I had a skin prick done by an allergist on May 04. After the test and received my test results I decided to get a second opinion so I made an appt. (June 10) with a different allergist for another skin prick test.

The results of both of these test do not even match at all, they contradict each other.

 

I also has a blood serum test done in July 2007 for allergies, and the test results for that test doesn't even match with either of the 2 skin prick tests I've had done. This is so confusing!!!!!!!!!!!!!!

I do not even know which test is accurate, or which one to believe to go by!

 

Has anyone had more then one skin prick test done and the results contradict each other results?

Thanks,

This is because the test serums are not standardized. Different doctors use different dilutions, which can have an impact on results. Also, reactivity varies from day to day (my Husband notices this with his food allergies since he has so many food allergies and he has to eat something - some days he gets no symptoms, other days he has mild swelling in his mouth & esophagus from the same food that causes no problems other days).

The best way to figure this all out is to do an elimination diet - avoid all foods that have ever turned up positive on any test for a period of 2-3 weeks. Then add back one food at a time. Watch for symptoms disappearing during the avoidance period that return when you challenge the food again, and watch for new symptoms. If you experience a symptom upon re-introduction of a food, avoid it again for 2 weeks and try it again to see if the pattern repeats. This takes a lot of patience, but is really the only way to figure out which foods you really do need to avoid.

Also, an IgG blood test for delayed food allergies may give you more information. Some of my worst offender (most serious reactions) foods show up on IgG tests and not on IgE tests or skin prick tests.

I hope this helps,

Hi Razzle,

Thank you for your reply.

If I avoid all the foods these 3 allergy food test show that I'm allergic to there will be no foods left for me to eat.

I guess I could eat lettuce since that's not listed on any of the test.

According to all 3 test it shows I'm allergic to all meats & seafood(chicken, beef, pork & fish). Surely this isn't accurate!

These test are not free! They cost alot of money. Even tho my ins. covers most the cost I still have to pay a certain percentage (co-pay) of the bill. I would think that one could trust these allergy test, but this is not the case as far as I'm concern.

 All 3 test are not accuate in my eyes being they all contradict each other.

I have the same symptoms as you described about your husband.

My throat feels as if it is closing up (swelling) and I have a hard time breathing everytime I eat anything at all. When I wake up everyday I do not have any of these symptoms til I eat something. I eat something and the symptoms are right back.

I'm so tired of this and I'd hope that by having this food allergy testing done and avoiding foods that I'm allergic too would help. But like I said, I'm allergic to everything according to these 3 food allergy test.

Sorry I'm rambling on and may not be making alot of since here, but I'm upset and bent out of shape about the whole ordeal. I weak and losing weight beccause I'm scared to eat anything!

Thanks for listening,

Sabrina

Hi Sabrina,

Have you tried drinks like Ensure or Boost (or even Slim Fast) to see if you can handle them without getting the reactions? This might give you some nutrition and calories to help stop the weight loss and enable you to experiment with your diet a little.

Also, my husband (who also is allergic to all meats/poultry/fish/seafood) has found that he can eat Hormel canned chunk ham without getting symptoms because the ham has been sitting in salt in the can for a while and apparently the salt breaks down the proteins enough so that they don't trigger his allergy to pork. So this might give you some ideas for things to try.

Does all food do this to you, or can you eat simple things like plain rice or applesauce without symptoms?

Take care,

Hi Razzle,

 I'm not to sure what all is in the drinks you suggested but I will take a look at the ingredients on the cans of them.

2 of my test show me allergic to cocoa beans, so if there's any choc. in them I would have to rule those drinks out, or try them and see what happens.

2 Test show me allergic to dairy products and 1 test doesn't, which was this last skin prick test I had done on June 10th.

Only one test shows me allergic to chicken, the other 2 do not show me allergic to chicken. I've been eating some chicken with no seasoning on it at all and with a side veggie (broc. or green beans).

I think what I will do is try just chicken with a side bowl of lettuce for a few days and see I get any relief from symptoms. I'm also going to make an appt. with an Ear, Nose & Throat doctor to rule out any kind of tumor in my throat. Heck I gotta do something here or I'll blow away within a  few months I lose so much weight.

I will google the drinks and see if i can come across the ingredients on the drink you suggested. I know this is a one day at a time thing and I think God my symptoms haven't ended me up in the hospital because my throat has closed completely. So I guess that's a good thing while I try and figure out just what all I can eat and what I can not eat.

Thanks for your advise and I sure will look up those drinks, I'm know they will help a lot if I can drink them.

Sabrina
