Anyone here ever have the secretor test done more than once?  I'm thinking of having it done again.
I know of one member awhile ago who said they had two different results...


Why you say?  I keep craving nonnie food. That's why.

I am presuming you are thinking of doing the saliva test.

You indicate you are A1. I guess that you had a blood serotype panel done to determine the A1.  Did the serotype panel indicate your Lewis blood group?

Have you also done the saliva test once to determine your secretor status?





My thoughts are if you determined your secretor status one way, you could try determining it the other way.

If you did not have the full serotype panel done, doing it could also detemine your MN blood group (and also if you are a Lewis double negative).

If you already determined it both ways, I am not sure I would want to spend money on another test.

I never thought of doing it again, why would you? Do you feel it is off?

Have you tried the unibars?

Saliva tests can be inaccurate?  How often is that?  Oy.

Not often.

The saliva test is the most accurate way to determine secretor status.

http://www.dadamo.com/errata/smartfaq.cgi?cat=1075205564#1075206948




I do not know of instances of it happening with secretor test, but any lab test has the potential for being wrong. Some possible reasons to get inaccurate results on a lab test:

This can be as simple as you switch the sample and report the result from someone else sample to another person.

The reagents used in the test could be old or for some other reason no longer react properly.

Sample is not prepared correctly in the lab.

Sample can be collected incorrectly so something other than normal saliva is collected.

...




Again. We are not experiencing these problems. It is just conceivable that one could get an inaccurate result on any lab test one has done.

Genova Diagnostics is used to process the saliva samples for NAP. This company has proven to be very reliable over the years.

I don't know what my sub group is. There's no information on my blood on my swami other than A1. I had the saliva test before I went to the clinic. Natalie had a lot of trouble finding a vein as most people do who draw my blood so she did a finger stick. I don't even know if she got enough blood to test. I told her I had the secretor test done and she took my word for it.  I don't think she had enough blood to perform all these tests on it. Maybe she got a thimbal full if that. So, I want to see if the test is accurate that I had.

Reactive veins too.  Some people's sympathetic nervous system sort of acts up and the veins "tense" and constrict when blood is being drawn.  Can be a real bu**er to deal with if you must have an IV or blood tests.

I have those kind of veins.  One thing that has helped me is to drink a LOT of fluids for 3 or 4 hours prior to the test to get very hydrated.  Last time I had a blood draw, it was effortless!

Eeek who was that?? I wondered if that was a possibility - esp when they took so long & lost my sample twice     I consoled myself with the thought that if they couldn't find a blood type from my "secretion" then it must be right Anyway I am for sure a nonnie imo (& a gatherer with strong explorer tendencies)
Good luck with whatever you decide to do...

Not sure what Isa said but does it have anything to do with buying a magazine and then 2 weeks later buying the same issue thinking I never saw it yet?  I hate when I do that.    

That's a good idea Victoria I'll have to remember to drink more next time. Interesting Souful, I could have tense veins..

All I remember was I believe the member that had two different results back to back was a male. He was annoyed and wanted to know what to do about it. Someone told him to call the company.

I did a saliva test kit and came back non - secretor
I just had blood done for a visit to the CT clinic and that blood work came back secretor.

I'm assuming the blood work is more dependable?

I had the saliva test done twice. (Both times with NAP.) One time the result was secretor and the other time it was non-secretor. I seem to remember a discussion on the old board about whether a sample could become 'stale' when send half across the world in summer.

how did they determine that?

only through a Lewis test can that be tested

give us your lab results from the Lewis test

important are whether a and b are either positive or negative.

how did yours turn out?

I have also thought about the possibility that the test will show wrong results when sending a saliva sample from Europe since it takes about a week for mail from Sweden for instance, to reach the U.S. but since I do not know exactly how sensitive a saliva sample for testing secretor status is and how the test is performed I can only speculate.

I haven't done any saliva test yet because of that. If I will do it would only be if I for some reason travel to the U.S. I have done a Lewis blood test but since I was Lewis negative I cannot tell secretor status from that so that is of course why a saliva test would have been better but it is probably the best to test both blood and saliva. I am probably a secretor anyway since it seems like most LDN's are secretors in the end even if I have learned that I should consider my self a non-secretor when choosing what to eat from BTD and GTD.

I have been trying to find any lab in Sweden, Scandinavia and Europe that can perform a secretor test from saliva but haven't found any lab yet. I really didn't expect that it would be impossible to find a lab in Sweden (or Europe) that could perform the test, no one seems to know what I am talking about, only the blood centrals but they only test Lewis from blood.

I have seen that there is a lab in Australia that can do the test but that is even more distant for us than to send mail to the U.S.

Shoot I can't remember for sure but it was what Dr Nash @ the CT clinic requested for my visit - typing and lewis factor?

She choose to believe the blood test versus the saliva test when I saw her today.

Oh! You're the one with the two different results! See? I'm not crazy! I knew someone had posted way back in 2007 and said that they had gotten two different results right around the time that I had mine done.  

Well I re-did my secretor status just to make sure, via saliva.  My results are "Secretor"

I also had a saliva test say secretor, a serotype (Lewis test) said nonnie and then a second saliva test that said nonnie.

Here's a site in the UK that apparently does Lewis blood testing as well as Secretor Saliva testing.  I haven't used them so can't comment and I'm not sure how it would work with regards to your being in Sweden.  Perhaps you could contact them to see.

I had the lab do the Lewis test. But I already knew I was a nonnie, because I was getting allergic reactions to non-nonnie food.

Mayflower...even though you still came back with secretor, maybe you're 'borderline'...as you're craving those nonnie foods?
I'm officially secretor but feel that I'm more nonnie than secretor because of the foods that suit me etc.
Just my opinion of course.

I hear ya Janet, I've always been kind of sickly for a secretor growing up. My mother always had me at the doctors for colds throat infections...and I had my tonsils removed at 6 years old.  
I was disappointed that the results only said secretor but not to what degree.    I suppose the blood test would say to what degree.  The member that asked about saliva who turned out one way and the blood test that turned out the other way was told that the saliva is more accurate.  I still have a hard time with tomatoes.. I crave them.

Not at all, it was safflower oil. I bought a  rice milk that contained it and broke out in rashes. It's neutral for the secretor but avoid for the nonnie.

I have already been in contact with them but they don't do the saliva test. It seems like the only way for us in Europe is to send the test sample overseas. It might go faster to send the saliva sample with mail from Great Britain than Sweden. I'll probably wait until I travel somewhere near the lab.

I did contact Tom Greenfield but he says that they only carry out Lewis tests in their lab and that they currently send any saliva samples to the U.S. for analysis.

So for now it seems like there is no lab in Europe that can do this test.
