LOINC Code


LOINC code38267-1
nameDXA Lumbar spine [T-score] Bone density
descriptionFormula 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.

Fully-Specified Name

componentViews for bone density
propertyTscore  =  T Score
timePt  =  Point in time:  To identify measures at a point in time. This is a synonym for “spot” or “random” as applied to urine measurements.
systemAbdomen>Spine.lumbar
scaleQn  =  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
