Septin9 Blood Test for Colorectal Cancer
The Septin9 blood test by Dynacare Next offers an easy and accurate method to help screen for colorectal cancer. The Septin9 test detects the presence of methylated Septin9 DNA in blood, which has been strongly correlated with an increased risk of colorectal cancer. Septin9 has been shown to have a sensitivity of 70% and specificity of 90% for colorectal cancer. The test is very convenient, since it is performed on a blood sample, and does not require collecting or handling stool samples. It also has no dietary or medicinal restrictions.
Fecal Immunochemical Test (FIT)
The fecal immunochemical test (FIT) is a non-invasive test that checks for hidden (occult) blood in the stool. Polyps or tumours in the colon have blood vessels on their surface that can release a small amount of blood into the stool. The FIT test uses advanced immunochemical technology to determine if there is gastrointestinal bleeding. The FIT has a sensitivity of 100% and a specificity of 99% for blood in the stools, which are much higher than the traditional fecal occult blood test (FOBT). Unlike the traditional FOBT, the FIT has no dietary or medicinal restrictions. In addition, just one stool sample is required.
