What is a bone mineral density test? A bone mineral density (BMD) test measures calcium and other minerals in bone.

When too much bone is lost, osteoporosis can develop.

¿Qué es una prueba de densidad mineral ósea? Una prueba de densidad mineral ósea mide el calcio y otros minerales en los huesos. Los huesos que contienen más minerales son más densos, por lo que tienden a ser más fuertes y menos propensos a quebrarse.
