In Reply to: RAST test for allergies?? posted by Kristie on February 24, 2000 at 09:08:26:
: My daughter's doctor is now suggesting using something called the RAST test, which involves a blood sample, for allergies. Has anyone had this done? Was it more effective than a skin test?
My son broke out in hives at 9 months after having scrambled eggs. We did a skin test and it was determined that he was definitely allergic. He is now 2 years old and our Dr. recommeded that we do the RAST test, because he feels it is the most accurate test out there. The test runs on a scale..I'm not sure what the actual numbers are, but my Dr. said I should view it on a scale of 1 to 6, with 6 being most allergic. My son scored a 5 for egg whites, and a 4 for egg yolks. What is interesting though, is that the Dr. also requested that he be tested for allergy to cow milk. Although he has consumed cows milk for over a year with no problems whatsoever, the RAST test gave him a score of 5 for milk. This leads me to somewhat question the validity of these results. But I'm not about to challenge them. I was told that my son should be tested in another year to see if there are any changes. Until then, I will definitely consider him to be severely allergic to eggs and will have to carry the Epipen everywhere I go.
