We did a blood test when my son was a around 15 months to check for allergies, as a possible trigger to his eczema.  It showed that he wasn't allergic to anything.  

 

His eczema is still a problem at age 2 1/2 and I'm wondering if we should re-do the tests, if there's a certain test that I should make sure we do (what is it called?), and if I should see a special doctor (like an allergy specialist?)

 

 

Thanks!

Blood tests are not 100% reliable and will only pick up true IGE allergies if done at an allergist's office. It won't pick up sensitivities to food which can often be an eczema trigger.

You could ask your naturopath to do an IGG blood test but those tend to yield a number of false positives/negatives as well.

Have you considered an elimination diet to see if you can pinpoint the source?

In the meantime, keep the skin well moisturized-- plain EVOO works great.

Good luck!

80% + of the time eczema is not food related.  It can often be environmental.  IgE tessting as stated will only pick up a true (possibly anaphylactic) allergy but IgG testing is really kind of not informative as the testing doesn't really hold a lot of scientific basis behind it.  

 

I would limit bath/water time (we do twice a week, no soap) and a good moisturizer (we use vanicream).  We did at one point do bleach baths too when desperate and they helped a ton. When done right, they are diluted to the point of being like a pool with chlorine.  We did a clear water rinse at the end as well.

Are there any tests for sensitivities?

Do regular doctors not do the IGG test?

 

 

We suspect a gluten sensitivity for my son, and we've kept him off of it for the last 6 months or so,.... but when he ends up having a bite of something (like bread) we don't see any reaction. 

 

We think my husband has a gluten sensitivity and he says that he thinks the sensitivity seems to be cumulative.  So, if he has a little here and there, it's okay....but if he has it often, for several days in a row....he's not feeling very well.

 

Does that sound like how a sensitivity behaves? (vs. an allergy)

 

 

Since he still had new outbreaks of eczema while off gluten for a while, I'm thinking there's something else.  He almost never eats dairy, eggs, or anything with soy....but he does eat corn...in the form of chips, tortillas (tacos), and tamales.  Mexican carne asada tacos and tamales are his all time favorite food.

 

I can try elimination.  I was just hoping there was a good test, so that I feel like I have the facts...instead of just feeling like I'm guessing.

I think you'd still be guessing, even if you had the tests. We have done two IGG tests with my DD. Eliminating all the IGG foods did nothing for her chronic looser stools, until we started an elimination diet.

Correct that most "regular" (eg, allopathic) doctors do not do IGG testing. They don't consider it credible. Many naturopaths do it but jury is out in how to interpret the results. I don't think there is any blood or skin test which is 100% reliable, unfortunately.
