Genetic tests may come from a medical source, genetic counselor or direct-to-consumer
            (DTC) provider.
         
         There is currently little regulation and oversight of DTC testing, leading to concerns
            about such tests’ accuracy, reliability, and clinical relevance. Another concern about
            DTC tests is the potential “chain of custody” issue. By “chain of custody,” we mean
            that generally, with DTC tests, there is no way to ensure a given result is from any
            particular individual. For these reasons, DTC test results cannot establish a medically
            determinable impairment (MDI) even if an acceptable medical source (AMS) was involved
            with the testing or adopted the findings. Nevertheless, these tests can help corroborate
            allegations and other findings when consistent with other evidence in the file.
