Results. Your bone density test results are reported in two numbers: T-score and Z-score. T-score. Your T-score is your bone density compared with what is normally expected in a healthy young adult of your sex. Your T-score is the number of units — called standard deviations — that your bone density is above or below the average.
A bone mineral density (BMD) test measures calcium and other minerals in bone. Bones containing more minerals are denser, so they tend to be stronger and less likely to break. Bones can become less dense as we age or if we develop certain medical conditions.
Interpret Your Bone Density Scan Results. DEXA bone scan results scores are measured as T-scores, which is a comparison of a person’s bone density with that of a healthy 30-year-old adult. The lower bone density test results, the lower your total bone density, indicating osteopenia or osteoporosis. T-Score Bone Density Chart:
A bone density scan shows how much bone is in your hip, spine and forearm. It detects low bone density and osteoporosis. These conditions cause thinning and weakening of the bones, sometimes called “brittle bones.”
The results of your bone density test, combined with all available clinical information, including your personal preference and previous experience with medications, can help with deciding to start, continue, or change medication to make your bones stronger and reduce the risk of breaking bones.
A DXA scan (bone density test) is a quick, painless way to check your bone health. It’s similar to a regular X-ray, but measures the strength and mineral content of your bones instead of just taking pictures of them.
A bone density test can help diagnose osteopenia and osteoporosis, which decrease bone density and strength, but does not show arthritis. It is a painless procedure that takes place at a hospital, medical clinic, or outpatient imaging center.
Bone densitometry testing can find decreasing bone density and strength at a much earlier stage when treatment can be beneficial. A bone density test determines the bone mineral density (BMD). Your BMD is compared to 2 norms—healthy young adults (your T-score) and age-matched adults (your Z-score).
A bone mineral density test examines segments of your bone through X-rays to detect osteoporosis. The test is quick and painless, and it gives you a snapshot of how strong they are.
What do my DEXA scan bone density test results mean? DXA bone mineral density for different sites on the skeleton is reported as grams per centimeter squared (gm 2 ) – measuring the amount of calcium and other bone materials packed in to a segment of bone.
