Bone Density Test

Bone is a living tissue that is constantly renewed through a process in which old bone is removed and replaced by new bone. Cells called osteoclasts erode the bone, creating small cavities; bone-forming cells called osteoblasts then fill in the cavities with new bone. This is nature’s way of restoring bones and keeping them healthy.

In younger people with healthy bones, the osteoclasts and osteoblasts work together, maintaining healthy bones. However, after our mid-30s the process is not as efficient, and we begin to gradually lose bone. In someone with osteoporosis, bone loss occurs more rapidly, causing the bones to become thinner and weaker over time. If you have osteoporosis, you have already lost a significant amount of bone and may continue to do so unless you receive medication.

A bone density test is used to determine if you have osteoporosis — a disease that causes bones to become more fragile and more likely to break.

In the past, osteoporosis could be detected only after you broke a bone. By that time, however, your bones could be quite weak. A bone density test enhances the accuracy of calculating your future risk of breaking bones.

A bone density test uses X-rays to measure how many grams of calcium and other bone minerals are packed into a segment of bone. The bones that are most commonly tested are in the spine, hip and forearm.

Bone Density Testing is provided as part of our Elite Wellness Evaluation.
