Test Usage

This test system is intended for the qualitative detection of fecal occult blood in feces. It is recommended for use in routine physical exams, monitor for bleeding in patients and screening for colorectal cancer or other lower GI disorders that can cause gastrointestinal bleeding (e.g., diverticulitis, polyps, and Crohn's disease). No dietary restrictions are necessary for the patient due to the detection of human hemoglobin in this assay.

Contamination from toilet water should be avoided. 1. Fill in the patient demographic information on the sampling bottle. Open the green cap by turning to the left and pulling upwards. 2. Randomly scrape the surface of the fecal sample with the sample probe. Cover the grooved portion of the sample probe completely with stool sample. 3. Close the sampling bottle by inserting the sample probe and screwing cap on tightly to the right. DO NOT reopen. Send the sample device to MLabs or instruct the patient to return it to MLabs in the laboratory mailer provided.
