Would a CT colonography be a good test to do before the full Colonoscopy even after a positive Cologuard test?
I have a lot of anxiety about a Colonoscopy and I need more proof before doing a fully invasive Colonoscopy.

No. I don’t recommend it. Colonoscopy is the best test to evaluate positive Cologuard.
A positive Cologuard is very sensitive so I would say it’s best to proceed with the Colonoscopy to remove any polyps or to determine if there is a mass.
A CT colonography must not be done if Cologuard is positive, you need a properly-prepped Colonoscopy. A CT colonography may rarely be necessary after a Colonoscopy, especially in a high risk case where the full colon could not be examined for some technical reason. A CT colonography must not be done before a Colonoscopy as polyps are common (30-50% of cases) and it will require you to undergo another prep and Colonoscopy at great expense and no benefit.
