What is the primary purpose of calcium supplements prior to a bone density exam?

The primary purpose of calcium supplements prior to a bone density exam is to help in imaging quality. Adequate calcium levels are crucial for enhancing the precision and clarity of the imaging performed during a bone density test. When calcium levels are optimal, the mineralization of the bone can be accurately assessed, which contributes to a better understanding of bone health.

Calcium itself plays an essential role in the density and structure of bones, which is why having appropriate amounts in the body can aid in the evaluation process during a bone density exam. By ensuring that the calcium levels are sufficient, clinicians are able to obtain results that truly reflect the state of the patient's bone health, leading to better diagnosis and treatment options if necessary.

While calcium does help to strengthen bones over time and is important for overall bone health, in the context of preparing for an imaging exam, optimizing imaging quality is the main objective. This prevents misleading results which could arise from either too low or excessive calcium levels at the time of testing.
