Urine Calcium, 24-Hour
The test allows determining the calcium level in urine — an important element for normal bone, muscle, and nervous system function. Used for assessing mineral metabolism, kidney function, and detecting calcium metabolism disorders.
Mechanism of abnormalities: elevated urinary calcium may indicate excessive calcium intake, hyperparathyroidism, increased bone tissue destruction, or kidney filtration disorder. Decrease — calcium deficiency or kidney reabsorption disorder.
Recommended for:
- people with chronic kidney diseases
- with suspected calcium metabolism disorder
- for monitoring osteoporosis or hypercalcemia therapy
- with kidney or urinary tract stones
Biomaterial: 24-hour urine
- Collect urine over 24 hours in a clean container
- Exclude high-calcium foods for 2-3 days
- Avoid intense physical exertion and stress
Medications: if taking calcium supplements or diuretics — inform the doctor
- Suspected mineral metabolism disorder
- Kidney diseases (stones, nephropathy)
- Monitoring diet and therapy in osteoporosis or hypercalcemia
- Muscle cramps, bone pain, or frequent fractures
Normal — 24-hour urine calcium level within reference values
Abnormality — requires physician assessment to determine the cause and choose further tactics
Which doctor to consult:
For test abnormalities, consultation with a general practitioner or nephrologist is recommended. The doctor evaluates laboratory results, correlates them with the clinical picture, and if needed prescribes treatment or additional examinations.
Self-treatment is not recommended!
