Understanding the marker
Chloride often tracks sodium and helps maintain acid-base balance and fluid status.
Chloride is an electrolyte interpreted with sodium, potassium, kidney function and clinical context. Chloride alone does not establish an acid-base disorder; additional measurements may be required.
What does high Chloride mean?
A high chloride result can reflect a change in fluid or acid-base balance. It is interpreted with sodium, kidney function and other electrolytes rather than used alone to identify a cause.
What does low Chloride mean?
A low chloride result can reflect a change in fluid or acid-base balance. Sodium, other electrolytes, fluid losses and any medicines help explain the pattern.
