The ABO blood group isn't the only one. In fact, there are about 34 different human blood groups. Now, scientists in Nature Genetics have explained the genetic basis behind a rare blood group called Vel. Vel Blood Group Most people are Vel+ (Vel-positive), meaning that they possess the Vel antigen on the surface of their red blood cells. However, about 1 in 5,000 individuals are Vel- (Vel-negative), and thus do not carry the antigen. Their immune system recognizes the Vel antigen as foreign, and if given Vel+ blood, they can experience kidney failure or possibly death. A screen currently exists for this blood type, but it can be inaccurate; therefore, identifying the blood type's genetic basis will allow doctors to more easily screen patients.
Blood group AB is very rare and although AB blood types are able to receive any type of blood they are not able to donate blood to persons that are not blood group AB. Type O negative blood is considered the universal blood type. People with type O negative blood are called universal donors because type O negative blood is compatible to any blood recipientâs type. Ideally the donorâs blood types should always be an exact match to the recipientâs blood type. Universal donors should only be used in the case of medical emergency where there is an unavailability or shortage of the patientâs blood type or when a blood transfusion needs to be performed immediately, not allowing the time to cross type the blood ...
