Common questions
What does chloride tell us?
Chloride works closely with sodium to keep your body's fluids and acid-base balance in check. Abnormal levels can point to dehydration, kidney issues, or acid-base problems.
Is chloride tested on its own?
It's usually measured as part of an electrolyte panel rather than alone, since the electrolytes are best interpreted together.
