YOGYAKARTA - In general, there are four types of blood groups, namely A, B, AB, or O. Each of these blood fields was followed by a negative and positive category. In addition to the four, it turns out that there is a term golden blood type. This blood group is called a rare blood type.
The golden blood class is the rarest blood type in the world. In fact, only less than 50 people have this blood type. The golden blood type is also called Rh-null or blood type that does not contain antigen Rh (protein) in red blood cells (RBC).
So what is the type of gold blood, what are the characteristics and differences with other blood types?
Lang Blood Groups in the World
So far, we know the rare blood type as AB. But it turns out that the golden blood type is the rarest in the world. The golden blood group was first identified in an Aborigin woman in Australia.
People classified as gold blood are difficult to receive blood transfusions because they do not have an antigen Rh. The owner of this blood type usually always crosses with other blood owners Rh-null, to ensure the availability of blood when needed. Owners of this group can only see the same type of blood transfusion.
Characteristics of Owner of the Gold Blood Group
A study says the gold blood type is the result of a genetic mutation (spanish changes in the gene). This condition is usually seen with mutations in the RHAG gene, which codes for glycoproteins related to the RH.
People who have gold blood type have health vulnerabilities in certain diseases. RHAG mutations are often associated with herediter stomentosis or blood disorders that are passed down from genetic factors. Gold blood disease can suffer from long-term hemolithic anemia, mild, and increased blood cell damage.
Owners of the gold blood type are also likely to have mild to moderate hemotic anemia from birth. This condition causes people with Rh-null to be easily exhausted and pale due to low hemoglobin levels. In addition, other health conditions that can occur include abnormal red blood cells, leaking membranes, to a short life span.
Causes of Gold Blood Group
A rare blood golonga called the golden blood type can be caused by several factors. There are people who are at high risk of having gold blood. First, because of blood marriage. Second, because of the autosomal gene ( abnormal gene that is passed down genetically). Third, change or complete elimination of certain genes (named RHD and RHCE or RHAG).
Gold blood type owners have more concerns than the general blood type. Rh-null's contribution to gold blood is very difficult to obtain or rare. If they receive blood that has antigen Rh, it can lead to a transfusion reaction.
But on the other hand, this blood type can contribute to anyone who has a rare blood type in the Rh system.
Those are the rare types of blood in the world that not many people know. The condition of the scarcity of blood is what makes it called the golden blood type.
