Total Calcium
Total blood calcium shows the amount of calcium circulating in the body, including protein-bound and free ions. The test helps assess bone system status, mineral metabolism, and heart, muscle, and nervous system function.
The test helps:
- Detect calcium deficiency or excess
- Assess bone function and mineralization
- Diagnose thyroid and parathyroid gland disorders
- Monitor treatment of bone diseases and calcium metabolism
- Detect causes of cramps, muscle spasms, weakness
Biomaterial: Venous blood
- Submit fasting (8-12 hours without food)
- Avoid alcohol for 24 hours
- Avoid intense physical exertion before submission
- Suspected calcium deficiency or excess
- Osteoporosis, rickets
- Kidney, thyroid, or parathyroid diseases
- Symptoms: cramps, muscle weakness, limb numbness
- Monitoring calcium or vitamin D therapy
Elevated calcium — hypercalcemia, parathyroid disease, excessive calcium intake
Decreased calcium — hypocalcemia, vitamin D deficiency, kidney disease, rickets, osteoporosis
