One Step Fecal Occult Blood (FOB) Test
Occult bleeding in the stool is traces of blood that cannot be seen with the naked eye. In the early stages of gastrointestinal diseases, such as colon or stomach cancer, enteric ulcers, polyps, ulcerative colitis, diverticulitis, and fissures, there may be no visible symptoms, only occult bleeding. The occult bleeding test is intended for self-testing and home use, but it is recommended that its results be discussed with a doctor.
Interpretation of results
POSITIVE
Two colored lines appear - in the test (T) region and in the control (C) region. This indicates a positive result for hemoglobin antigen in the sample.
NEGATIVE
Only one colored line appears in the control (C) region. No colored line appears in the test (T) region. This indicates that the hemoglobin antigen concentration in the sample is 0 or below 50 ng/ml and the result is negative.
INVALID
If no line appears in the control (C) region or appears only in the test region, the result is invalid. Repeat the test with a new device. If the result is still invalid, please contact your distributor.
Important Questions
Why take this test?
Blood in the stool may be an early sign of digestive tract disorders, such as abnormal growths (polyps) or colon cancer.
What does it mean if the test result is positive?
A positive result means that occult bleeding has been detected. This does not mean that your test is positive for cancer or another disease. If the result is positive, consult a doctor for further tests and examinations to determine the exact cause and source of the hidden blood in the stool.
My test is negative. Does this mean I don't have a bowel disease?
No. You may still have a bowel condition that you should be aware of. It is recommended to get tested again after a while if you have any doubts, because if you have polyps, they may not bleed all the time. Also, the blood may not be evenly distributed in the stool sample. Early-stage colorectal polyps may not bleed.
