The most abundant mineral in the body is calcium. It contributes to bone growth and development, regulates muscle contraction (including heartbeats) and it plays a significant role in blood clotting.
This calcium blood test screens the level of calcium in your blood. Calcium plays a role in your overall health, including for your heart, bones, nerves, kidneys and teeth. Please note that taking medications such as lithium, antacids, diuretics and vitamin D supplements can affect the accuracy of your results.
The body gets the calcium it needs in two ways. One is by eating foods or supplements that contain calcium and the other is by drawing from calcium in the body. If not enough calcium-containing foods are consumed, over time the body removes calcium from bones which can cause osteoporosis.
The best way to get enough calcium daily is to eat a variety of healthy foods from all the different food groups. Calcium-rich foods include dairy products, dark green leafy vegetables, beans, figs, nuts and seeds). Several drinks, including soy milk and orange juice, offer calcium fortified options.
