BTD Forums  /  Live Right 4 Your Type  /  Will secretor status affect cancer blood tests?*
Posted by: skoriginal, Tuesday, July 21, 2009, 5:43pm
Hi everyone!  I keep coming back to the BTD... Just need to STICK with it!

Does anyone know if being a non-secretor would affect blood tests that screen for cancer, like CA125 for instance?  Also, does it impact allergy testing?

This is something I've been wondering about and thought I'd ask. :)

Thanks for your input!

It affects CA19-9, CA 27-29, Sialyl Lewis X and DUPAN.

These tumor markers will be missing or artificially lower in non-secretors.

Hi Skoriginal,
  Do yourself a favor...don't leave anymore. Take it from someone who futzed around since 1998 leaving and coming back and finally realizing after trying every diet from Atkins to Weight Watchers, that I only felt really good on the A diet and then even better on an individualized diet from Dr. D'Adamo.  :)

Thanks so much for your replies!

Dr. D'Adamo, I am honored that you responded to the question. :)  Thank you again so much... The reply was very helpful!

Mayflowers, you are SO right.  I'm convinced and read through LR4YT last night again.  It's the plan I feel best on and I know it's right for me (and good for everyone who follows it).  I need to keep coming here and find a few buddies to keep me on track.

Very best wishes... Thank you again,
Stefani

That is very interesting. I had blood tests for CEA, CA125, CA15.3 and CA19.9AxSym and they were all negative. I thought that this was great, but from reading your post, Dr. D., it seems that at least CA19.9 would be low anyway due to me being non-secretor.
Are there any other tests non-secretors could do that would be more meaningful?

This is very interesting and worthy of a five star rating for the thread.  I wonder if doctors, presumably knowing about the above-stated influences of secretor status on certain tests, always test for secretor status when doing those other tests.  One would hope so.

Note:  I'm going to place a link to this thread as a sticky in the nonnie forum, as it could help get this info to more people.  However, the thread itself seems to be in the correct forum, since LR4YT is the place to discuss secretor status information and issues (while the nonnie clubhouse is more a place for peer support for nonnies).

we are trying to get the lewis test implemented here in Switzerland, but often docs tells us that this method isn't valid or even not needed or too old  :-/......

Good info to run circles around the docs at the hospital. ;).
Love to see their faces when I come out with something that sounds smart. :)

The question I have is: Are there other tests we can do if the cancer tests are not valid for nonsecretors? Or do we just have to accept that there are no tests for us?

no, simply educate your Dr on that very fact, hand him written scientific info, make him aware so he interprets your exams accordingly.
