Calcium (Osteoporosis)

Calcium is an important factor in our overall health, and almost every cell in our body uses calcium. The nervous system, muscles, heart and bone are a few areas where calcium is used by the body. We receive calcium from the foods we consume and through vitamins and supplements. PTH is an essential test that will indicate if the body is releasing calcium into the blood stream. It also helps to trigger Vitamin D which will increase calcium absorption. Thank you for browsing our selection of Calcium (Osteoporosis) blood tests and panels.
