Gastrointestinal Diagnostics

The balance of microbes within the gastrointestinal track is critical to the digestive and overall health of a patient. Often viral infection and bacterial pathogen colonization are the main cause of acute gastroenteritis and infectious diarrhea, including Enterohemorrhagic E. coli, Shigella and C. difficil.
