BTD Forums  /  Live Right 4 Your Type  /  how accurate is secreter test?
Posted by: iolanif (Guest), Wednesday, September 27, 2006, 9:11pm
Of the 4 people I know on this diet we all turned out to be non secretors.  This seems crazy to me seeing as only 20% of the population are nonnies.  Do they make mistakes at that lab?  I'm just having a hard time beliving it.  Any responses would be appreciated.

80% of Dr Ds patients are nonnies!!

Here's what Dr. D has to say in regards to the Lewis typing vs saliva testing:

Quoted Text
"Having done 5000 Lewis typing tests in the clinic over the last 15 years, and about 400 salivary inhibition studies, I can safely say that saliva testing is more accurate than blood. The reason being that the agglutinations that are used to determine Lewis types are very delicate (weak antibody reaction) and can easily be misinterpreted, unlike ABO which makes a big glop that you cannot miss (strong antibody). I've even seen conflicting results from two different MedPath labs, especially if the staff is not trained well enough." The subject is discussed in more depth in one of the Science Knowledge Base Entries


We have a big nonnie (slang for non-secretor) presence on the forum, even though they're a small part of the population.  Nonnies usually have more health issues that secretors, and as Dr. D has said himself, they make up approximately 70% of his practice.

iolanif-it is the most accurate secretor test there is from my understanding.  Also, from my understanding, if there is to be a mistake in the secretor testing it is more likely that a nonnie will be mistakenly tested as a secretor due to sores or bleeding in the mouth at the time of the test.  And...it is the nonnies that are the ones that are most likely to be sick because we handle bacteria from within. Someone correct me if I am wrong please.  ;)

Debra :)

P.S. 80% secretors and 20% non-secretors...4 of you tested nonnies...do you realize how many billions of people there are in the world? ;)

Well then if we don't know our secretor statis shouldn't we follow the non secretor diet then???

You have a much higer percentage for being a secretor than a non-secretor.  80-85% probability.  

If you are burdened with health issues, then it's recommended to find out, to fine tune your diet so that you can experience results faster.

If you are unable to test, then consider eliminating foods that are conflicting between secretor/non-secretor (in other words, AVOID the avoids for secretors and nonnies) until you can test.  That limits your food choices more, but at least you know you would not be eating avoids.

I was stunned to learn I was a nonnie, but eliminating Ononnie avoids and adding in Ononnie bennies & neutrals helped my health issues improve more, over their already-improved BTD state! (Amongst other things, discovered oats make my joints hurt! Who knew?!?!) The test definitely was worth saving up for!

iolanif,

Look around this board at how many of the regulars are confirmed nonnies.  It's much higher than chance.  Nonnies are much more prone to having health issues; often ones that allopathic medicine does not deal with very well; and thus they are the ones who seek out alternative solutions.

Ok, Ok That makes sense I was looking more at percentage and probability.  i'm still shocked with our results.  I don't mind it, I can have tomatoes woo hoo! Its my hubby that's the problem, no spelt no cheese!!!! Cooking is much more of a challenge now:(

Is it also becuase nonnies are more opinionated, wackier, 'talkative', etc., therefore more likely to go on line & opine about whatever?
I still suspect I am one!

It made a lot of sense once I learned I was an A nonnie! It was well worth the 40 bucks to find out.

people bock at the price of the test and the fact they have a low percentage of being a non secretor but this proves it pays to know...you can't put a price on it

I just received the news today that I'm a non-secreter.  About 6 months ago I'd posted and complained that I just didn't feel as good overall as I did when I first began the BTD and about a dozen people wrote back and said that I needed to have my secreter status checked.  Finally dished out the money.  Looking foward to seeing if it helps any.  A little nervous about trying tomatoes.  I know I react very badly to peppers and potatoes but haven't had tomatoes in a year and a half.  I'll try them as soon as I get over this horrible bronchitis and keep my Deflect handy!  Ohhh, the idea of having spaghetti sauce again is >>>unbelievably<<< attractive.

Hi Ribbit!

I hope following the nonnie diet makes a difference for you.  Remember, concentrate on the beneficials, and make the neutrals the rest of the meal.
Posted by: Ribbit, Friday, December 22, 2006, 8:56pm; Reply: 15
Yeah, it's easy to eat a bunch of neutrals (especially for protein) with two other blood types to have to cook for too.  We end up eating a whole lot of turkey and I tend to forget about tofu until my toddler pulls a carton out of the pantry and hands it to me.  He likes to eat it by the handful straight out of the box.  :)

My mom's secretor test just came back, saying that she's a secretor.  But that doesn't make sense....

