alexxa, read the chapter on DEXA results in the Great Bones book. This will help you prepare questions for your dexa review with your PCP.

My PCP never caught an issue with my DEXA detail around L1-4 vertebrate. My PCP may have only read the summary report vs looking at the detail x rays. If you can, get a detailed copy of your DEXA from whomever performed the test, read McCormick's chapter on DEXA, and formulate your questions for the PCP.
