objectives: We compared two different methods of whole blood sodium measurement to plasma sodium measurement using samples in the profoundly hyponatremic range ...

The authors found a mean difference of 3.36 mmol/L. Some studies included patients with hyponatremia or hypernatremia by biochemistry autoanalyzer; however, ...

Plasma sodium levels did not change till 48hours in samples at 2 to 40C whereas changes were seen from 24hours in samples at room temperature.

A reduced plasma sodium concentration is called hyponatremia. Pseudohyponatremia is an artefact; measured serum sodium is reduced but actual plasma sodium is ...

11 сент. 2018 г. · Measurement of serum sodium is routine in assessing electrolyte, acid-base, and water balance, as well as renal function.

22 нояб. 2004 г. · These studies demonstrate that an increase or a decrease in salt intake causes changes in plasma sodium. Small changes in plasma sodium alter extracellular ...

18 окт. 2022 г. · “If it's serum, you have allowed that sample to clot.” This measures the sodium activity in an aqueous solution of diluted plasma or serum (mmol ...

2 июн. 2022 г. · A sodium blood test measures the level of sodium in your blood. Abnormal sodium levels may indicate a kidney problem or other disorder.

Indirect ISE sodium measurement can give rise to spuriously decreased serum/plasma sodium concentration (pseudohyponatremia) if lipids and/or protein are ...
