It costs less than $250. it's a test where I prick my finger and fill 5 little circles with blood, and send it in to a lab that will test for the 96 allergens. I believe I will be starting an elimination diet after the test, if nothing shows up.
Okay then, its the ELISA test. When you get the results, don't take it as absolute gospel. There are a number of problems with ELISA testing that can produce inaccurate, misleading results. You should do some research on this issue on the internet. What is really telltale in this regard is if you were to have your blood sample sent to several different labs. What you find is that the results from each lab can vary considerably. The other big issue withe ElISA testing is that the lab results often don't correlate well with what you actually experience in real life symptomatically. For instance, the ELISA test results may indicate you have a strong allergy to peanuts. But when you eat peanuts you suffer not ill effects. Or it may indicate that your are not allergic to soy but you know that every time you use soy you get a gut ache, diarrhea or nasal congestion. So with ELISA testing there can be and usually are some false positives and some false negatives.
Having said all that, there is value in ELISA testing. It's a place to start. It gives you things to look for and to challenge or test in your actual day to day eating habits. ELISA testing is more valuable if you can afford to have blood samples drawn and sent more than one lab so you have results from more than one source to compare and contrast.
