Strange Facts About Rh Negative Blood Type Origins

Individuals all over the world are unique in different aspects, and we are aware of the fact that people have different blood groups as well. Generally, we hear about having different positive & negative blood groups, but most of the people rarely know about Rh negative blood type origin and Rh negative bloodline. Also, there is a lot of confusion and misperceptions regarding Rh negative factor among humans. Several people think that Rh negative is an alien blood type. Some people think that having Rh negative bloodline is a kind of illness or abnormality, which may lead to several consequences. In this article, we will provide various strange facts about Rh negative blood and discuss some interesting information on the subject.

Rh negative blood origin

Rh negative blood origin involves a highly interesting story behind its name. Rh blood group was discovered around 60 years back by Karl Landsteiner who isolated rhesus factor from the blood of rhesus monkey, afterwards the same rhesus molecules were observed in human beings as well. Hence this way Rh was named after rhesus macaque monkey. Later RH blood group was ranked as the second most important blood system after ABO and an important factor within the area of transfusion among humans. Currently, the complexities of Rh blood antigens cannot be neglected since any kind of error in the process of blood transfusion in this reference can be fatal. It is due to the fact that Rh negative bloodline can signify the presence of antigens and the status of being immunogenic.

An Intelligible Odyssey About Rh Factor

Very few people know that Rh factor is a kind of protein that is inherited in blood cells. It is present at the surface of red blood cells. We can simply understand the difference between Rh positive and negative factors. If Rh protein is present on the surface of red blood cells, it means that the blood is Rh positive. On other hand, if Rh protein is not present in the blood, it will be referred to as Rh negative blood type. It is a misconception that being Rh negative is some kind of illness. Instead, there is no effect of being Rh negative on human health. However, for pregnant women with Rh negative blood, extraordinary care may be required in the case, the baby has Rh positive blood.

Rh negative is not an alien blood type

A person who is born from a mother who had Rh positive factor from both her parents will inherit Rh positive. Similarly, if the parents of the parents had Rh positive blood, there would be no possibility that the child would be Rh negative. This way, as a chain activity, Rh positive is transferred from generation to generation. It can only change, if a person marries someone with Rh negative blood origin so there can be a possibility that the baby can be Rh negative.

One of the rarest blood groups in the world

Some interesting statistics about the presence of RH negative trait shows that it is very rare around the world, that's why it is perceived as an alien blood type. As a whole, its presence in Europe, Canada, and the USA is 15%, while in Africa, its presence has been recorded between 25 to 35% which is the highest in the world. In the peninsula around 18 to 30% people have Rh negative blood origin, which is also a high proportion. However, no one could find any evidence about any connection between the possibility of Rh negative factor and race. If we talk in the context of the donor population, people with this blood group represent only 1.5% of the donor population, which further confirms the rarity of this blood group.

Rh negative blood type may be a risk for pregnant women

Very few people know about why pregnancy among women with Rh negative blood can be a risk. If the fetal cells have Rh positive blood cells, whereas the mother is Rh negative, then Rh sensitization will occur in the body. In this case, the body of the mother and her immune system will treat Rh positive fetal cells as an alien subject, generating antibodies in mother's body to fight future exposure to Rh positive blood. Once sensitized, the body's immune system will recognize any future Rh-positive cells as foreign and attack them.

If Rh-positive blood from a fetus gets into the bloodstream of a woman with sensitized Rh-negative blood, the woman's immune system will reject the pregnancy by attacking and destroying the invading cells. This is a dangerous natural blood response, because such reaction may hinder blood circulation to the baby's red blood cells. The gynaecologist needs to undertake necessary blood tests to identify possible contradictions in the beginning of pregnancy.

On timely diagnosis, the risk for the fetus can be minimised in advance. On the contrary, if the problem is not identified and addressed on time, then this blood incompatibility can lead to potential complications in pregnancy. The physicians can prevent blood incompatibility by timely diagnosis, otherwise, children with such incompatibilities may born with unpredictable complexities, such as mild to severe anaemia, raised bilirubin levels or jaundice. Mostly these complications are fatal, but even if a child survives during pregnancy and birth, he will be extremely ill after delivery. Therefore, in a case when the mother is Rh negative, and the father is Rh positive, the expert gynaecologist must be consulted to make sure that these complexities are addressed for the birth of a healthy child.

