Testing Question

[bramblef]

All the RAST testing came back normal (within normal ranges). I have several reactions that put in in the ER due to Shellfish. I was tested for lobster, clams, shrimp and tuna. 

Skin testing is now scheduled for Friday.

Does this ever happen? Can you get a negative blood test and positive skin test?

Absolutely.  It's even possible for both to be negative, though far less probable.

This is why I stated that with your history, any allergist SHOULD offer you an in-office food challenge if your skin test is negative.

Back again.
Skin test was inconclusive. 

Allergist put me on daily certizine for allergy management and wants to see me in September.

A little frustrated as all my anapahalactic reactions had shellfish as the trigger, yet blood test was negative and skin test was in conclusive.
