Is it really neccessary for a vegan to be tested for high cholesterol?

I’ve been recommended for a high cholesterol test, and really just want to know why. I don’t really care, but it just seems odd- y’know, as a vegan I consume no animal products, and I don’t think that I’ve really ever knowingly consumed a tropical oil, or at least I haven’t often. But they recommended me for the test because of heredity, and I was wondering why they thought that high cholesterol would still be an issue. Can anyone explain?
