Should a low reading of antion gap pperson need to have another blood test, or further consultation.

Hi
Thanks for writing to the forum!
“The average anion gap for healthy adults is 8-12 mEq/L. Unlike a high anion gap, obtaining a low anion gap is relatively rare. One of the most common causes of a low anion gap is a low albumin level (which constitutes ~80% of the unmeasured anions). Correspondingly, an increase in the number of cations, either organic (eg, paraproteins as in multiple myeloma) or inorganic (bromide, lithium, Iodine or polymyxin B) can lead to low anion gap values. A decreased anion gap is also seen in multiple myeloma where the increased negatively-charged immunoglobulins interact with and bind cations in the blood.”

Hope this helps. Please let me know if there is any thing else and do keep me posted. Take care!
