What does o2 negative mean?
A person with type O blood can only accept type O in a transfusion, but any blood type can accept type O in a transfusion. They are universal donors. this is because they don't have A or B antigens on the surface of their red blood cells but they have both anti-A and anti-B antibodies.
How many people in the world have RH negative blood?
15% of people in the world are rh negative...i happen to be one of that 15%
Why is the red cross important?
Founding of the Red Cross is important for many reasons. They collect blood donations from donors so that hospitals have a supply for blood transfusion and other things. Also, more than 1 million Red Cross volunteers and 30,000 employees mobilize relief to families affected by more than 67,000 disasters and they train almost 12 million people in lifesaving skills.
Why there is no effect when a rhesus negative man marries a rhesus positive woman?
In the cross between an Rh positive man and and Rh negative woman, the following possibilities will result:The child is Rh negativeThe child is Rh positiveIn the former case, there is no issue since the Rh of both the child and the mother are alike. There will be no problems during the gestation period.The the latter case however, when the child is Rh positive, there is a good chance the mothers immune system will begin producing antibodies against the child's red cells. Keep in mind there is intermixing of fetal and maternal blood at the placenta. This situation is not a big concern either. The mother is given immunosuppressant and the child survives.If the woman gets pregnant for the second time with an Rh positive child, the mothers immune system will not fight against the fetus and result in hemolytic disease of the new born. Erythroblastosis fetalis is an example of this.
What blood types do other animals have?
Animals have many different kinds. The number of blood types vary throughout each different species. For example, cats have 3, cows have about 800 and dogs have 13 (6-8 of which are the major ones). This is why blood transfusions cannot be made to different species. The donors blood will react to the patients blood because their blood types are not the same.
How many blood types are there how blood type is inherited?
To the second question the answer, in short, is YES; To answer the first question, there are four logical blood types: A, B, AB, and O. Then there is the Rhesus factor: either positive or negative. So there are actually eight types of blood a human can have: one of the above types with a negative Rhesus factor or with a positive Rhesus factor. Rhesus factor is a factor which compares human blood to a Rhesus monkey's blood. A negative result means your blood is not comparable to a Rhesus monkey. Blood types are inherited from your parents. If one parent has type A+, and the other has a B-, your blood type can either come out as A, + or -, or B, + or -, or the rare AB, + or - but not O. While type O negative is the universal donor, type AB positive is a universal recipient.

How many people have A blood type?
less than 15% have negative blood type . or rh- or without the rhesus monkey gene . i wonder where the the people without the rh gene came from ?
Why O-ve can transplant to everyone what is special?
O negative blood type is referred to as the "universal donor", however this applies to blood products only. Tissue transplantation is a more complex case requiring the matching of several different factors referred to as major and minor histocompatibility complexes. This answer will only approach blood transfusions as the immunology of tissue transplantation is extremely complex. Human red blood cells possess a particular marker on their surface (a glycoprotein know as the H antigen) which allows the body (specifically the immune system) to recognize them. There are 3 versions of this marker and we term them A, B and O. The A and B forms are modifications of the O form which is shared between all 3 types. As the O form is common to A, B and O blood types it will not be recognized as foreign within the body. The negative refers to the Rhesus type which is a separate marker on the red blood cell. In this case, some people have the marker (Rhesus positive) and some do not (Rhesus negative). If the Rhesus factor is present on blood cells that are given to a person who does not naturally express the Rhesus factor their body will reject those cells. If however the blood cells do not have the Rhesus factor, there is nothing to recognize and they will be accepted by the body. There are many other antigens on red blood cells which vary between individuals however the H antigen and the Rhesus factor are the most important. In a person who has never received a blood transfusion it is satisfactory to match only these 2 markers. People who have had previous transfusion however may have built up immunity to other less important antigens. These patients require more extensive cross matching of any blood they are to receive to prevent rejection.
Can blood donors be paid?
If compensation system helps encourage more people to donate, why not? Just don't let people think they can abuse this system.
Outcome when blood type A transfused blood type O?
If a person with blood type A receives blood from a person with type O blood, nothing bad should happen. Of course, this is not the end of the story; there is also the matter of whether the blood is "positive" or "negative". On the other hand, if a person with blood type O receives blood from a type A donor, the recipient will reject the type A blood. This is because of tiny proteins on the surface of the individual red blood cells. People with type O blood do not have these proteins, and so their red blood cells do not cause an immune reaction in the recipient's body. The same is true of the so-called "Rh factor" - the "positive" or "negative" part of blood. People with "negative" blood lack the Rh "antigens" or proteins, and will not cause immune reactions in other people. For this reason, people with "O-negative" blood are known as "universal donors", meaning that they can donate to anyone without causing problems. This makes them highly sought-after by blood banks because their blood is useful to many people.
How does goup o negative get a donar?
They must receive type O negative blood, which many hospitals store as universal donor blood.

Is 0 positive blood type common?
O positive is a very common blood type. It is the most common blood type today. There are not many people with O negative. O negative is very rare.
