Bing provides medical information from several trusted resources including The Mayo Clinic, The American Cancer Society, MD Consult, Gold Standard, the NIH’s NCCAM and MedlinePlus. This content offers relevant and credible information on symptoms, diagnoses and medical procedures, as well as issues related to drugs and substances, personal health and alternative medicine. When you initiate a search query, Bing provides authoritative content with a clear indicator of its source (see screenshot), which appears as the top algorithmic result when searching on this term. Clicking on the link will give you the full text of the article without ever having to leave the search page. For that same query, you’ll also find a set of Quick Tabs in the left rail which you can use to refine your search further. In this case, the Quick Tabs are for articles, symptoms, diet, etc.
