Things you need to know about the Fecal Occult Blood Test

FOBT for Colorectal Cancer


A Fecal Occult Blood Test (FOBT) is an at-home test that detects hidden blood in your stool. A FOBT is used to check for colon cancer. Small amounts of blood normally appear in the stool, hence tests for occult blood are designed to detect larger quantities of blood in the stool.

Taking the Fecal Occult Blood Test

The FOBT requires 3 small stool samples. The samples are collected with the end of an applicator. The stool samples have to be taken one day apart, since colon cancers do not bleed consistently and may bleed from time to time.

The fecal occult blood test kits can be performed at home. The stool samples are collected in a clean container. It is evaluated by detecting color changes on a test card. You can also send the sample in a special container and envelope to the doctor's office for analysis.

Frequency of the Fecal Occult Blood Test

Doing the fecal occult blood test is recommended yearly for people starting at age 50. This will allow for the early detection and prevention of colorectal cancer.

Results of the Fecal Occult Blood Test

A positive FOBT result means that blood was found in your stool. Your doctor will analyze the source of the bleeding by doing a colonoscopy or an examination to determine if the bleeding is coming from the stomach or small intestine.

A negative test result means that no blood was found in the stool sample during the testing period. However, regular screening for colorectal cancer is recommended.
