It has been discussed many times in the LR4YT board. Have you learned how to use the search feature yet?

Also, I think you might want to spend some time here: http://www.dadamo.com/science.htm

In fact, most of what you need right now is probably in here: http://www.dadamo.com/knowbase/newbie/a.htm

I first had a serotyping panel done, to determine MN status, as well as RH, and (subtypes of A, had I been an A), and Lewis results....
turned out being a L(a-, b-), meaning a strange bird LDN...

so I had to do the saliva test to confirm my LDN non secretor status

Quoted Text
Dr D
"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 search feature Lloyd proposed is a great help, to further your BT/GT knowledge, needed to spread the word properly.

How about this -- someone give me the search terms I would have used to find this information. None of the terms I tried gave me anything worthwhile.

Thank you Lola.  You must, of all people, know how difficult it can be to wade through reams of text to find the answer to one simple question.

DGale,
I also wonder about that search engine sometimes.  No matter how I change the settings, older newer than 10,30, 90 days, some words, all words, it comes but ziltch, zero when I know I have seen those topics before, but where?

Regarding the blood or saliva secretor tests, I am sure I read somewhere maybe even from Dr D himself that he favour the saliva test or that the saliva test was more accurate and that may be why he went to all the trouble of making it available to us all? but where?

I used my very own term and status, LDN!

Lewis typing or simply lewis would have given you lots of hits
saliva testing, as well

are you using the main search feature on the website main page?
I find it incredibly accurate!

The Search tab above this.  
The imperative word is 'sometimes'.  Sometimes I get excellent hits and get what I am looking for.  May be our lack of experience with the terminology of it all is something to be patient with and where we may be needing most guidance...  With your valuable help, we all get there ..  It is not the lack of trying though ... This is a wonderful place to try and grow ...

So t is not the engine ... Now where is that book?

Thanks Christina. It's difficult when others appear to think we newbies sit here typing up questions w/o looking for the info first. How many pages and paragraphs will most people read before asking a question that has surely been asked before?
I bet I'm prone to read far more than the average person, and still...

There's using the search engine, and then there's navigating the website filled with gems of information - neither an easy task.

We can always count on Lola.

The search function in e-blah software is a bit weak.

Certainly try there and see if you find what you want.

But you may want try searching this site with google, when you do not.
To do this use the search box on the homepage:

http://www.dadamo.com/

Or this direct link:

I agree. That's why once someone has reached a certain participation level we hope that they can learn the means to find the basic answers to help both themselves and others.

who decides when someone has reached this "level" ?

Brains can work very differently even at best function. Some of us are operating with damaged brain cells.

Thanks C_sharp.  Well said, e-blah search is a bit blah.  I find I can only search once (very slow) and then trying another search the Search button can't be pressed again  

There's many ways to navigate to the whole website search.  You can go to http://www.genotype.com (read great tip of the day)
Click on Support
Then there this page comes up http://www.dadamo.com/support.htm with a great search button up the top.    

It searches the whole website, so you can find Ask Dr D, blogs, forums and more.  K'ching! Goldmine of information

you can also click on website and get the great search button you mention

the search button in the forum is limited to the forum only, and the forum gets purged ever so often....

Forgot to say.  You can browse the forums by going to Forums tab then choose the appropriate forum.  

The Live Right for your type forum is where all the non-secretor info and more lifestyle topics would be.  There are forums for non-BTD GTD topics too, even a nonnie clubhouse but they let secretors join in and suspected nonnies too .

Sorry DGale - you probably already know this since you've been on the SWAMI forum.

I would have to say that the Lewis test is more accurate. I first did the saliva test which turned out to be non-secretor. At about the same time I also did the Lewis blood test which turned out to be secretor. Colour me surprised. The saliva test was done with NAP4EU (called Stacktheme back then) and the Lewis test was done with Dr. Tom Greenfield's company. I had some email conversations with both Nick Bowler of Stacktheme and Dr. Tom about the discrepancy. I don't quite remember what the exact outcome of those conversations was, but it was pretty inconclusive. (This must have happened about 8 years ago right after LR4YT came out.) Anyway, some time later I sneakily re-did the saliva test under a different name (but again with NAP4EU) and this time it said I was a secretor.  
That's why I would probably do both to be on the safe side.

Interesting, Tom O! I frequently question my non-secretor status so maybe will go for the blood test just to confirm.

Probably a good idea, Teri. You'd need Lewis blood group anyway if you ever wanted to do SWAMI. (Optional field, though, not mandatory.)
