LOINC Code
| LOINC code | 77454-7 | ||
|---|---|---|---|
| name | Deprecated Hindfoot and Midfoot DXA [T-score] Bone density | ||
| description | T-score = (BMD - MEAN_BMD) / SD, where BMD = subject's bone mineral density (BMD), MEAN_BMD = mean BMD of reference population, and SD = standard deviation of BMD within reference population. | ||
| status | DEPRECATED | ||
| status reason | Erroneous - DXA measurements are just of the calcaneus bone, not of the broader region. | ||

Fully-Specified Name | |||
| component | Bone density | ||
| property | Tscore = T Score | ||
| time | Pt = Point in time: To identify measures at a point in time. This is a synonym for “spot” or “random” as applied to urine measurements. | ||
| system | Hindfoot+Midfoot | ||
| scale | Qn = Quantitative: The result of the test is a numeric value that relates to a continuous numeric scale. Reported either as an integer, a ratio, a real number, or a range. The test result value may optionally contain a relational operator from the set {<=, <, >, >=}. Valid values for a quantitative test are of the form "7", "-7", "7.4", "-7.4", "7.8912", "0.125", "<10", "<10.15", ">12000", 1-10, 1:256 | ||
