Which of T-scores indicates osteoporosis?

A T-score of -2.5 or lower indicates osteoporosis. The T-score is a comparison of a person's bone density to that of a healthy 30-year-old adult of the same sex. A T-score between -1.0 and -2.5 indicates osteopenia, which is a precursor to osteoporosis. Monitoring and treatment are important for individuals with T-scores in these ranges to prevent fractures and further bone loss.
