The normal calcium (Ca) blood range for adults is typically 8.5 to 10.2 milligrams per deciliter (mg/dL), which is equivalent to 2.15 to 2.55 millimoles per liter (mmol/L). However, it's crucial to remember that these values can vary slightly depending on the laboratory. Therefore, always refer to the reference ranges provided by the specific lab that performed your blood test.
Understanding Calcium Blood Levels
Maintaining the right level of calcium in the blood is crucial for various bodily functions, such as:
- Nerve function
- Muscle contraction
- Blood clotting
- Bone health
Factors Affecting Calcium Blood Levels
Several factors can influence blood calcium levels, including:
- Dietary intake of calcium and vitamin D
- Kidney function
- Hormonal imbalances (e.g., parathyroid hormone)
- Certain medications
Interpreting Your Results
- Hypercalcemia: A calcium level above the normal range may indicate an underlying medical condition, such as hyperparathyroidism or certain cancers.
- Hypocalcemia: A calcium level below the normal range may be due to vitamin D deficiency, kidney problems, or other conditions.
It is imperative to discuss any abnormal results with your healthcare provider, who can provide an accurate diagnosis and treatment plan based on your specific situation. Do not attempt self-diagnosis or self-medication. Remember, values from one lab should not be compared with reference ranges from another lab. Always use the reference range provided by the lab that processed your blood work.
| Unit | Normal Range |
|---|---|
| mg/dL | 8.5 - 10.2 |
| mmol/L | 2.15 - 2.55 |
