There are six types of blood type. Blood type A, B and O, all of these blood type can be positive or negative so giving the total number of blood type to be six.
The four main blood types are A, B, AB, and O. Each blood type is determined by the presence or absence of specific antigens on the surface of red blood cells. Additionally, blood types are classified based on the presence of the Rh factor, resulting in positive or negative blood types.
The 1898 discovery of the four blood types (A, B, AB, O) did not directly lead to the discovery of the Rh factor, which was identified later in 1940. The discovery of the four blood types laid the foundation for understanding blood transfusions and paved the way for safer and more successful blood transfusions in medicine.
The four blood types are A, B, AB, and O. Blood type O is the universal donor because it does not have A or B antigens on its red blood cells. Blood type AB is the universal recipient as it does not have antibodies against A or B antigens.
There are actually more than four - if you include the positive and negative antigens... A+, A-, B+, B-, AB+, AB-, O+, and O-
The four basic blood types are A, B, AB, and O.
Blood types go into four major categories. Them being-Group A, Group B, Group AB, Group O.The most common blood type is O positive.

All four of the basic blood types can be either be positive or negative, they are A,B,AB, and O. Blood types are used to used define each person blood, they help to make blood transfusions more successful by matching up the blood types.

There are eight types of blood. The blood types can be either A, B, AB, or O. Each one of these blood types can be either negative or positive. So you would have A- or A+, B- or B+ and so on.
There is four types of blood in humans A B AB and O.But in each of them types there are a possible of at least 20 genetically blood vgroups known today.
Their are actually a few different types of blood a human can have. These are the different types: - A - B - AB - O Information Source:http://en.wikipedia.org/wiki/ABO_blood_group_system
