Still confused about what DEXA scores mean – in simple terms?
this from the NIH. How to read DEXA reports There are step-by step directions on how to read DEXA reports in this tutorial. Checking against previous BMD results to assess if the rate of loss has slowed may show the turnaround.. see also.. Problems With DEXA Scores The reproducibility of DEXA scores is frequently reported at 1-2 percent. That 1-2 percent is the average, but the range of reproducibility can vary as much as 7 percent. Variations come from changes in machine reading (using the same machine), technologists who are doing the test, and slight changes and body positioning, all of which can affect the end results. The most frequent source of error in repeat tests is patient positioning. The technology is limited because BMD is a two-dimensional image of a three-dimensional object. A few more issues related to DEXA scores are covered in this Wikipedia article which says, inter alia, “It is important for patients to get repeat BMD measurements done on the same machine each time,
