A 67-year-old female asked:
why would a bone density of 0.675 at left hip result in a t score of -2.2 but a bone density of 0.681 at lumbar spine result in a t score of -3.3 for female age 67. are the t scores here accurate?

T score : T -score reflects bone density compared to a 30 yo. Calculated from lots of data .The divergence defines low bone density/osteoporosis- and fracture risk. The Z- score 0.675/ 0.681 compares your bone density to other 67 year olds, but other 67 year old fracture easily. https://americanbonehealth.org/bone-density/understanding-the-bone-density-t-score-and-z-score/
