Gastrointestinal complaints are among the most common reasons that patients seek medical care. Symptoms associated with GI disorders include persistent diarrhea, constipation, bloating, indigestion, irritable bowel syndrome and malabsorption. The Comprehensive Stool Analysis is a simple stool test that can help assess digestive and absorptive functions, the presence of opportunistic pathogens and to monitor the efficacy of therapeutic remediation of GI disorders. Antimicrobial susceptibility testing to prescriptive and natural agents is also performed for appropriate bacterial and fungal species at no additional charge.
