What type of blood can donate s man AB negative and explain?

An AB negative (AB-) individual can donate blood to recipients with AB+, AB-, A+, and A- blood types. This is because AB- blood contains both A and B antigens, making it compatible with those who have AB blood types, and it lacks the Rh factor, allowing it to be safely transfused to Rh-negative individuals. However, they cannot donate to O or B blood types, as those recipients would produce antibodies against the A and B antigens present in AB blood.
