Must be tested: Simplest way to learn, as long as you are healthy and do not think you have any infectious diseases / std, is to donate a unit of blood through the red cross. They will test your blood and send you a donor card with your blood type on it a couple weeks after you donate. You will also save 3-4 lives with your donation and not have to pay for test!

If you know your type, especially if you'r o negative, then please donate blood.
