What Happens When Two Different Blood Types are Mixed Together?

Blood is packed with red blood cells.
Even though all human blood might look the same, there are actually different kinds called blood types.
Blood types are based on special markers on the surface of red blood cells. These markers, known as antigens, are made from sugars, proteins, and other molecules, and everyone has their own unique set.
There are several systems used to classify blood types...
The best-known are the ABO and Rh blood types, which are very important when it comes to safely giving someone a blood transfusion.
Today, we took a closer look under a microscope to see what happens when we mix blood from different ABO blood types!

I’m a B+, and my mother is a B-. We had an RH incompatibility, and my mother was given a tiny bit of my blood and some sort of medication in an IV in order to ensure that if she had any more babies, neither she nor they would be affected by RH Incompatibility. I’m sure that doctors do something more modern (or at least less bloody) now. I was born in the dark ages, otherwise known as the 70’s.

I am O- and my husband is O+. I had to get a rhogam shot while I was pregnant with our 2 kids, just incase they had my husbands blood type. They both got my blood type though.

[@danielcarlsen9228]

@G0L_D_Fsh Because if the child was O+ and some fetal blood leaked over the placenta, it would cause immunization in the mother resulting in antibodies that could pass back through the placenta and target the blood of the child which would be dangerous. The drug hides the surface marker on the fetal red blood cells thus immunzation does not occur.

[@mikepeterjack2132]

@G0L_D_Fsh because there is blood transfer between mother and child in the body and i think in this case there was a chance they were incompatible or something

[@foreverswiftie]

@G0L_D_Fsh in case of father being (-) and mother being (+), no complications are observed. But in case of mother being (-) and father being (+) and foetus (child) being (+), some of the blood (or antigens) mix with the mother's blood and she becomes sensitized. In subsequent conception, in absence of Rhogum inj. The foetus RBC is destroyed causing Jaundice and such

Ironically enough, there actually might be a scientific explanation behind the people with blood type O (supposedly) being gentler. Type O is the blood type of the original humans, the oldest one. Antrophologists have found evidence that when we were hunter gatherers, we were more egalitarian and gentler in general. With the rise of agriculture around 10 000 years ago, some people started accumulating more wealth than others and used that to have control over other people. the concept of authority and people ruling over others, as well as money and warfare, was born there. The diets changed as well as we started eating more grains, and the blood with it. And we started becoming generally more violent as well. It wouldn’t surprise me if people with type O blood also retained other genes from our gentler ancestors. (This is still mostly speculation tough so take it with a grain of salt)

Also, ABO antibodies (anti-A, anti-B) are formed naturally after being born. Rh antibodies (anti-D) are formed via exposicion like; transfusions or pregnancy (the mother). Just wanted to share what was tought to me recently. Love the video.

[@CoralineYann]

can you explain it a bit more? I like learning about biology :)

[@mati.benapezo]

Someone who recieved blood transfusion from a donor with a non compatible blood type, especifically the less common ones (low frecuency or non ABO) can develop antibodies from that, and then it gets harder for that person to receive any blood. Even if they share the same ABO group.

[@iranalmonte]

@@CoralineYann so basically we have many antibodies which our immune system makes to help us survive :). They are separated into different classes of antibodies based on their structure. So when we are born we are given genes from our parents. This includes our blood type. Everybody has a blood type; A, B, O or AB. This is the ABO system. It is the biggest blood system we know, and the most immunogenic meaning it causes us the most harm if there is incompatibility between the blood types. In our plasma we have antibodies to the other blood types that we DO NOT have. This occurs naturally from the day you are born you are predisposed to having those antibodies in your blood. There is nothing that we can do to change that. These antibodies are class IgM. We also have the 2nd most immunogenic blood system called the Rh system. This determines whether we have a + or - beside our blood type. If we have a positive beside our blood type this means we have the antigen (A+, B+, O+, AB+). If we have a - beside our blood type then we DO NOT have the antigen and are at risk of making the antibody. We do NOT naturally have this antibody in our system, meaning we have to be exposed to it to get it. We can get it through 2 ways, pregnancy or transfusion. This antibody is class IgG and CAN cross the placenta and hurt our babies. Hope that helps :)

2:50 Isn't type O universal donor, so shouldn't that be the reason that you didn't see much of a reaction

[@sumbody207]

But there was. He didn’t specify whether either blood was negative or positive. people with O- blood are universal donors whereas O+ blood are only compatible with other positive blood (A+, B+ or AB+). So what we might be seeing is a B- blood reacting with a O+ blood.

[@n-steam]

O-type blood contains anti-A and anti-B antibodies in the plasma. What you're seeing is the anti-B antibodies in the O-type plasma reacting with the B-type red blood cells. O- is a universal donor, in that it can donate RBCs to anyone. But it should be separated out before transfusing for no reaction to occur.

[@Human_ver-2.1.0]

O type is universal donor, not acceptor. ​@@n-steam is right

[@iranalmonte]

So basically we have whole blood which is broken down into 4 components: 1. Red Blood Cells 2. Plasma 3. Platelets 4. Cryoprecipitate To keep it simple, type O IS the universal donor. But this only applies to type O red cells. As another comment stated, the reason you saw the reaction was because he mixed whole blood not just red cells. This means that the antibodies in the Type O plasma reacted with the Type B red cells. Hope that helps !

[@angeladavies993]

O neg is a universal donor. As a 13yrold, I'm 72 now, my parents and siblings were asked to give blood when they were researching blood for the rhesus factor.

[@Darnetal57]

Since you mixed type O with type B, isn't it normal that there was little to no reaction visible under the microscope? I don't think it was because of the concentration of the antigens in blood vs in testing solution, but more that Type O doesn't have any antigens, so there's nothing for type B cells to react with. If you had a type A friend laying around and mixed his blood sample with type B friend's, you could probably have obtained a much more pronounced reaction.

[@souleymanesaid3968]
