Can blood calcium levels from a blood test can determine if you have osteoporosis?

Blood calcium levels alone cannot definitively determine if you have osteoporosis. Osteoporosis is primarily diagnosed through bone density tests, such as a DEXA scan, which measure bone mineral density. While calcium levels can indicate overall bone health, osteoporosis involves complex factors including bone density, structure, and risk of fractures rather than just calcium levels in the blood. Therefore, a comprehensive assessment is necessary for a proper diagnosis.
