If you really wanna find out if you're allergic to poison oak, roll around in those bushes at the beginning of Dog Mountain Trail. Then grab those "leaves of 3" and use these to wipe off in that outhouse. After 3 days with no rash... you're one of the lucky ones.
I've actually become more tolerant of poison oak in the last 10 years, maybe it's just because I've learned to rinse it off soon after exposure.
