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.
