Blood IgE or Skin Prick test?

[Guest guest]

I just called our Ped's office to see if she can order a blood IgE for

inhalant allergies for my 4yo, and she said that I need to take him to an

allergist to do a SPT because blood test would be inaccurate at his age. I

thought from what I read that blood IgE is far more accurate? And it's going

to be nearly impossible to keep him still for 15 min for the SPT.

Any input is appreciated!
