Calcium is the most abundant mineral in the body and contributes to the growth and development of bones, regulates muscle contraction (including the beating of your heart), and plays a significant role in blood clotting.
Calcium is found in a variety of foods including milk, cheese, yogurt, beans, figs, broccoli, spinach, nuts, and seeds. Several drinks, including soy milk and orange juice, offer versions fortified with calcium.
This test measures the total amount of calcium in the blood to screen for, diagnose, and monitor a range of health conditions relating to the bones, heart, nerves, kidneys, and teeth. It’s important to note that taking medications such as lithium, antacids, diuretics, and vitamin D supplements can affect the accuracy of your results.
No special preparation. However, certain medications, multivitamins, and supplements can interfere with this test. See test description.
