Every individual has a unique DNA profile. Thus using DNA profiling it is possible to determine if the blood samples belong to the same or to different individuals. If the DNA profile of one blood sample matches exactly to the DNA profile obtained from the other blood sample, this means that the blood sample comes from the same individual. Only identical twins have the same DNA profile.
