It is certainly one of the steps involved in the screening and diagnosis. Antibodies to various proteins including Baker's or Brewer's yeast (saccharomyces cerevisiae) and bacteria like Escherichia. coli (E. coli) are present in the blood of many people with Crohn's disease but show up rarely in non Crohns people.

Did Dennis Kucinich suffer from Crohn's disease and cure it by eating vegan?

No, sorry. No one is cured no matter what you read. Crohns has no cure. Crohns patients have remissions and these can last for years but once you are diagnosed with Crohns disease you have it forever. A simple blood test can be done on even a patient in full remission and will always show up positive for Crohns. If it were that simple all of us who suffer from Crohns would gladly eat Vegan, it would be a great alternative to not eating at all during a flare up.
