There are more than other known antigens, the presence or absence of which creates "rare blood types." Certain blood types are unique to specific ethnic or racial groups. That’s why an African-American blood donation may be the best hope for the needs of patients with sickle cell disease, many of whom are of African descent.

NASA Kids is an excellent site for "kids" of other blood types ages and provides an abundance of information, images, and interesting things to do on astronomy and the space sciences.

In this lesson, students learn about sources of high-energy radiation and calculate student exposure to ionizing radiation over the past year. But there are actually 30 other ways to type blood, including two just identified by French scientists.

The latest are based on proteins called Langereis and Junior. Arnaud: Everybody on this planet are positive for this blood type. Except few of them. Extremely few of them.

These rare variations could explain why some blood transfusions go awry, even when the standard blood types match. And pregnant women who lack these proteins may also be at risk for miscarriages, if the fetus is positive. A common school science experiment is to try and determine your own blood type. Note: Don't assume your conclusion is accurate! You may also know your blood type from a doctors' visit or filling out medical forms.

These types indicate what kind of antigens, or proteins, are on the surface of your red blood cells. The positive or negative refers to a type of Rhesus protein, specifically Rh-D, and it may be present positive or absent other blood types. Blood typing is important because if you receive another kind of blood or tissue — for example, a transfusion or an organ transplant — it must be compatible with your blood type. Giving type B blood to a type A person, for example, would trigger what's essentially an allergic reaction to the blood, other blood types.

That's because the type A person's body would recognize the B protein as a foreign invader, just like a bacteria or virus. It would attack the B-type blood with immune cells called antibodies, other blood types, creating a serious and potentially life-threatening allergic reaction. However, other blood types you heard, other blood types, there are actually a total of 30 surface proteins that can vary from person to person.

Their names include M and N, Kell, Lewis, and others, often named after the patient in which they were first identified. The other blood types aren't as well known for one of two reasons: either the vast majority of people have one of the types therefore making incompatibility rareother blood types, or incompatibility doesn't usually cause significant medical problems.

In the case of the new blood types, Langereis and Junior, the first is true: until now, it was assumed that virtually everyone carried the proteins. But Arnaud's team found that there are small but significant populations that have Langereis or Junior-negative people — enough to classify the presence or absence of these proteins as a new blood type. As you heard, the negative blood types are found mainly in certain populations. Therefore, for example, it may only be important to check the Junior type in people of Japanese descent.

But knowing about these minor blood types could help explain some otherwise mysterious cases — other blood types instance, women who have unexplained miscarriages. An Rh-negative mother carrying an Rh-positive baby can develop antibodies that harm the fetus, but this is widely recognized and can be prevented with certain drugs.

When there's no Rh incompatibility, it's possible that a conflict in one of the lesser-known blood types could be causing the reaction.
