Aloha,
I remember reading something about when you donate blood you can request a test that confirms secretor status.  Im so challenged on researching past posts so would like to know.  I am going today to test for a rare blood antigen.

Whether you can get this done depends on where you donate bood. In most donation centers, you are not able to determine secretor status by donating blood.

Isn't there another way of telling by getting Lewis status or something?

serotyping panel, for a fee perhaps

we can help you decipher results

Not where I give blood. You have to go through a Hematologist to get one...then they follow up with the saliva test.

NYBC (New York Blood Center) doesn't do the Lewis typing, which is the blood test that can be used to determine secretor status. I called up and asked- if I want Lewis typing done, I would need to get my doctor to order it and then figure out which labs can do it (which may or may not be the same labs that my insurance will cover.)

If you're going to test for rare blood antigens, then the Lewis typing may already be included, or it may at least be available at the same location.

I gave blood today at a Red Cross Drive and they don't do Lewis typing.  I asked, hoping to confirm that I really am a secretor.  At the time I did my spit test, I was have some issues with my teeth and I've always wondered if I should redo it or have a full serotype panel done.  I was surprised today.  Most of the people I asked didn't even know what a Lewis type was.  The nurse there did and said she didn't think they tested for that, even though I donated "double reds."
