There seems to be negative opinion on this test aka LEF FoodSafe Test.   Can anyone point out double-blind studies and or large number controlled anecdote that indicates this test is useful in fine tuning diet for health?

Yes what Dan is asking could be very interesting. The test measure IgG. I had several times IgG, IgA and IgM measure together. Taken together the test can give overall information on immune system functioning, reaction to infection and autoimmune disease.

With food intolerance increasing many are offering similar tests. From 245 to 505 Euros, this company offers test from 90 to 270 nutrients (sorry in French):

Question to LEF: can I take this test (LCM73001) from remote (Switzerland)?

A brief google search isn't showing me that there are labs in Europe that run the Food Safe Allergy Test, but that doesn't mena there aren't any.

That company offers a similar test to the one offered by LEF. LEF's test looks slightly cheaper though which is good service to Members. I think I am going to take the test from LEF.

Sorry .. I forgot ... is that LEF test purchasable also from outside US. I will travel in US next months so maybe I can arrange a blood draw once there but do not prefer.

DDye I know this is not you main task here but maybe you might have a reply.

Life Extension's Member Services department provided the following reply:

They can place an order for the blood test but would needto provided us with details on the state they will visit to have the test done.  They would provide that information on the patient information they will set up during the checkout process online.  If they call, a representative will be able to assist them.

Thank you DDye for having  forwarded the request. I guess by "state" they mean the county I live in (Switzerland). I will check with them. I will travel in US next month (not FL, but CO) for about one week: I wonder if I could do something there to take this test, e.g finding a LabCorp station? I do not have practice with it.

PS
I see even for you the long standing problem of spelling when copying/pasting from a different text editor is not solved yet and words get glued together.

They mean the state in which you will be having the test done.  To find a lab, see https://www.labcorp.com/wps/portal/insurer/findalab

Yes, one wonders about the pasting situation--perhaps it was intended to discourage pasting copyrighted material.

A critic view on the IgG-4 test:

https://www.aaaai.org/Aaaai/media/MediaLibrary/PDF%20Documents/Practice%20and%20Parameters/EACCI-IgG4-2010.pdf

I think I will pass it anyway as valuable to see general trends (vs. solid clinical relevance) and wonder if you researched more extensively.
