Fecal Occult Blood Test

We remind you that independent interpretation of the results is unacceptable, the information provided below is for reference purposes only.

The fecal occult blood test (FOBT) is a screening test used to detect hidden (occult) blood in the stool. It is primarily used to screen for colorectal cancer or other gastrointestinal conditions that may cause bleeding in the digestive tract.

Purpose and Procedure

The FOBT is a non-invasive test that checks for the presence of trace amounts of blood in the stool, which may be an early sign of colorectal cancer or other bowel disorders. The test involves collecting a small sample of stool, which is then tested for the presence of blood using a chemical or immunochemical method.

To perform the test, the patient will collect a stool sample at home using a special kit provided by the healthcare provider. The sample is then returned to the laboratory for analysis.

The FOBT is a valuable screening tool as it can detect small amounts of blood that may not be visible to the naked eye, potentially indicating the presence of precancerous or cancerous growths in the colon or rectum.

The Role of Fecal Occult Blood Test in Diagnosis

The Fecal Occult Blood Test (FOBT) is a screening tool used to detect the presence of occult (hidden) blood in the stool. This test plays a crucial role in the early detection of colorectal cancer, as well as other gastrointestinal disorders that may cause bleeding. By identifying the presence of blood in the stool, the FOBT can help healthcare providers determine the need for further diagnostic tests and interventions.

Indications for Ordering the Fecal Occult Blood Test

The Fecal Occult Blood Test is typically ordered in the following situations:

Colorectal cancer screening: The FOBT is an important screening tool for individuals at average risk of developing colorectal cancer, typically recommended for those aged 50 and older.
Evaluation of gastrointestinal symptoms: The test may be ordered to investigate symptoms such as abdominal pain, rectal bleeding, or changes in bowel habits, which could indicate the presence of conditions like inflammatory bowel disease, ulcers, or polyps.
Follow-up after positive findings: If an initial FOBT is positive, additional testing, such as colonoscopy, may be recommended to identify the source of the bleeding and determine the appropriate treatment plan.
Monitoring of certain conditions: The FOBT may be used to monitor individuals with known gastrointestinal conditions, such as Crohn's disease or ulcerative colitis, to detect potential flare-ups or complications.

The interpretation of the Fecal Occult Blood Test results should be done by a qualified healthcare professional, and any deviations from normal findings may indicate the need for further evaluation and testing.

Preparation for the Fecal Occult Blood Test

Before undergoing a fecal occult blood test, certain preparations are recommended:

Dietary Restrictions: You may need to avoid certain foods and medications that can interfere with the test results, such as red meat, iron supplements, and non-steroidal anti-inflammatory drugs (NSAIDs).
Medication Review: Inform your healthcare provider about any medications you are taking, as some drugs can cause false-positive or false-negative results.
Timing: The test may require collecting multiple stool samples over a period of time, typically two to three consecutive bowel movements.
Handling Instructions: Follow the specific instructions provided by your healthcare provider or the laboratory regarding the proper collection, storage, and transportation of the stool samples.

Only a qualified specialist can provide an accurate diagnosis and appropriate treatment.
