Which, if any, of the blood samples tested can be patient with Type B+ blood recieve?
seropon [69]

Answer:

Type B+ can only receive blood from a donor that has blood type B and AB with Rhesus positive or negative.

Explanation:

The blood group system classification is based on the presence or the absence of antigens on the surface of the red blood cells. thus the blood group system is divided into four main blood group types/antigens present. During blood transfusion, the donated blood must be compatible with the patient blood type.

In blood transfusion, patient who is Rh positive can receive blood from donor who is Rh negative, but those with negative blood types cannot receive from anyone with a positive blood type but only the Rh- blood.

Donors with blood type A can donate blood to recipients with blood types A and AB

Donors with blood type B can give blood to recipients with blood types B and AB

Donors with blood type AB can donate to recipients with blood type AB only

Donors with blood type O can give blood to recipients with all blood types A, B, AB and O.
