Calcium
The Calcium Test measures the level of calcium in the blood to evaluate bone health, nerve function, and metabolic balance.About Test
The Calcium Blood Test measures the amount of calcium present in your blood. Calcium is an essential mineral required for maintaining strong bones and teeth. Most of the calcium in the body is stored in bones, while a small portion circulates in the blood.
Calcium plays an important role in several vital body functions including muscle contraction, nerve signaling, hormone release, and proper heart function. Maintaining balanced calcium levels in the blood is necessary for overall health.
Abnormal calcium levels may indicate conditions related to the bones, kidneys, thyroid gland, or parathyroid glands. A calcium test helps doctors evaluate bone health, detect metabolic disorders, and monitor certain medical conditions.
This test is often performed as part of routine health check-ups or to investigate symptoms related to calcium imbalance.
Why This Test
The Calcium Blood Test helps evaluate calcium balance in the body and detect conditions related to abnormal calcium levels.
Evaluate Bone Health
Calcium is a major component of bones. The test helps detect bone disorders such as osteoporosis or other conditions affecting bone strength.
Assess Kidney Function
The kidneys help regulate calcium levels in the body. Abnormal calcium levels may indicate kidney-related disorders.
Check Parathyroid and Thyroid Function
The parathyroid glands control calcium balance. This test helps detect disorders of the parathyroid or thyroid glands.
Detect Metabolic Disorders
The test may help diagnose metabolic conditions that affect calcium levels in the blood.
Investigate Symptoms
Doctors may recommend this test if you experience symptoms such as muscle cramps, fatigue, abnormal heartbeat, numbness, or bone weakness.
Who Should Take
