crossmatching
No. Determining the ABO blood type of a blood donor is only the first step. Rh is tested also. Donor blood also undergoes major testing for diseases transmissible through blood. The next step is looking at the recipient and their needs as far as "matchability" for a blood and blood product transfusion.
crossmatch tests
Blood tests have to be done to determine a match.
The heart must come from a person with the same blood type as the patient, unless it is blood type O negative. A blood type O negative heart is a universal donor and is suitable for any patient regardless of blood type.
In order to accurately determine blood type, blood must be drawn from the donor. This means that only a doctor or assistant can accurately tell a donor what blood type they have.
A blood donor is a person who donates blood for use in transfusion.
Its blood donor and it means u donate blood to someone who needs it.
It can be. Like any other type of transplant, there are compatibility issues that need to be analyzed to determine compatibility. Cord blood from a non-relative (and a relative as well, the only time HLA-typing is not required is an autologeous transplant) will be HLA-typed to determine compatibility before any transplants are performed.
Blood type can be easily determined by going to any hospital, some local clinic might have the facility too. Also blood donor banks can figure this out for you.
the correct form is donor as in a blood or organ donor.
Blood type O is the universal donor.
