Dadamo Secretor Status Collection Kit - US Only

One saliva sample tells you whether you're a secretor or non-secretor, for good.

Here's the thing about secretor status: it's not something you can guess by looking in a mirror, flexing, or checking your horoscope. It's a genetic trait that determines whether your ABO blood type antigens show up in your saliva and other bodily fluids, and the only way to know for sure is to spit into a tube and mail it somewhere. Which, when you think about it, is a strange amount of trust to put in the postal service. But here we are.

What This Kit Actually Does

This is a home saliva collection kit designed for people following Dr. Peter D'Adamo's blood type research, most famously laid out in "Eat Right 4 Your Type." Your secretor status is one of the missing pieces of that puzzle. It's a simple, non-invasive way to collect a sample at home and send it in for lab analysis, so you can round out the genetic picture you're already working from. No needles, no waiting room, no small talk with a phlebotomist about your weekend plans.

What's In the Box

• Sterile saliva collection tube and materials
• Step by step collection instructions
• Prepaid mailer for shipping your sample to the lab (US addresses only)
• Everything sealed and ready to go, because nobody wants to hunt down a tube at 8am

How It Works

You collect the sample at home, following the included instructions to the letter (this part is not the place to improvise). Once it's sealed up, you drop it in the mail using the prepaid mailer, and the lab does the rest. Results typically come back digitally, giving you your secretor status as a piece of information you can use alongside your existing blood type profile. It's a straightforward process. The hardest part is remembering not to eat or drink anything right before you collect, which is a surprisingly personal request from a cardboard box.

This kit supports a more complete personal wellness picture for anyone already working within the blood type framework. It does not diagnose, treat, or predict anything about your health beyond the genetic trait it's built to identify. Think of it as one more data point, filed away next to your blood type, your shoe size, and whatever else you know about yourself. US addresses only, since international mail and biological samples have never really gotten along.
