How do you read a bone density test in Canada?
Below normal is always indicated with a minus (-) sign. A T-score below 2.5 SDs indicates osteoporosis and a score between 1 and 2.5 SDs indicates “osteopenia” or low bone density. Normal bone density is no more than 1 SD below the young adult normal value.
What is a serious bone density score?
A T-score within 1 SD (+1 or -1) of the young adult mean indicates normal bone density. A T-score of 1 to 2.5 SD below the young adult mean (-1 to -2.5 SD) indicates low bone mass. A T-score of 2.5 SD or more below the young adult mean (more than -2.5 SD) indicates the presence of osteoporosis.
What bone percentage should I have?
Bone content is the percentage of bone mineral as compared to total body weight. The average bone content for adults is 3-5%. This measurement is good to keep track over a long period of time as bone mass can decline slowly with age.
What is osteoporosis score?
Osteoporosis — People with osteoporosis have a T-score of -2.5 or less. Larger numbers (eg, -3.0) indicate lower bone density because this is a negative number. The lower the bone density, the greater the risk of fracture.
What are the T-score and Z-score on a bone density scan?
DEXA scores are reported as “T-scores” and “Z-scores.” The T-score is a comparison of a person’s bone density with that of a healthy 30-year-old of the same sex. The Z-score is a comparison of a person’s bone density with that of an average person of the same age and sex.
What does a bone density score tell you?
Identify decreases in bone density before you break a bone
What is a normal bone density score?
• If your T-score is –1 or greater: your bone density is considered normal. • If your T-score is between –1 and –2.5: you have low bone density, known as osteopenia, but not osteoporosis. • If your T-score is –2.5 or less: you have osteoporosis, even if you haven’t yet broken a bone.
