How long after contact does it take for poison ivy rash to appear?

I have never in 54 yrs had poison ivy. Two weeks ago I was in contact with it and am now just getting symptoms, is that possible?|||As a rule, the rash of poison ivy will show up anywhere from two to ten days after exposure, depending upon both how allergic you are to the plant oil, and how much oil got onto your skin. If you got only a small amount of oil on you, and you are not highly allergic to it, two weeks would be an outside time limit for the rash to appear.
