Almost: Skin test is more sensitive though, results appear within 20-30 minutes, needs to be performed by experienced nurse/doctor, can be tailored to add specific allergens according to patient's environment/exposure, in addition to standard screening panel. Blood test , RAST, is resorted to if skin test cannot be performed for a reason or another.

Is there a simple blood test to see if I am suffering from allergies? One that i could do before skin testing to see if that is even the problem.
