If the answer is "no", here are 3 options to find out:

1) contact your physician or a hospital you have been treated in. It may be on file.

2) donate blood. They will tell you.


3) Google "blood type testing kit" and order one.


Just because a doctor doesn't tell you your blood type, doesn't mean he doesn't have it. If your blood type was ever tested for medical reasons, it will likely remain accessible.

If your doctor doesn't want to tell you your blood type, consider switching physicians.

Once you know your blood type, you can register here.
