Welcome dave!  You can get a testing kit from the NAP store (I got mine from http://www.right4eu.com because I'm in UK) which can be sent off to the lab for testing.
I found it very easy (and quite fun as a friend and I did them together) and helpful.

The sectretor test kit ordered from NAP is the least expensive and best way to find out. An alternative is to do a Lewis blood type test, which will give you the answer the vast majoity of the time.

Dave,

I was wondering if there was a way to tell secretor status by what foods have a bad reaction. For instance, if sugar makes you sick, does that mean you're a non-secretor? -- that sort of thing. I haven't read enough to know if that's even possible, but it sounds like it might work to me. Maybe somebody who knows will chime in...

You cannot determine secretor status by what foods you react to badly or positively.  The only ways to determine secretor status are to order a saliva testing kit, as Mouse described, (which you can do easily from NAP, by going to the tab up top on this page labeled "The Store") or by getting a blood test (as Lloyd described in his post).  If alcoholism runs in one's family, there is a good chance that the non-secretor gene does, too, but there is no way to tell if you are a non or a secretor other than to actually get tested for it.

:)

This is kind of what I'm doing, since the NAP secretor test isn't available in NYS. But it's not really accurate. Basically, I'm avoiding all foods that are "avoids" for secretors and non-secretors, and trying to eat beneficials for either one (so long as the food is either beneficial or neutral for the other secretor type.) So far, I haven't done well on any foods that are "ok for secretors but not for non secretors" when consumed in large-ish quantities, but neither have I had any obvious problems with any of those foods when used in teeny tiny amounts- as condiments, small amounts of "avoid" spices, etc. Half a goat-milk cheesecake over the course of 2 days = "brain fog". A teaspoon of tamari in my  chicken stir-fry = no problems.

Remember that it's possible to be allergic or sensitive to a food that's otherwise OK for your blood type. Just because a certain food doesnt' agree with you is NOT a guarantee that it's because of your secretor status.

There is one other clue, and it has to do with whether you are prone to cavities or not.  I need to find my Live Right book, but I think that non-secretors tend to have more cavities, and secretors usually have pretty strong teeth.  At least I think this is true for type O's....I'll go check.....
I just looked in the LR4YT Book, and it's in the charts at the front of type O, but not in any other type (B,A or AB) that non-secretors may have more dental problems.  It has to do with levels of IgA
antibodies.  I guess after looking at this, it is still really guessing.  So having the saliva test is a great idea.

YEah, if you go by the dental health clues, I must be a secretor. I had no cavities for about 20 years, but then I had a few at my last checkup.

But if you go by foods, I appear to be a non-secretor.

See, Ruthie, it's confusing if we try to guess, but the test is pretty straightforward....but until one is able to swing the test, you can do your best at experimenting.  My teeth are a bit crooked on the bottom, but pretty strong.  I wouldn't have guessed secretor though.  Now for the genotype, I have been experimenting....until I can swing the trip to the clinic.... ;)

A test is the only sure-fire way to know, but I don't see anything wrong with experimenting if money is really tight.  Of course, budgeting it in would be best, but you can always try the secretor diet first for a while, then switch to the non-secretor diet and see if there's any difference.  You know, just to see.

My daughter did better on the "nonnie" diet and so we assume she a nonnie.

As far as teeth go......I'm a nonnie, but I have great teeth.

There are two problems with budgeting it in:

1) I'm on a limited income, in debt, and haven't received child support in months. I really don't have any money to put aside right now- if anything is spare, it goes towards the Visa bill so I can pay it off ASAP and pay less interest. The only reason I have CC debt at all is because of the child support- I needed to buy things like clothes for my kids and didn't have the cash.

2) It's illegal to mail saliva out of New York State. Getting the secretor status done would involve travel to another state (and the expenses involved with that) in addition to the cost of the test itself.

