What is the target lab value for Calcium?

1. 7.0-8.0 mg/dL

2. 8.4-9.5 mg/dL

3. 9.0-10.0 mg/dL

4. 10.1-11.0 mg/dL

The correct answer is: 8.4-9.5 mg/dL

The target lab value for calcium is crucial for maintaining various physiological functions. A normal serum calcium level helps ensure the correct functioning of nerves, muscles, and bone health. The range of 8.4-9.5 mg/dL is generally accepted as the normal range for total serum calcium in adults. Adequate calcium levels are necessary to avoid complications such as bone density loss or muscle weakness, which can arise from both deficiency and excess. While other ranges may exist for specific contexts or patient populations, the established norm for calcium that aligns with the accepted medical standards falls within the range of 8.4-9.5 mg/dL. This range ensures that the body maintains optimal calcium levels to support vital functions effectively without risking hypo or hypercalcemia.
