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.
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.
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.

which blood group can be donate to all other groups? "O" positive blood group. it's called universal donor.
If you are in the AB blood group, you can only donate blood to others in the AB group. You can receive blood from any group.
A or AB
Indira Gandhi's blood group was reportedly A positive.
Anti-M factor is an antibody that can be present in individuals with the M blood group, which is part of the MNS blood group system. It is formed in response to exposure to M antigen, typically through transfusion or pregnancy. In the context of blood transfusions, the presence of anti-M can lead to hemolytic reactions if compatible blood is not used. Thus, it is important to identify and consider the presence of anti-M in blood transfusion and organ transplantation scenarios.
Their children can have blood groups A or O.
