FOBT - Bowel Cancer Screening

A non-invasive stool-based test that detects hidden (occult) blood in faeces — an early warning sign of bowel cancer and pre-cancerous polyps. Bowel cancer is the second most common cancer in Australia and the second leading cause of cancer death, yet it is over 90% treatable when detected early. The Australian government recommends screening every 2 years from age 50, but this private option allows earlier or more frequent screening without a GP referral.

Bowel cancer (colorectal cancer) is the second most common cause of cancer death in Australia, yet it is one of the most preventable and treatable cancers when detected early. The five-year survival rate exceeds 90% when caught at stage one but drops below 15% at stage four. The faecal occult blood test (FOBT) detects hidden blood in stool — blood that is invisible to the naked eye but indicates bleeding somewhere in the gastrointestinal tract. Bowel cancer and pre-cancerous polyps often bleed intermittently into the bowel. The FOBT uses immunochemical methods (FIT — faecal immunochemical test) to detect human haemoglobin in stool with high specificity — it does not react to dietary blood from meat, reducing false positives compared to older guaiac-based tests. A positive result does not diagnose cancer but identifies people who need further investigation, typically a colonoscopy. The Australian National Bowel Cancer Screening Program sends free FOBT kits to eligible Australians aged 50-74 every two years. However, bowel cancer incidence is rising in younger adults, and many practitioners now recommend earlier and more frequent screening — particularly for those with a family history of bowel cancer, polyps, or inflammatory bowel disease. ClearLabs offers this test without a GP referral and without waiting for the government screening schedule. The test uses a home collection kit — a small stool sample is collected according to provided instructions. No dietary restrictions are required with the immunochemical method. ClearLabs delivers results within 2-3 business days through the confidential digital dashboard. For adults over 45, or those with any family history of bowel cancer, regular FOBT screening is one of the highest-value preventive health investments available.
