Blood typing might not seem like a glamorous thing to do, but if you've always wanted to know your blood type without having to go the usual route (donating blood, doctor), you can do it yourself at home! The process is simple, you take a drop of blood and see how it reacts to the boxes on the card provided. The best part? The kit comes with a laminating sheet so you can carry the card with you, wherever you go - along with your dried blood, of course.
