Yes, AB negative is the rarest blood type.
Explanation:
The presence or absence of certain antigens on the surface of the blood cell (called A or B for the group, and D for the subgroup) enables the blood to be typed as A, B, AB, and O, and as Rh positive or negative. See the link below.
Of these, all the negative groups are rare, and AB negative is the rarest blood type, occurring in less than 1% of the human population.
