Could i get a colon guard test?

These are likely available through a local doc. This is a public information site where volunteer docs answer questions about health conditions based on info you post. It does not provide scripts/notes/order tests/review x-rays or provide other direct patient care.

If so recommended by your doc, circumstances will be otherwise needed for a recommendation. Talk to your primary care doc or gastroenterologist.

You could, but it would more useful to have a screening colonoscopy.
