Chloride (urine)

Urine_electrolyte Unit: mEq/L Urine test

Reflects chloride intake and acid-base status

Also known as: Urine Cl,UCl

Reference Ranges

Clinical Reference 80.0 – 250.0 mEq/L

Optimal Range 100.0 – 220.0 mEq/L

Follows sodium generally

Metabolic Acidosis High

Metabolic Alkalosis Low

Dehydration Low

💡 Other Maintain steady hydration; avoid excessive salt loading.

💡 Other Discuss diuretic or laxative use with your physician if chloride loss is significant.

Electrolyte Replacement Tier B May Balance

Clinical rationale; supportive electrolyte balance under medical supervision in metabolic acidosis.

PMID 38004153

Electrolyte Replacement Tier B May Correct

Clinical rationale; chloride loss via vomiting/diuretics typically corrected with isotonic saline.

PMID 38004153

What does elevated urinary chloride mean for my acid-base balance? High urinary chloride can accompany metabolic acidosis or excess salt intake.
Could my low urinary chloride relate to vomiting, diuretic use, or alkalosis? Low urinary chloride is a hallmark of chloride-responsive metabolic alkalosis.
