AB positive blood grouping suggest the person has both A and B antigens in the serum. It is a considerably rare group with a worldwide prevalence of only 4%. Blood type is determined by the nature of antigens carried by the red blood cells, which are inherited from the parents. Knowing your blood type is extremely important for both medical and genetical.
How Is AB Positive Blood Type Determined?
ABO Blood Type Calculator
Determination of blood type of child requires the knowledge of the antigenic composition of parents. If you know the blood type of both parents, the blood type of child can be determined by this simple chart. Similarly, if blood group of mother and the child is known, the blood group of father can be easily ascertained.
For example, if the blood group of mother is A and the blood group of father is O- the baby may either have blood group A or O; however, if the blood group of mother is A and the blood group of father is AB +, the baby will have either of the blood group A, B or AB.
Positive and Negative Blood Type
The blood type of positive or negative is inherited separately from the ABO types. An Rh negative gene can be masked by an Rh positive genotype. So, if a person is of Rh positive blood, he can still have an Rh negative gene. Moreover, if both of the parents are of Rh positive blood, their child can be of Rh negative blood.
| Blood Type | Genotype (DNA) |
|---|---|
| Rh + |
(+ , -) or (+ , +) |
| Rh - |
(- , -) |
AB Positive Blood Donation
This chart below will serve as a basic guideline to help you in knowing what blood type can be accepted by AB positive blood body and what blood type may elicit a reaction.
| AB Positive Blood | Who can donate blood to you if your blood type is AB +? | Who can receive the donation of your whole blood (or RBC concentrate)? | Who can receive platelets from you? | Who can receive plasma from AB + donors? |
|---|---|---|---|---|
| AB + can receive blood from any blood group (like A, AB, B and O) |
Unfortunately, AB + blood group is referred to as Universal recipient (suggesting that your RBC concentrate can only help the recipients of same blood group i.e. AB + |
Since platelets do not carry any antibodies or antigens, virtually all blood groups can accept platelets from AM+ donors. |
Anyone can receive serum from AB+ donors since serum does not contain any anti A or anti B that may create the problem for recipients. |
AB Positive Blood Diet
The antigenic composition or blood type also determines what type of foods can be consumed by the person. When compared to other blood types, those who have AB blood type need to maintain extra caution with their diet. This table below shows the foods that are healthy for AB positive blood type and nutrients that should be avoided.
| Foods | Comments | Most Beneficial | Allowed | Not Allowed |
|---|---|---|---|---|
| Meat and Poultry |
AB + individuals are incapable of secreting gastric acid in large amounts. It is therefore suggested to avoid/ minimize the intake of animal proteins. |
Rabbit, mutton, lamb and turkey |
Almost all the foods except the nutrient sources listed in the next column |
Chicken, quail, duck, pork, beef, hen, goose, pork, veal, venison and Cornish |
| High intake increases the risk of malignancy of gastrointestinal tract. |

You can consume from a variety of Echinacea, Chamomile, Alfalfa, burdock and Green tea |
Black tea, Soda beverages and Distilled liquor |
