blood tests for allergies?

My ENT is sending me to an allergist tomorrow. I had some allergy blood testing in 2005 (RAST - I think) and it only showed a cat allergy.

I actually have LOTS of allergies to both food and inhaled things, but my last skin test (over 10 years ago) caused me to have difficulty breathing because I had a positive reaction to so many things.

I'm wondering if anyone knows if there are any more accurate or better blood tests for allergies than the RAST test? I really don't want the skin testing again if I can avoid it.

Also, I've been off of my zyrtec for a few days now (just in case I absolutley need skin testing) and my whole body is itchy, no hives, just really bad itching all over.

Re: blood tests for allergies?

The blood test just isn't that accurate for environmental allergies. The skin test is the gold standard at this point.
