A Fecal occult blood test is a type of medical procedure used to detect hidden (occult) blood in the stool. It can help diagnose and monitor various conditions, such as gastrointestinal bleeding or colon cancer. This test requires special preparation, which includes dietary changes prior to taking it and understanding what your results mean afterwards. If you are considering this fecal occult blood test for yourself or someone else, read on to learn more about how it works and its potential risks before purchasing any testing supplies needed for this procedure.
What is a Fecal Occult Blood Test?
A fecal occult blood test (FOBT) is a medical test kit used to detect hidden blood in the stool, which can be an indicator of colorectal cancer or other digestive diseases. This article will discuss what the test measures, how it is performed, and the benefits of this test.
What Does the Test Measure?
The FOBT measures levels of hemoglobin in your stool sample. Hemoglobin is a protein found in red blood cells that carries oxygen throughout your body. If there are traces of hemoglobin present in your stool sample, it could indicate bleeding from within your gastrointestinal tract caused by polyps or tumors.
How is the Test Performed?
The FOBT involves collecting a small amount of stool on special cards provided by your doctor's office or lab test and sending them off for testing. Your doctor may also recommend you take an at-home kit that allows you to collect multiple samples over several days before mailing them back for analysis. The results typically come back within one week after collection and testing has been completed.
What are the Benefits of this Test?
The FOBT provides an effective way to screen for colorectal cancer without having to undergo more invasive procedures such as colonoscopies or sigmoidoscopies which require sedation and can cause discomfort during recovery time afterwards. Additionally, since early detection increases survival rates significantly with any type of cancer diagnosis, regular screening with an FOBT can help catch potential problems before they become serious health issues down the road if left untreated for too long.
Preparation for a Fecal Occult Blood Test
Before undergoing a fecal occult blood test, there are certain dietary and medication restrictions that must be followed in order to ensure accurate results. This article will discuss these restrictions as well as any other considerations before testing.
Dietary Restrictions: It is important to follow a low-fiber diet for at least three days prior to the test. Foods such as raw fruits and vegetables, whole grains, nuts, seeds, popcorn and processed foods should be avoided during this time period. Additionally, it is recommended that red meat also be avoided since it can cause false positive results on the test.
Medication Restrictions: Certain medications may interfere with the accuracy of the test so they should not be taken within 48 hours of taking the test. These include aspirin or other nonsteroidal anti-inflammatory drugs (NSAIDs), iron supplements and vitamin C supplements which can all lead to false positive results on the tests. It is important to check with your doctor before stopping any medications prior to taking this type of test.
Risks and Complications of a Fecal Occult Blood Test
The fecal occult blood test is a simple and safe way to detect the presence of hidden blood in the stool. However, there are some risks associated with this test that should be taken into consideration before undergoing it.
Risks of False Positive Results: A false positive result occurs when the test indicates that there is blood present in the stool, even though none exists. This can occur due to certain medications or supplements containing iron or vitamin C, as well as from eating red meat within 48 hours prior to testing.
Risks of False Negative Results: A false negative result occurs when the test fails to detect any hidden blood in the stool even though it is present. This can happen if too little sample was collected for testing or if bleeding has stopped by the time of collection. It may also occur if dietary restrictions were not followed properly prior to testing, such as avoiding red meat for two days before collecting a sample.
Potential Complications from Testing: Although rare, complications may arise during a test due to improper handling or storage of samples after collection. If samples are not stored at an appropriate temperature they may become contaminated and lead to inaccurate results which could cause unnecessary anxiety and further tests being performed unnecessarily. Additionally, incorrect techniques used during collection can lead to contamination resulting in unreliable results as well as discomfort for those undergoing testing.
Overall, while generally considered safe, it is important for those considering taking a guaiac fecal occult blood test to understand all potential risks beforehand in order to make an informed decision about whether or not this type of screening is right for them.
Understanding Your Results from a Fecal Occult Blood Test
Interpreting Positive Results: A positive result from an FOB test indicates that there is blood present in the stool sample. This could be caused by a number of conditions, including ulcerative colitis, Crohn’s disease, colon cancer or polyps. It is important to follow up with your doctor if you receive a positive result so they can determine the cause and provide appropriate treatment.
A negative result from a test means that no traces of blood were found in the stool sample. While this may indicate that there are no serious underlying health issues, it is still important to discuss any symptoms you may have been experiencing with your doctor as other tests may need to be performed in order to rule out any potential problems.
Follow Up After a Fecal Occult Blood Test
When to Seek Medical Attention After Testing: If your test cards results are positive, it is important to seek medical attention as soon as possible. Positive results may indicate the presence of colorectal cancer or other serious conditions that require immediate treatment. Additionally, if you experience any symptoms such as abdominal pain, rectal bleeding, or changes in bowel habits after taking the test, you should contact your doctor right away.

A positive result should always be followed up with further testing to determine the cause of the abnormal result.
What is the most common cause of occult blood in stool?
The most common cause of occult blood in stool is gastrointestinal bleeding, usually caused by ulcers or other conditions such as colorectal cancer. It can also be caused by certain medications and foods that contain high levels of vitamin C. Other causes include inflammatory bowel disease, hemorrhoids, anal fissures, and diverticulitis. Diagnosis typically involves a combination of physical examination, laboratory tests, imaging studies and endoscopy to determine the source of the bleeding.
How is a occult blood test done?
A occult blood test is a medical diagnostic procedure used to detect the presence of hidden or "occult" blood in stool samples. It involves collecting a sample of stool and testing it for traces of hemoglobin, which is an indicator that there may be bleeding somewhere in the digestive tract. The results can help diagnose conditions such as colorectal cancer, ulcers, and other gastrointestinal disorders. This test is typically done at home with special kits available from pharmacies or online stores. A doctor may also order this type of test if they suspect a patient has an underlying condition that could cause internal bleeding.
When is a faecal occult blood test done?
A faecal occult blood test (FOBT) is a medical screening test used to detect hidden blood in the stool. It can be used to help diagnose gastrointestinal conditions such as colorectal cancer, polyps, and ulcers. The FOBT is typically done by collecting three separate samples of stool over a two-day period and sending them off for laboratory analysis. Results are usually available within one week after collection.
