BTD Forums  /  Nonnie Clubhouse  /  Lewis Antigen panel issues?
Posted by: Beachgirl, Monday, April 16, 2012, 6:05am
I just had all my blood work done for my yearly physical with my primary MD.  I requested the Lewis Antigen Panel, which was difficult as neither the lab, nor my MD were familiar with it.  After I made what seemed like several hundred phone calls between the lab & my MD, I finally got a code for the lab & the reluctant agreement from my MD to request the test.  On Friday, I had my blood drawn & was informed by the lab that they have no idea what the test is, who it needs to be shipped to for testing, that the code they (the lab) gave me is wrong & that it may be a month or more before I even have results.  Grrr!  This is the one test I was most anxious to get the results on and now I'm not even confident that they'll sort things out enough to send my sample off.  Has anyone else had this issue?  I don't really have the $$ as of yet to get the saliva secretor test, so I was excited that my MD requested it & that it would be covered by my ins.  I'm hoping to have an answer at some point...sooner, preferably than later, but we'll have to wait & see.  If it all goes bust, I'll just have to wait until I have the funds for a saliva test.  Darn!

Yes people often have problems getting Lewis testing done in a lab covered by insurance.

Side issue:

I notice you are using SWAMI. Have you ran SWAMI with different Lewis values to see what changes it would make to your diet?  For some people it does not make a major difference in SWAMI.

I ran into the same problems, especially ignorant MD's.  I gave up. I already knew I was a non through saliva testing, and possibly being LDN doesn't change my SWAMI much anyway.

Your best bet is to have it done at a blood donor center or at a reference lab that also has a blood bank.

or at a large hospital, with blood bank and lab included.....at least down here, that is how it is working out for all my clients.....through blood draw

My ob/gyn ordered the test for me.  He was familiar with it, but he didn't seem to have a grasp of what the ab actually referred to.  I think he confused it with ABO.  Anyway, all I wanted was the results.  My insurance didn't cover it either, I had to pay the lab bill.  I think the test is often done for women trying to get pregnant (?), maybe your gyn is the one to ask for that test.  At any rate, I hope you get it resolved.  I ordered it because I wasn't sure that I didn't mess up doing my saliva secretor test.  But I didn't.  I am indeed a nonnie.

Pregnant women will sometimes have anti Lewis antibodies in their serum after they have delivered a baby.

These antibodies are clinically insignificant unless they are of the IgG subclass.

Aha, thanks for the clarification!  :)

Thanks for the info, everyone.  I did have it done with my normal blood draw for my yearly physical stuff, but I still have no idea whether or not the lab has figured out what to do with it.  Lola & Captain Janeway, with blood draw, do you mean normal blood work with vials (which I had done) or an actual donation of blood?  I don't weigh enough to donate, so that's not an option.

C_Sharp, I have run my SWAMI both ways & have been eating as a nonnie with good results...I just want the clarification.  It'd be nice to know for sure.  If I can't seem to get an answer, then I will have to do the saliva test in a month or so, I was just hoping to sort it all out at once.   :-/

O in V, thanks for the info...maybe I'll place a call to my OB/Gyn & see if there's anything they can do.  :)

Good luck, Beachgirl!
I will be trying to do this soon with my GP...so if he doesn't cooperate I will ask my GYN when I see her this summer. 8)

A blood bank that is part of a reference lab or a hospital lab blood bank will most definitely know what a Lewis antigen phenotype is. Whoever handles writing out orders for blood work would need to make sure the test is sent out to a blood bank that can test for Lewis blood type.
