can you give rhesus negative blood to a rhesus positive patient?

Answer 1

Yes, you can give Rh neg blood to an Rh pos individual. A quick rule of thumb is that type O neg is a universal donor, meaning that anybody can receive it. When trauma patients come into the ER at the hospital I work in, we don't have time to type and screen their blood, so we have to give them O neg. There are many antibodies and factors in addition to A, B, O and Rh neg/pos, but these are the basics.
In contrast, the universal recipient is AB pos.

Answer 2

There are more than thirty different blood group systems. There are four main blood groups in the ABO system: A, B, AB and O. Each of these can be divided into rhesus-positive or rhesus-negative. People who are group O are universal donors; in a case of dire emergency their blood can be given to any of the three other groups, but they can only receive blood of the same type as their own. Rhesus compatibility is also important.

Answer 3

No not really. It's very important to get the right match of blood group whether it be A, B, AB or O.

The whole process involves antibodies.

There is one caveat to this, which you may have got from TV programmes like Casualty, Holby City, ER etc.

In an EMERGANCY you can try giving
O Negative blood to any patient, as it is the least likly to cause problems with antibody reactions. To this extent many operating theatres / Emergancy departments keep this blood in their departments for such use.

Answer 4

Yes because the term negative means that there is no cell inidcator on the blood cell. These cell markers (as in a positivie person) act as indicators for our immune system to recognize foreign blood and "attack" it. Therefore, since there is no indicator on the negative cell, it acts neutrally in positive blood. However, the opposite, giving positive blood to a negative person, would cause a reaction.

Blood type also needs to be considered. In the O, again, there is no cell marker. A and B both carry markers. Therefore, O cannot receive blood from A, B or AB, but they can give blood to anyone.

Here's a little chart

Can give to Can receive from
O+ Can give to O+, A+, B+, AB+ Can receive from O+, O-

O- Can give to anyone Can receive from O-


A+ Can Give to A+, AB+, Can receive from O-, A+, A-


A- Can give to A-, A+, AB+, AB- Can receive from O-, A-


B+ Can give to B+, AB+ Can receive from O-, B+, B-


B- Can give to B-, B+, AB+, AB- Can receive from O-, B-


AB+ Can give to AB+ Can receive from anyone


AB- Can give to AB-, AB+ Can receive from A-, B-, O-, AB-

Answer 5

Generally speaking, yes. But, the A, B,O must be matched.

Answer 6

No

Answer 7

no
