Today, the Association for Diagnostics & Laboratory Medicine (ADLM, formerly AACC) released the results of a survey that ADLM conducted to determine how the Food and Drug Administration’s (FDA’s) final laboratory developed tests rule will impact patient access to essential tests. The survey found that, in spite of certain tests being exempt from the rule, it will still force many laboratories, particularly those in hospitals, to discontinue critical tests, including those needed to identify prescription and illegal drug use.
