 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. The reproducibility of DEXA scores is frequently reported at 1-2 percent.