There really aren't all that many differences between the nonnie diet and the secretor diet. Most foods have the same values. A few nonnie beneficials are secretor neutrals and vice versa. A whole bunch of foods that are neutral for secretors are avoids for nonnies- I'm doing my best to avoid all of those foods. There are only 3 foods that are OK for nonnies but not secretors (not counting things I wouldn't eat anyway such as legumes or non-kosher fish or meats)- avocadoes, avocado oil, and coconut oil. I don't eat those items either.

hope you get the same results as I did.....
I eliminated both avoids before I found out about my double lewis negative status!! ;)

I forgot which way it goes for O secretors and nonnies with Oats, but there was a difference I saw somewhere in the last 2 days.
It might be enough to force me to get a test.  Before it warmed up for summer I was eating oatmeal every day.
I just had blood drawn at my doctor's office and saw that he supports the blood type diet, but never thought of asking him if he can get the test done for me, and it is too late now.
Maybe next visit???

For the first three years of BTD I 'assumed' I was a secretor.   Had the test done and voila...nonnie.  When I did the first three years of BTD I had lost 80 lbs. and felt pretty darn good.  Still had bugs to iron out, but I was just thinking that because of all the c**p and damage we do to our bodies over the years I just needed more time to heal.    

And...actually, my first clue should've been my soft teeth and all the mercury in my mouth. (Which I am finally getting around to really getting out).  ::) :B   ;)

Debra :)

P.S.  Secretor test...worth every penny.   And I paid almost $150 Canadian five years ago.  About half the price now.  :D

Big Lulu...you can order a secretor test through NAP.  You don't need to go through your doctor.  :D

hello everybody!
I write from sweden so perhaps the spelling aint the best but hope you can overlook than and understand what I want to say!
Im trying to understand if Im a secretor or a non-secretor. To begin with I really dond quite understand what that is becausen when I did my blood test my result was "A RhD positiv" can annyone tell me if that test tells if Im a secretor or a non-secretor.

"A" is the ABO group
"RhD" is the Rh type in your case positive

Secretor type is completely independent of the ABO and Rh and must be performed as a completely separate test.

In Sweden as in the states you can get yourself secretor tested by requesting the Lewis blood group phenotying test from a blood donation center. But they will most likely charge a fee for the test.

Interpretation of the Lewis phenotypes is as follows...

Le(a-b+) is always a secretor

Le(a+b-) is always a non-secretor

Le(a-b-) can be secretors or non-secretors

Le(a+b+) are weak secretors and extremely rare

I was hoping to go by this clue at one point but in my case it was not the least bit helpful. I've never had a cavity in my life and as you can see I'm a nonnie  ;)

I have had some gum issues, but not due to disease, just a bad crossbite that I am in the process of having fixed atm.

gum issues are also typical nonnie! :)

I am sorry if I didn't correct that statement about cavities.....from going back to the Live Right Book, it looks like that is only true for type O secretors/vs. non-secretors, not the other types....if I understand correctly.

Yes I know Lola, but I think it is issues with gum disease. Right?

Not casued by tooth alignment like in my case.

no, it s more to do with recessive gums.....

Hmm, ok. I'm not sure I see how some of the causes of receding gums have anything to do with secretor status. Gingivitis I can see, but not the others like over brushing, naturally thin tissue or poor tooth alignment.  :-/

How long does the whole secretor testing take, from the time you order it, it arrives, you send it back, and they tell you the results?

Hi Dave,
Apparently you have to get a test kit to check your saliva. They run between $69 and $79. I am not a doctor, but I have been comparing notes on what ailments that secretors and nonsecretors have a tendancy to get, I can almost 100% tell that my father was a nonsecretor. He had adult onset diabetes and died of  a heart myocardial infarction. My mother does not show any signs of the diseases listed while being on a non O blood type diet.

For residents of the US (and some other countries as well), the saliva test is no longer user. The glycometrics test kit which uses a few drops of blood is used instead.

Price is about the same.

Information on this kit is here: http://www.4yourtype.com/prodinfo.asp?number=TE006
