Well you have to do blood typing.
ABO are blood groups & the test is to identify what blood group does the individual has
If he or she left some traces then yes it would help.
control group
control group
There is no special procedure to follow for a group B recipient to get group O red cell transfusions. There are no A or B antigens present on the donor red cells, so no ABO incompatibility.
Blood typing procedure wherein the antibodies are determined rather than the Antigen (Direct Typing). Uses pool A cells and pool B cells.
Blood type grouping is very important because if infection occurs then the wrong grouping was used and then we have a problem. Transfusions, etc. It is essential to correctly identify the blood group.
In1915, Leone Lattes, an Italian forensic serologist, developed a (reliable method) for determining the blood group of dried blood samples.
Blood type should only HELP to identify mixed up babies. There are only 8 possibilities and some are much more common than others. The probability of having the same blood group as the guy next to you is extremely high. Someone's blood group alone cannot PROVE anything. One would have to have genetic analysis to definitively check paternity...and even that is not exact (i.e. if the potential parents are brothers etc..). You can only EXCLUDE based on blood group...i.e. if the baby is a blood group that is an impossible combination from the parents in question. Baby's blood group can never verify that person X and person Y are the parents....only who the parents could not be.
Blood group A can donate and receive blood from blood group A. Blood group B can donate and receive blood from blood group B. Blood group AB can donate only to blood group AB and receive from any other blood group (they are universal recipent) Blood group O can donate to any other blood group ( they are universal donor) and can receive from only blood group O.
