Normal Results

A negative result is normal. It means you have no evidence of gastrointestinal bleeding.

Normal value ranges may vary slightly among different labs. Talk to your provider about your test results.

What Abnormal Results Mean

Abnormal results of the flushable pad mean there is bleeding present somewhere in the digestive tract, which may be caused by:

• Swollen, fragile blood vessels in the colon that may result in blood loss
• Colon cancer
• Colon polyps
• Enlarged veins, called varices, in the walls of the esophagus (the tube that connects your throat to your stomach) that bleed
• When the lining of the stomach or the esophagus becomes inflamed or swollen
• Infections in the stomach and intestines
• Hemorrhoids
• Crohn disease or ulcerative colitis
• Ulcer in the stomach or first part of the intestines

Other causes of a positive test, which do not indicate a problem in the gastrointestinal tract, include:

• Coughing up and then swallowing blood
• Nose bleed

Abnormal test results require follow-up with your doctor.
