The CSAP profile helps pinpoint the causes of gastrointestinal symptoms and chronic systemic conditions, and measures key markers of digestion, absorption and inflammation. It includes comprehensive bacteriology and yeast cultures, detection of infectious pathogens and parasites, and antimicrobial susceptibility testing to prescriptive and natural agents. This is a 2-DAY SAMPLE COLLECTION. Please note that all CSAP profiles come with the materials for 3 collection days - patients only need to use the DAY 2 AND DAY 3 BAGS for this collection.
