I had a CAT scan done on Tuesday morning. Drank two bottles of the banana contrast and a half a cup at the place. I received the blue dye in a IV. How long does it take to leave the body?

I would think it would be out of your body within a 24/48 hours  now if your allowed to drink water they say drink lots of liquids after these test I know that's what they told me about the MRI I had done.
