Traditional diagnosis is based on symptoms. But uncovering the underlying causes of symptoms opens a world of preventative medicine that can better the lives of all. DirectLabs® offers tests from several different specialty labs for those who are interested in going beyond standard blood tests. In many cases, hair, saliva, urine and stool can provide invaluable in-depth information. For instance, one specialty lab can test hair samples for heavy metals such as mercury, which is an indicator of the presence and severity of autism.
