One Step Fecal Occult Blood (FOB) Rapid Test Cassette
FOB TEST INTENDED USE
The One-Step Fecal Occult Blood (FOB) Diagnostic Kit is a qualitative detection of human occult blood in feces forself-testing.
FOB TEST PRINCIPLE
The One-Step Fecal Occult Blood (FOB) Diagnostic Kit is an immunochromatographic sandwich method, which employ two specific monoclonal antibodies to selectively identify hemoglobin in test samples. The result is very specific, and easier to interpret than those of guaiac-based test. The sensitivity is very high with the ability to detect 200ng/ml hemoglobin in feces. In addition, the accuracy of the test is not affected by interfering substances, and dietary restriction is not necessary.
FOB TEST STORAGE
The kits should be stored at temperature 4-30°C, the sealed pouch for the duration of the shelf life (24 months). Do the test in 1 hour after open the pouch.

Negative: Only one colored band appears on the control region (C). No colored band in the test region (T).
Positive: In addition to the control band (C), a distinct colored band also appears in the test region (T).
Invalid: If no bands appear, or a test band appears without a control band, the test should be repeated using a new test device.
FOB TEST LIMITATION
1.The test is a qualitative screening assay for determination of human occult blood in feces and is not for determining quantitative concentration levels.
2.Positive result can only indicate that hemoglobin occurred in human feces. Hemorrhoids, gastric ulcer and menses bleeding or interfere by hemo urine also may cause a positive result.
3.Colonic bleeding is not caused by cancer or pathological changes before cancer totally. Please confirm the result with professional doctor.
