What Is a Serum Calcium Test?
A serum calcium test measures the amount of calcium in your blood. Doctors often call it a blood calcium level test. Calcium is a mineral your body needs for healthy bones, teeth, nerves, and muscles. This test helps check if your calcium levels are normal. It is a simple blood test done in many clinics and hospitals.
Why Is a Serum Calcium Test Done?
Doctors order a serum calcium test for several reasons. First, it helps find problems with your bones, kidneys, or parathyroid glands. These organs help control calcium in your body. Also, the test can help check for diseases that affect calcium levels, like certain cancers or vitamin D problems. Sometimes, doctors use this test to monitor people taking medicines that change calcium levels. In short, the test is important for finding and managing many health issues.
How Is the Test Performed?
The serum calcium test is quick and simple. A nurse or technician will draw a small amount of blood from your arm. Usually, you do not need to do much to prepare. However, some medicines can affect your results. Therefore, tell your doctor about all medicines and supplements you take. Sometimes, you may need to stop eating or drinking for a few hours before the test. Your doctor will give you clear instructions if needed.
What Do the Results Mean?
The meaning of serum calcium results depends on your age, health, and lab standards. Normal blood calcium levels for adults are usually between 8.5 and 10.2 milligrams per deciliter (mg/dL). However, these numbers may vary slightly by lab. If your calcium level is outside this range, your doctor will look for possible causes.
Sometimes, abnormal results do not mean you have a serious problem. For example, mild changes can happen from diet or temporary illness. Still, your doctor may order more tests to find the cause.
Common Causes of Abnormal Calcium Levels
Many things can cause high or low blood calcium. For example, high calcium may result from:

Rarely, the area may get sore or infected. However, these problems are uncommon. If you have bleeding problems or take blood thinners, tell your doctor before the test.

If your test shows abnormal calcium levels, do not panic. Many causes are mild or easy to treat. However, you should talk to your doctor if you have symptoms like:
