[Pseudohyponatremia and anion gap changes in multiple myeloma]
Summary
Pseudo-hyponatremia, a rare condition, can cause falsely low plasma sodium levels. This case highlights how measurement methods impact results in multiple myeloma patients.
Area of Science:
- Clinical Medicine
- Biochemistry
Background:
- Pseudo-hyponatremia is characterized by decreased plasma sodium with normal or increased effective plasma osmolarity.
- It is a rare condition that can be mistaken for true hyponatremia.