A source to advanced immunization

Rh negative blood is considered as alien blood type; however, it should not be considered as a disadvantage for humans having this blood type. It is interesting to know that Rh negative people have an enhanced level of immunity against parasites known as toxoplasma. The parasite is a silent invader in human body, which causes brain damage, lung damage and eye diseases after entering human blood. Therefore, the people with Rh negative bloodline have an advantage over others, that they have stronger immunity against toxoplasma. Scientists are also conducting research to find if Rh negative individuals are also resistant to other parasites or viruses, but there is still a lot more to be explored and verified. A unique fact regarding the impact of toxoplasma has been found, which identified that Rh negative males could have much more rapid reaction as compared to other people.

Rh negative factor is a key in blood transfusions

Many people may not know about an interesting fact regarding a particular Rh negative blood group, which is known as O-negative. Interestingly, this blood group is compatible for individuals having any of the blood group, either Rh positive or negative. In case of emergency, when the exact match is not available, people with O negative blood group can donate their blood to mitigate life-threatening emergency. This is because blood cells present in Rh negative group don't have any antibodies to A&B or RH antigens. Due to this characteristic, people having O negative blood group are considered universal donors since they can donate blood to anyone with any group, whether Blood group A, Blood group B, Blood group AB or Blood group O itself.

A & B negative blood groups also have a wider range to cover as a donor because people with A negative group can donate blood to people having A or AB group. Similarly, B negative can be donated to people with B or Ab.

But Rh negative people cannot have other donors

Although these findings are highly helpful for people, we might need blood donation in any case of emergency; however, it is also a noteworthy finding that Rh negative individuals are themselves deprived of this facility. In case of the need of a transfusion, Rh negative individuals have to face great trouble because the frequency of individuals with RH negative blood group is very low around the world. That is why any kind of emergency with the need for a blood transfusion can be a nightmare for the people who are Rh negative. This is because their body can only accept the blood group same as their own, which is the most crucial disadvantage for these individuals.

Is Rh negative really a reptilian blood and blood of the gods?

Strange, isn't it? There has been an interesting myth about Rh negative blood type origin. Some people think that it is originated from reptilian blood. However, there is no reliable evidence to prove this perception. Rh negative blood origin has no relation with these kinds of stories since this is an ordinary characteristic, which may be present in any individual, just like people may have different variations in Rh positive blood group. Or we can also say, that people may have different blood groups, either negative or positive, just the way they can have different eye colour or hair texture. It has nothing to do with the reptilians or extraterrestrials, but it is only connected with human DNA, which is uniquely transferred.

Being RH negative is just an ordinary difference between different individuals, which comes from their inheritance. These kinds of myths may be even stronger when the child with a positive RH factor dies during birth or pre-birth when born from the mother with a negative RH factor. But there is a very rare understanding that this is only because of a blood compatibility conflict within the immune system of the mother, not because Rh factor is reptilian blood as stated in the myth.

Overcome these myths and enhance your knowledge!

Various myths and misconceptions regarding Rh negative aliens are mostly spread because people are not aware of these things. Although there is a little understanding about different blood groups. However, different confusions in this reference give rise to interesting stories. For example, associating the reptiles with Rh negative alien does not have any logical explanation. That is why it is difficult to identify Rh negative blood type origin in the context of these stories. This is the main reason; it becomes difficult to understand why people who are apparently the same have different dimensions of RH factor. For example, many people may get confused when they get to know that their child has a different blood group as compared to their own group.

By studying the logic about how blood group is allocated to a human being, it becomes easier to find that anything is possible in genetics. However, no expert has ever been able to predict the blood group of the coming child on the basis of the blood groups of parents. Understanding Rh negative factor should be common now, and people need to stop perceiving Rh negative bloodline as an abnormality or lack of an obvious characteristic. This is to make sure that having a negative blood group is just a normal thing, which does not create any kind of abnormality or complexity. Only the case of RH negative pregnant mothers may be an indication of complexity. Though, this issue is also not complex for sure, and in all cases. Yet, to avoid any possible problem, people need to know about the necessary precautions. That's why, it is important for them to test blood groups of mother and father before conception of the mother.

In this article, you have found strange facts about Rh negative blood, which are gathered for you to enhance your knowledge to avoid general misconceptions. This is a natural phenomenon, neither an illness, nor a deprivation. Although risks related to fetal death and new-born mortality are quite significant due to blood type incompatibility. However, Rh factor provides higher immunity against toxoplasma, which is a parasite that silently enters the human body to cause brain damage. So, on one side, it has a risk factor but on the other side it is an advantage. These findings are quite interesting because as a general observation, people have a misconception that Rh negative may be weak since it has the protein missing. But by exploring the characteristics, Rh negative blood group are found to be more advantageous because they show greater compatibility with other blood groups. Most interestingly, please note that Rh negative has not been originated from reptilian blood, it's just a myth.
