D'Adamo Personalized Nutrition Home Blood Type Testing Kit

I wish I'd been warned it was time-sensitive. I was taking too long to get enough blood, and then it didn't work. (I assume taking too long was why it didn't work.) One of the circles had agglutination right away, but by the time I was done getting blood in each circle, and I'd stirred each, the agglutination no longer showed and none of the circles had agglutination. I did add a little more water to each at one point out of fear it would evaporate before I was done, but it didn't seem like too much water--maybe that's (also?) why it didn't work.

Was quick and easy (after reading instructions) and gave results we needed. Thanks for a great
product!

Really easy process. Took maybe 5 minutes. Results were instant.

I am so happy I bought this! I was wondering what blood type he was because I’m an O positive and our children are all A positive, so I told him he was definitely an A positive and I was RIGHT! I was so happy that this confirmed that for me!

Had a problem with first one and they sent another immediately. Works as advertised.