She's always been insanely sensitive to carbs just like I am.  She's always had nothing but problems with her teeth, which have required countless amounts of dental work.  She's also had numerous bouts with candida.  

I just don't understand it.  Could her test have been mis-handled?

Hi Ronagon,

Could she be Lewis double negative? LDN secretors are recommended to follow the non-sec diet.

Also, being a secretor doesn't necessarily imply good dental health, there could be other (even genetic) factors involved.

Cheers,
Yaman

How old is your mom, and what is her Rh status?  How many mercury fillings has she had?  How does she do on the fingerprint test?  Your mom sounds like me, and I'm a secretor.  I've eliminated about 99% of the grain in my diet.

Same here--I'm a secretor and eat almost no grains (rice, millet and an occasional slice of spelt or ezekiel bread being the exceptions). I'm extremely sensitive to simple starches and sugars of all kinds and tend to stick with small amounts of beneficial meat and fish, and lots of bennie veggies as well as some fruit. I also take supplements like nettle leaf, Rhodiola and a good B complex vitamin, and drink rooibos tea or mineral water. As I've said before, I'm a nonnie in every way except secretor status! :)

You will notice on this board (and it has also been very noticable on other BTD forums I have frequented) that nonnies are way overrepresented.  As has already been pointed out, despite being only 20 percent of the population, nonnies make up 80 percent of Dr. D's patient.  Nonnies are prone to more health problems . . . and, particularly those types of problems that are difficult for traditional practitioners to treat.  So, if they ever get around to testing blood types, secretor status, etc., in a big way, we are probably all quite confident here that any study will find that people who spend time studying nutrition (beyond the food pyramid), seeking out non-traditional solutions, etc., are overwhelmingly non-secretors.

In general, secretors do much better even on a Standard American Diet until it catches up with them in the 60s and 70s.  In general, non-secretors will start having health problems (or just don't feel very well) sooner and search for solutions.

What about Intestinal Permeability  (Leaky Gut Syndromes). It causes all sorts of health problems. Worth looking into.

That is called being Type O.  Being an O nonnie just kicks it to insanely sensitive notches unknown.  But O-ness alone is enough to cause insane sensitivity to carbs.

I'm a non-secretor with GREAT teeth.  ...Gums are another story, but teeth are great.

Does she eat a lot of refined starch and sugar?  That'll do it!

Good question.  I guess you know the general recommendation is the opposite.  But some have switch to the non-secretor diet when they didn't feel much difference on the secretor plan . . . even without the test.

It's just the weirdest thing... both my parents are secretors, yet I'm a non-secretor.

And as far as my mom being a lewis double-negative, I would have no earthly idea how to test for that.  The only thing I can tell you is that she might have the fingernail ridges.  Her diet has been terrible, all her life, and her mouth, poor thing, is all filled with dentistry.

Lewis Double Negative (LDN)
A small section (1-4% of the population
dependent on race) will be Lewis Double
Negative (LDN; Lewis (a-b-)) and for which
Lewis typing cannot be used to determine ABH
secretor status. In these individuals
determination via saliva is necessary. However,
it may be helpful to think of LDN
individuals as a special category of non-
secretor, since they do lack the Lewis b
antigen (like the traditional ABH non-
secretors). In most instances LDNs share the
same metabolic consequences as ABH non-
secretors, and in a few, such as
cardiovascular disease and insulin resistance,
actually have the most severe variations."


Lewis a-b- (Lewis Double Negative-LDN), the secretor status remains unknown. An LDN can be secretor or non-secretor.

Lola,

Yes, but how do you TEST for Lewis?  That's not possible with just the saliva test, is it?

Hi Ronagon,

Lewis test is a blood test.

You can get the Lewis typing done by the Southwest College of Naturopathic Medicine.

They can also testing for the following:
ABO type
A1 or A2 subtype
Rh +/-
Lewis type
MN type

You should probably make sure you have a way of getting the blood drawn before ordering the test kit. Some people have said they haven't found anyone to do it, at least without a doctor's lab order.

Where else in the country can this testing be done? The web site implies there are a few.

It's a nonnie epidemic!  :oI just received my results, and I too am a nonnie!  I was very surprised, due to my extreme headache reaction to dried bananas. But... as I read more about the health problems experienced by nonnies, thick blood, dental cavities, ulcers etc. I said "that's me!" Time for some dietary tweaking!  ;)
