Blood is grouped into four types: A, B, AB, and O. Each type is also classified by an RH factor – either positive ( + ) or negative ( - ). When a blood transfusion is necessary, donor and patient blood must be compatible. If not, the patient’s body will react to the incompatible donor cells, leading to complications, maybe even death.

Your ABO blood grouping and Rh factor are inherited from your parents. Check the chart below to see what percentage of the population shares your ABO grouping.

O +    37%          O-    6%
A+    34%          A-    6%
B+    10%          B-    2%
AB+    4%          AB-    1%

When you donate, United Blood Services will send you a card with your blood type. Whatever type you are, someone in the community can benefit from your blood donation. Donate today. You’ll feel terrific!

Lol @Dguy's Comment.   Ma 'G'  that can never happen in Our Medical field.

I answer to the question is YES. In blood grouping, we have two types blood grouping called Positive and Negative, in other word refered as Rhesus "D" blood grouping. Understanding your type is essential as many people ignorantly faced complications as a result of reaction. We have the following:
A+
B+
AB+=(Universal Receipient)
O+ =(Universal donor)

A-
B-
AB-=(Universal Receipient)
O- =(Universal donor)
Note: The universal donor and receipient are applicable to their respective group ie Positive or Negative respectively.

GROUPING: DONATION
A+ = A+only
B+ = B+ only
AB+ = A+, B+ AB+ only
O+ = A+, B+, Ab+, and O+. That is why its refered as Universal Donor. It donAte to all of the same R"D" type.

RECEIVING:
A+ receives from O+, AB+ and A+ only
B+ receives from O+, AB+ and B+ only
AB+ receives from O+, A+, B+ and AB+. = It receives from all of the same Rhesus "D" type.
O+ receives from O+ (itself) only

This formular is equally applicable to Negative blood grouping.

NOTE: Avoid the combination of both positive and negative i.e O+ = O-

However, the only condition for both combination includes:
1. if the patient posses a Negative blood group and the type could not found at the point of death
2. if the patient is a male child
3. if the patient is a female above or has stop given birth, otherwise the female will not conceive.

I have grab a lot

so join me pls

In my lil medical understanding, the (-) is kind of a problem o esp in women vis. conception/child birth complications.

Summary: U can have just one child with rhesus factor

With due respect, I think you got your facts a lil twisted. O+ ppl can only give blood to another O+. He CANNOT give blood to ppl with type A or B blood group due to the Rhesus factor. Only O- can donate their blood to all other blood groups. That is why it is called the Universal Donor. Those with AB blood group on the other hand are known as universal Recepients becoz they can receive blood from all other blood groups. Coming to think of it, it is the O- people who need to be more cautious as not many ppl have O- blood. O+ ppl are rather lucky. Nowdays many are O+. I am O+ myself n i have lotsa ppl i know who are O+. Lucky for me.

Hi....

There is no prb in tat. My mum is B+. Dad is O+ n everything worked out fine for me . Ur children may either follow ur blood group or your husband's. If you need futhur clarification or second opinion, i advice tat u consult ur physician. God Bless n all the best.
