Guest maybe I have celiac

Ok, after months of suspecting gluten and casein are causing my depression,anxiety and so on, I will have blood drawn tomorrow. I will be tested for wheat, milk, gluten, among several other foods.

Three questions:

1. What do you think of the RAST? Reliability and accuracy.

2. Did you have any surprises when the test results came back?

3. Anyone have similar circumstances as me in terms of neurological conditions? Again my symptoms are mostly in the brain.

Oh and I have lost 15 pounds the past two weeks, I think exercise and avoiding gluten and milk - Any comments about this???

In general, the skin prick tests are better and more accurate than RAST. RAST is supposedly not as sensitive as skin tests for IgE allergies. I believe this to be true with my allergy testing experiences. I have had better success with allergy shots for pollen allergies based on skin tests than I have from the RAST test. Many pollens that showed up in skin testing did not show on my RAST test. Also, my wheat allergy was very iffy on RAST. A negative result was <0.05, mine was 0.08, which most allergists would say was a borderline negative result. But on the skin test, there was no mistaking it, it was positive. The blood tests can also have a false positive, and show borderline reactions to allergies that you have actually outgrown, much in the same way as you will test positive for antibodies for diseases in which you have been vacinated against. The skin test, on the other hand, is very indicative of what you are allergic to at the moment you are tested. Though they aren't foolproof. Allergy shots can affect the results of skin tests.

All of this said, if you test positive to a RAST and it is very high, you can be confident that you are indeed allergic to that food. The trouble comes when people start interpreting borderline results as positives.

The newest test for food allergies is the ELISA panel, which measures IgG, not IgE. Many experts believe the ELISA is a better choice to test for food allergies, but it hasn't been embraced by everyone yet.

I'm sure you know, but I want to clarify, that the RAST or any other allergy test is not the same as a celiac panel.

    In addition to celiac & rheumatoid arthritis, I also have Reynaud's syndrome. Mine occurs mostly with my fingers. Sometimes my toes get affected if it's really cold.  The grocery store is the worst for me. I hardly ever go in the grocery store without the Reynaud's hitting my fingers. I've tried wearing winter gloves but they don't seem to make one shred of difference. I've also tried using the Hot Hands hand warmer packets in each pocket & putting my hands in my warm pocket with th
    Thank you everyone I went for a second opinion just to re do the blood work hoping I can find out a answer. Last week I had the upper stomach pain again but no celery juice since November so I’m at a loss 😭 but all of my celiac panel including the genetics were negative just that ema which the second doctor said 1:20 is on the low side not sure if that’s true 
It is not a rash, but hives and swelling.  Some doctors think it is a separate autoimmune disorder or that it piggybacks on to others.  It is more commonly associated with autoimmune thyroiditis.   My last bout lasted for six months.  They appeared (from my head to my soles of my feet) every afternoon around 4:00 pm and resolved by morning.  Oddly, they start with abdominal pain.  That is my first clue and next an itchy head.  I was on a cocktail of antihistamines and attempted a low histam
