Test Overview

Test Methodology


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.

Reference Range


* Reference ranges may change over time. Please refer to the original patient report when evaluating results.

Specimen Requirements


Follow directions contained in the sample kit. Collect feces from the sample collection paper or specimen caught in a clean cup or collected during routine physical exams during the visit (i.e. DRE). 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. The inoculated sample may be stored at room temperature for up to fifteen (15) days or can be refrigerated at 2-8 degrees C for up to thirty (30) days.
