What does below low normal Anion gap mean?
A below low normal anion gap, also known as a negative anion gap, may indicate the presence of additional unmeasured cations in the blood, such as magnesium or calcium. This can occur in conditions like multiple myeloma or paraproteinemia, where there is an excess of positively charged proteins. It is important to further investigate the underlying cause of the negative anion gap through additional laboratory tests and clinical evaluation.
