pseudohyponatremia

 [soo″do-hi″po-nah-tre´me-ah]
a decreased serum sodium concentration that does not correspond to a real hypotonic disorder, i.e., the serum osmolality is normal. It occurs when hyperlipemia increases the serum non-water volume or hyperproteinemia increases the serum non-sodium solute.

pseu·do·hy·po·na·tre·mi·a

(sū'dō-hī'pō-nă-trē'mē-ă),
A low serum sodium concentration due to volume displacement by massive hyperlipidemia or hyperproteinemia; also used to describe the low serum sodium concentration that may occur with high blood glucose.

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.

Severe lipaemia leads to electrolyte exclusion, resulting in falsely low sodium measurement (pseudohyponatraemia) when an indirect method, such as found in automated analysers, is used (dilutioncalculation error).
