Calcium (Blood Test)

A calcium blood test is a diagnostic test that measures the level of calcium in the blood. Calcium is an essential mineral that plays a vital role in various bodily functions, including bone health, muscle function, and nerve transmission.

The normal range for calcium levels in the blood is typically between 8.5 to 10.5 mg/dL. Abnormal levels of calcium in the blood can indicate underlying health conditions such as kidney disease, thyroid disorders, vitamin D deficiency, or certain cancers.

Your healthcare provider may order a calcium blood test if you are experiencing symptoms of high or low calcium levels, such as fatigue, muscle cramps, or bone pain. The test may also be ordered as part of a routine health screening or to monitor the effectiveness of treatment for certain medical conditions.

It’s important to follow any pre-test instructions provided by your test provider, such as fasting before the test or avoiding certain medications that can affect calcium levels. Results of a calcium blood test may be used to guide further testing or treatment recommendations.
