LOINC Code
| LOINC code | 38263-0 | ||||
|---|---|---|---|---|---|
| name | DXA Femur [T-score] Bone density | ||||
| description | Formula Input Parameter Definitions: BMD = subject's bone mineral density (BMD), MEAN_BMD = mean BMD of reference population, and SD = standard deviation of BMD within reference population. | ||||
| status | ACTIVE | ||||
Fully-Specified Name | |||||
| component | Views for 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 | Lower extremity>Femur | ||||
| 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 | ||||

History/Usage | |||||
| first released | |||||
| last updated | 2.64 | ||||
| last change type | NAM - change to Analyte/Component | ||||
| change reason | Changed Component from "Bone density T-score" and Property from "Ratio". Changed the Method from "XR.DXA" to "DXA" for conformance with LOINC/RadLex unified model.; Updated System from "Femur" per LOINC/RadLex unified model; Updated Component from "Bone density" to "Views for bone density" based on the LOINC/Radlex unified model. | ||||
