Beverages are provided and administered for producing LIS samples containing cells exfoliated from throughout the gut in sufficient numbers and free of interfering substances such as formed fecal particles fo r chemical assays and biologic assays for nucleic acid sequence information, and medical diagnosis. A kit is also provided for use by patien ts without assistance to produce a LIS sample suitable for analysis. A collection kit employs a sequence of the beverages and other ingested substances to produce preserved cells for medical diagnosis, allowing cytologic analysis of the LIS for diagnosis of foregut a nd hindgut disease. A preliminary cathartic lavage is used to cleanse a patient's digestive tract; at least one stool induced by the preliminary cathartic lavage is collected; and a final cathartic lavage is used to exfoliate and preserve cells from a patient's digestive tract. Time release capsules containing a cathartic medicament can also be used after completing preliminary lavage administration. The kit also provid es apparatus for collection, sealing, and packing of the collected LIS specimen for analysis.
