Calcium

The Calcium assay measures the concentration of calcium, an essential mineral, in the blood. This test is crucial for assessing bone health, nerve function, muscle contraction, and overall body functioning. Calcium plays a vital role in various physiological processes, including bone formation, blood clotting, and regulating heart rhythm. Elevated calcium levels, known as hypercalcemia, may indicate conditions such as hyperparathyroidism, certain cancers, or excessive intake of calcium supplements. Hypercalcemia can lead to symptoms such as excessive thirst, fatigue, kidney stones, and impaired mental function.

Conversely, low calcium levels, known as hypocalcemia, may result from conditions such as hypoparathyroidism, vitamin D deficiency, or kidney disease. Hypocalcemia can cause symptoms such as muscle cramps, numbness or tingling in the extremities, and seizures. Doctors often include calcium testing as part of routine health screenings, especially in individuals at risk of bone disorders or those experiencing symptoms suggestive of calcium imbalance. This test helps diagnose and monitor various medical conditions and guides treatment decisions to maintain optimal calcium levels in the body.
