For a FIT-DNA test, what is required from the member?

The FIT-DNA test, also known as multitarget stool DNA testing, is designed to screen for colorectal cancer and precursors to the disease. This test analyzes DNA and heme (blood) from stool samples to detect abnormalities that may indicate cancer or polyps.

The requirement of an entire stool specimen is crucial because the test needs a sufficient amount of material to accurately detect the genetic markers or traces of blood that can signal potential health issues. Using a complete stool sample ensures that the test can cover a range of possible signs of colorectal cancer, providing a more comprehensive evaluation than a smaller or partial sample would allow.

Other specimen types, such as urine samples, blood tests, or saliva samples, do not provide the specific information needed for colorectal screening and do not contain the necessary genetic material or indicators related to the intestinal tract. Therefore, these options are not suitable for the FIT-DNA test, affirming that a full stool specimen is essential for accurate testing and diagnosis.
