What are the differant types of blood?

Answer 1

First, let me point out that there are 32 blood-group systems identified in the human. Each of these can affect the outcome of a cross-match for a blood transfusion. However, it would be too confusing to identify yourself as a 32 part blood type, so we limit it to the two most important antigens/genes which are the ABO gene and Rh factor.

The usually identified blood types are:

• phenotye: Type A pos = genotype: AA or AO with Rh factor (++) or (+-)
• phenotye: Type A neg= genotype: AA or AO with Rh factor (--)
• phenotye: Type B pos = genotype: BB or AO with Rh factor (++) or (+-)
• phenotye: Type B neg = genotype: BB or AO with Rh factor (--)
• phenotye: Type O pos = genotype: OO with Rh factor (++) or (+-)
• phenotye: Type O neg = genotype: OO with Rh factor (--)
• phenotye: Type AB pos = genotype: AB with Rh factor (++) or (+-)
• phenotye: Type AB neg = genotype: AB with Rh factor (--)

Therefore, there are 4 ABO blood types combined with 2 Rh factors, for a total of 8 blood types that can easily be identified with a blood mixing kit.

Answer 2

There is the ABO blood system which contains Type A, Type B, Type AB and Type O blood. These depend on which Antigen you carry (A or B). Also blood is known as positive or negative and this is determined by presence or lack of the Antigen RH.

Answer 3

The blood types are A, B, O with positive or negative annotations next to them. So for example we have (A-, A+, B-, B+, O-, and 0+). Type O- is the universal blood type that can donate to any of the other types.

Answer 4

You can talk to your doctor or local blood donation agency about finding out your blood type. The type of blood are A, AB, B, O and each has rh positive or rh negative (8 types total).
