Fecal Occult Blood Test: What You Need to Know

A positive result in a fecal occult blood test can occur for various reasons. One common cause is the consumption of red meat or animal blood, such as blood pudding or blood tofu. However, the color of the stool plays a key role in interpretation. If the stool remains yellow and the individual has consumed a significant amount of meat, especially blood-based foods, a temporary positive result may occur. This is typically not a cause for immediate concern.

Understanding a Positive Fecal Occult Blood Test

When a fecal occult blood test returns positive, it means that there is blood present in the stool that is not visible to the naked eye. While diet can influence the result, persistent positivity—especially with three plus signs or more—should not be ignored. This may suggest the presence of bleeding in the upper gastrointestinal tract, such as from an ulcer, gastritis, or even more serious conditions like colorectal cancer.

Self-Assessment and Common Causes

Before seeking medical help, individuals can perform a basic self-assessment. Conditions such as hemorrhoids, anal fissures, or rectal inflammation may also lead to positive results. Mild gastrointestinal discomfort or occasional bleeding might be related to dietary habits or benign issues. However, if symptoms persist or worsen, medical evaluation becomes essential.

When to See a Doctor

If the stool appears consistently black—known as melena—or resembles blood pudding, this could indicate internal bleeding. In such cases, it is crucial to visit a healthcare provider for a comprehensive examination. Diagnostic procedures like colonoscopy or endoscopy may be recommended to identify the source of bleeding and determine the appropriate treatment plan.

Early diagnosis and treatment are vital in addressing any underlying gastrointestinal issues. A healthcare professional can help interpret the results accurately and guide patients toward effective management strategies, including medication or lifestyle changes.
