What is the best fit test for colon cancer?
Colonoscopy

Can a fit stool test detect cancer?
The fecal immunochemical test (FIT) looks for hidden blood in your stool that could be coming from colon cancer. Studies show that FITs can be nearly 80% accurate in detecting colorectal cancer. The test should be done annually.
Is a fit kit as good as a colonoscopy?
Although FIT is less effective for neoplastic detection than colonoscopy or sigmoidoscopy, evidence suggests that it may be better accepted,20,21 and higher acceptance may counteract its lower detection capacity. It has been suggested that FIT may be more effective and less costly than other screening strategies.
How often do you do fit testing for colon cancer?
The FIT-DNA test (also referred to as the stool DNA test) combines the FIT with a test that detects altered DNA in the stool. For this test, you collect an entire bowel movement and send it to a lab, where it is checked for altered DNA and for the presence of blood. It is done once every three years.
How accurate is fit test for colon cancer?
On average, the review found that FITs catch about 79 percent of colon cancers, and their specificity consistently tops 90 percent. That means the tests accurately give a negative result to more than 90 percent of people who do not have colon cancer.
Can you have colon cancer with a negative fit test?
Normal or Negative Results A normal or negative FIT result means that there was no blood found in your stool at the time of the test. If a stool test is negative, it does not always mean colorectal cancer or colon polyps are not present. That is because these tests can miss polyps and some cancers.
What happens if my fit test is positive?
Abnormal or Positive Results An abnormal or positive FIT result means that there was blood in your stool at the time of the test. A colon polyp, a pre-cancerous polyp, or cancer can cause a positive stool test. With a positive test, there is a small chance that you have early-stage colorectal cancer.
Is Fit test better than cologuard?
How Accurate is the Cologuard test? Cologuard can detect 92% of cancers but only 42% of large precancerous polyps. Cologuard is better at detecting cancer than FIT (92% vs 74% for FIT), but the false positive rate is higher. Cologuard has a 13% false-positive rate, and that rate increases as people age.
How accurate is fit kit?
Results showed that a FIT test is effective at ruling out colorectal cancer with 99.8% accuracy whilst at the same reducing the need for invasive investigations and a visit to the hospital in approximately 60% of patients with a negative FIT result.
Can polyps cause a positive fit test?
risk factors you may have for colorectal cancer, your doctor may recommend various time intervals between tests. An abnormal or positive FIT result means that there was blood in your stool at the time of the test. A colon polyp, a pre-cancerous polyp, or cancer can cause a positive stool test.
What should I do if my fit test is positive?
People with a positive FIT test result are advised to have a colonoscopy to investigate the cause of the bleeding because a FIT test alone cannot diagnose cancer.
