Calcium in urine is a vital biomarker for assessing kidney health, bone metabolism, and calcium balance. While normal levels indicate proper calcium regulation, abnormalities may signal risks for kidney stones, bone loss, or metabolic disorders. Regular monitoring and targeted interventions, such as dietary adjustments or medical treatment, can help maintain optimal calcium levels and prevent complications.
Urinary calcium testing provides valuable insights into calcium balance and metabolic health:
1. Kidney Stone Risk
- Elevated calcium in urine can indicate a predisposition to calcium oxalate or calcium phosphate kidney stones.
2. Bone Health
- High urinary calcium may signal excessive bone loss (osteoporosis or osteopenia), especially if paired with low blood calcium levels.
3. Parathyroid Function
- Parathyroid glands regulate calcium levels in the blood and urine. Abnormal urinary calcium can help diagnose conditions like hyperparathyroidism or hypoparathyroidism.
4. Diet and Absorption
- Urinary calcium levels can reflect dietary calcium intake, vitamin D levels, and gastrointestinal calcium absorption efficiency.
5. Systemic Disorders
- Persistent abnormalities in calcium excretion may point to metabolic disorders, such as sarcoidosis, Paget’s disease, or certain cancers.
