The Hem occult test, also known as the fecal occult blood test (FOBT), is a type of screening test used to detect the presence of hidden blood in the stool. It is a non-invasive procedure that can be performed at home using a kit provided by a healthcare provider. The test is commonly used to screen for colorectal cancer or other conditions that can cause bleeding in the digestive tract, such as ulcers, polyps, or hemorrhoids. It is recommended for individuals who are at average risk for colorectal cancer and who do not have any symptoms. The Hem occult test works by detecting the presence of blood in the stool, which may not be visible to the naked eye. The test kit typically contains a collection paper or brush that is used to collect a small sample of stool.
The test kit typically contains a collection paper or brush that is used to collect a small sample of stool. The sample is then applied to a test card or slide, which contains a chemical that reacts with the blood. If blood is present in the stool, a color change will occur on the test card or slide.
Stool Test: Fecal Blood
Testing a stool sample can help doctors find out what's going on when someone has a problem in the stomach, intestines, rectum, or other part of the gastrointestinal (GI) system.
Unlike most other lab tests, parents might need to collect the stool (feces or poop) sample for the test (also called a fecal test). The doctor or lab will give instructions on how to do this.
What Is a Fecal Occult Blood Test?
The fecal (FEE-kul) occult blood test checks for blood in the poop.
Why Are Fecal Occult Blood Tests Done?
A fecal test can find hidden (occult) blood in the stool that can’t be seen by the naked eye. The blood may come from any part of the digestive tract, from the esophagus to the rectum and anus (where poop comes out). Sometimes, it can come from swallowed blood if a child has had bleeding from the mouth, throat, or nose.
Doctors may order a fecal occult blood test to look for blood in the poop from things such as:
- allergies or inflammation
- gastrointestinal infection caused by bacteria, viruses, or parasites
- bleeding in the GI tract from ulcers and other problems
- polyps (abnormal growths in mucous membranes, like the colon)
For a week before the test, your child may be asked to avoid some types of foods and medicines (such as aspirin and anti-inflammatory drugs like ibuprofen), and vitamin C supplements.
How Is the Test Done?
The doctor or lab technician smears some of the sample onto special paper, then puts a chemical solution called guaiac (GWY-ak) on it. If the paper turns blue, there's blood in the stool.
What if I Have Questions?
If you have questions about the fecal test or what the test results mean, talk to your doctor.
If you have questions about the fecal test or what the test results mean, talk to your doctor.
This indicates a positive result and further evaluation may be necessary, such as a colonoscopy or other diagnostic tests, to determine the cause of the bleeding. It is important to follow the instructions provided with the Hem occult test kit carefully to ensure accurate results. This may include avoiding certain foods and medications before collecting the stool sample, as they can interfere with the test. Overall, the Hem occult test is a valuable screening tool for detecting hidden blood in the stool, which can be an early sign of colorectal cancer or other gastrointestinal conditions. It is a simple and non-invasive test that can be performed at home, making it convenient for individuals to monitor their colorectal health..
