This Calcium Blood Test is used to measure levels of calcium in the body by way of an accurate blood test. Calcium is essential in keeping bones and teeth healthy and plays key roles in sending nerve signals and blood clotting. Calcium deficiencies (hypocalcemia) can cause bones to become brittle and can lead to osteoporosis, cramps, dermatitis, and skeletal malformations. Dairy products are rich in calcium and, barring an allergy or intolerance, it’s important to make sure they are part of your regular diet. With our Calcium Blood Test, you can know for sure if your diet has a healthy balance of this necessary mineral.
