Urine Electrolytes: Na, K, Cl (24-Hour Urine)
The test allows assessment of the content of main electrolytes — sodium, potassium, and chloride — in 24-hour urine. Used for diagnosing water-electrolyte balance disorders, kidney diseases, and monitoring therapy in pathological conditions.
Mechanism of abnormalities: elevation or decrease in electrolyte concentration indicates kidney function disorder, water-salt metabolism disorder, or endocrine diseases.
Recommended for:
- people with chronic kidney diseases
- with hypertension or swelling
- for monitoring diuretic therapy
- with water-electrolyte balance disorders
Biomaterial: 24-hour urine
- Collect all urine over 24 hours in a special container
- Exclude salty food and kidney-affecting medications for 24 hours (with doctor's approval)
- Maintain normal diet and activity
Medications: if taking diuretics or heart/kidney medications — inform the doctor
- Suspected kidney function disorders
- Arterial hypertension
- Swelling of various origins
- Acid-base balance disorders
- Monitoring dietary therapy and kidney disease treatment
Normal — sodium, potassium, and chloride content within reference values for 24-hour urine
Abnormality — indicates possible water-electrolyte metabolism or kidney function disorders
Which doctor to consult:
For test abnormalities, consultation with a nephrologist is recommended. The doctor evaluates laboratory results, clarifies clinical symptoms, and if needed prescribes treatment or dietary correction.
Self-treatment is not recommended!
