Calcium
Calcium is an essential mineral that plays a key role in bone strength, muscle contraction, nerve function, and blood clotting. The Calcium Test measures total calcium levels in the blood to help detect calcium imbalances, which can indicate underlying conditions affecting the bones, kidneys, thyroid, or parathyroid glands. This test is useful for evaluating bone health, kidney function, and metabolic disorders, as well as monitoring individuals on calcium or vitamin D supplements.

Common reasons for testing
- Bone Health Monitoring – Assesses calcium levels to help detect osteoporosis or bone metabolism disorders.
- Parathyroid Function Evaluation – Helps diagnose conditions related to parathyroid hormone regulation.
- Kidney Disease Management – Monitors calcium levels in individuals with kidney disease, as kidney function affects calcium balance.
- Unexplained Symptoms – Investigates symptoms like muscle cramps, numbness, fatigue, or abnormal heart rhythms that may be linked to calcium imbalances.
- Monitoring Calcium Supplementation – Ensures safe and effective calcium intake, especially for those taking supplements for osteoporosis or deficiency
