Calcium Test

$79

Balancing calcium blood levels is important for more than strong bones.

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.

Thinking about long term bone health?

If you have low calcium levels, either from not eating enough or from poor absorption, your body takes the calcium it needs from your bones, a process that can eventually lead to weaker bones.¹

Are your levels balanced?

High blood levels of serum calcium (hypercalcemia) don’t usually cause symptoms, but when significantly elevated, they may cause weakness and fatigue, nausea or vomiting, constipation or loss of appetite.

Low calcium levels (hypocalcemia) can cause dry skin, coarse hair and nails that break easily, muscle cramps or weakness, numbness or tingling in fingers, abnormal heart rate, poor appetite.²^,⁴

Is age a factor?

For most people, calcium deficiency increases along with age.

For most people, calcium deficiency increases along with age.

This may be due to a variety of factors, including:¹

Medications that may decrease calcium absorption
Hormonal changes, especially in women during menopause and postmenopausal
Certain genetic factors
