pseudohyponatremia

 [soo″do-hi″po-nah-tre´me-ah]

pseudohyponatremia

Spuriously low sodium levels due to either
1. Intrinsic properties of a Pt sample–eg, hyperglycemia or hyperproteinemia–displacement of plasma water or due to the cationic nature of monoclonal proteins which bind sodium, hyperlipidemia or hyperviscosity or.
2. Analytic factors, which occur when preparing samples for flame photometry or indirect potentiometry Management Both respond to vitamin 1,25–OH2D3.
