Calcium is one of the most important minerals in your body. You need calcium for healthy bones and teeth. Calcium is also essential for the proper functioning of your nerves, muscles, and heart.
A calcium blood test measures the amount of calcium in your blood. While about 99% of your body’s calcium is stored in your bones, the remaining 1% flows in the blood. If there is too much or too little calcium in the blood, it may be a sign of a range of health issues such as bone disease, thyroid disease, kidney disease, or other medical conditions.
There are two types of calcium blood tests:
Total calcium: measures the calcium attached to specific proteins in your blood and is often part of a routine screening test called a basic metabolic panel. This test measures different minerals and other substances in the blood.
Ionized calcium: measures the calcium that is unattached or “free” from these proteins.
A medical professional will carry out a thorough history and physical examination, asking the patient about the frequency of urination and other symptoms. They may also ask you to undergo a number of tests such as urine analysis, ultrasounds, X-ray, STI tests or neurological tests.

Certain medications may impact the results of the test, and you should consult your doctor if you are taking any medications.
Results usually take several days up to one week to arrive, depending on the size of the laboratory where the test is completed. Your doctor will receive the results from this test, interpret them, determine what the next steps are, and relay all of this information to you.
