This difference has probably stuck around because it has some good points too. Mom just has an ordinary DNA difference that can have bad effects on her pregnancy.
As if the mother and child are from different species.īut they're not. HDN makes it look like the mother is rejecting the child. This is called hemolytic disease of the newborn or HDN. This can cause the baby to get very sick or even die. When an Rh negative mother is pregnant with an Rh positive child, the mother's immune system can attack the baby's blood. But some people think it must be special because of the effects it can sometimes have on pregnancy. So being Rh negative isn't any stranger than having blue eyes or red hair. No, being Rh negative did not come from aliens or gods. There is no need to invoke aliens, gods or reptiles. And when we look at Rh negative and Rh positive people, we see the usual kind of difference. We have different traits because of small differences in our DNA. There is DNA that controls our hair and eye color, our blood type and most everything else about us.
Remember, DNA is the instruction manual that makes us who we are. So, where do these sorts of differences come from? They come from our DNA! In this way, it isn't any stranger than different eye or hair colors. In fact, Rh negative blood is an ordinary trait that some people have and some people don't. However, there is no evidence to support this. In the case of Thomas, the man cited in the Mosaic article, his Rhnull blood was due to two random mutations in his genes.What an interesting question about Rh negative blood! It would be very cool to think that our human ancestors bred with reptiles and/or gods. The risk of having Golden Blood is higher in families where there has been consanguineous marriage (marriage between cousins, brother-sister, or anybody who is a near or distant relative). Rhnull appears to be the result of a genetic mutation, and these mutations can be passed down through families. Given how highly it is prized by doctors, it was called Golden Blood by Dr Thierry Peyrard, Director of the National Immunohematology Reference Laboratory in Paris. Golden Blood is also in high demand, because their blood is universally compatible with any rare blood type within the Rh system, meaning it has immense life-saving capability. People with Golden Blood are encouraged to donate for themselves, with the blood being stored in case they should ever need it. Given how few people have Golden Blood, finding a donor is extremely difficult. People with Golden Blood can only receive transfusions from other people with the same condition, because otherwise the Rh antigens on the donated red blood cells would cause an immune reaction. Blood transfusions for people with Golden Blood The red blood cells themselves may be less elastic and the overall blood volume of the individual may be altered. This lack of all Rh proteins can cause mild to moderate anaemia, with faster than normal destruction of red blood cells, leading to paleness and tiredness.
A 2014 article in the magazine Mosaic looked at the case of a patient, known as Thomas, who had Rhnull blood, with the article titled: “The man with the golden blood”. In the 1960s a type of blood was discovered that was not only RhD- it had absolutely no Rh proteins whatsoever. In reality there are 49 different proteins in the Rh system, and whether someone is Rh- or Rh+ in fact only refers to one of these, RhD (which is the most significant for transfusion purposes).
In total the four blood groups, with each being either Rh- or Rh+ give a total of eight main blood types, which can be transfused as follows. People with Rh- blood can give to both Rh- and Rh+ recipients. The Rh protein is an antigen, being something that triggers an immune response. the blood is Rh+, and that blood is given to someone who is Rh-, the immune system of the recipient will identify the protein as dangerous and will create antibodies against it, attacking the transfused blood. If this protein is present the blood is Rh positive, if it’s absent, the blood is Rh negative. The Rh factor is a protein found on the outside of red blood cells. In addition to these blood is also analysed as to whether it has Rh factor or not.
The four main blood groups are A, B, AB and O. The blood types themselves are based on the presence or absence of different molecules on the surface of the red blood cells. He was awarded the Nobel Prize for Physiology or Medicine for his work in 1930. In 1901 Karl Landsteiner, an Austrian biologist, physician and immunologist, identified the blood types, A, B, and O, with the majority of them being incompatible, with just a few drops of blood from a non-compatible group leading to rejection of the transfer, illness and even death. Up until the 20th century nobody knew why some people died after a blood transfusion while in others the receipt of blood from a donor caused no problems.
