Then in the 1960s scientists developed RhoGAM, a key drug that helps protect babies born to moms with Rh-negative blood (thank you, science). If you don’t know you’re blood type, the blood center will test your blood when you donate and let you know your blood type. It wasnt until the early 1900s that we learned about different blood types due to some people dying from blood transfusions. But what about an unexpected medical emergency? That’s when O-negative donors save lives! Interested in finding out what blood type you are? If you’re scheduled for a surgical procedure, you can always donate your own blood in advance and be given that during the procedure. What does this mean for you if you have O-negative blood?īecome a blood donor! If you have O-negative blood, you can only receive O-negative blood, so you want to help ensure that there’s always a good supply on the shelves. But this also means that people with O-negative blood can only receive O-negative blood. For example, Mayo One helicopters each carry a cooler with three units of packed red blood cells with O-negative blood and three units of thawed plasma. This means that it’s missing those things that could cause a bad reaction during a blood transfusion and can be given to any blood type. And because of that fact, type O-negative blood is often used in emergency situations. O-negative blood is missing both the A antigen and the B antigen and does not contain the protein for Rh-positive blood. This gives us the common blood types of A+, A-, B+, B-, AB+, AB-, O+, and of course O. You are positive if you have the protein and negative if you don’t. Your Rh factor is determined by whether or not your blood contains a specific protein. Blood types are either positive or negative, depending on the absence or presence of the Rh factor’s D antigen, another marker. Type O: Red blood cells have neither A nor B antigens. Type AB: Red blood cells have both A and B antigens. Your blood group is determined by whether you have the A antigen, the B antigen, both A and B antigens or neither A or B antigen. Type B: Red blood cells have the B antigen. That led to safer blood transfusions because doctors transfuse the right type of blood for people need to survive. The existence of the antigens that determine if your blood is O, A, B or AB was discovered about 100 years ago. If you have O-negative blood, the only blood type you can receive is O-negative. Can the O negative blood type diet improve overall health The O negative blood type diet emphasizes whole, nutrient-dense foods and limits processed and potentially inflammatory foods. While those with O negative are universal blood donors, the blood they can receive when it comes to transfusions is far from universal. I’m O negative, what type of blood can I be transfused with?ĭo you have O-negative blood? If so, you may have discovered that your blood is needed by hospitals and emergency services to help save lives, but you may be wondering what type of blood you can be given if you need a transfusion.
