Q: Good evening. Please I want to know much about blood group. If husband is AA and -0 and his wife is AA nd +0 and she didn’t take injection BTW that 72 hrs what is the solution
A: Everyone’s blood contains antigens and antibodies which form the blood’s defence against foreign bodies. The antigen and antibody present in your blood determines your blood group.
Your blood is made up of red blood cells (which carry oxygen round the body), white blood cells (which help fight infections) and platelets (which help clotting) suspended in plasma (a liquid).
Your blood group depends on genes inherited from your parents.
There are 4 main types:
A: People with this blood group have A antigen on their red blood cells and Anti-B antibodies in their plasma. Thus, giving this person blood from someone with blood group B will lead to the antibodies (anti-B) attacking that person’s B antigen.
B: People with this blood group have B antigen on their red blood cells and Anti-A antibodies in their plasma. Thus, giving this person blood from someone with blood group A will lead to the antibodies (anti-A) attacking that person’s A antigen.
AB: People with this blood group have A and B antigens on their red blood cells and but have no antibodies. People with this blood group can accept blood from any blood group as they have no antibodies against either the A or the B antigen.
O: People with this blood group have no antigens but have Anti-A and Anti-B antibodies in their plasma. People with this blood group can donate to anybody as they have no antigens.
Transfusion of the wrong blood group to anyone can lead to fatal reactions that can result in death.
Now to the Rhesus compatibility…those + and – signs at the back of our blood groups
Our red blood cells may also contain another protein called the RhD (Rhesus D) protein. If this is present on the surface of the red blood cells, the person is Rhesus D positive and if absent, the person is Rhesus D negative.
This Rhesus factors are particularly important in pregnant women. If a Rhesus D negative woman gives birth to a child who inherited Rhesus D positive gene from the father, then the woman must receive the anti-D immunoglobulin to prevent sensitization (a process in which her body sees her baby’s red blood cells as a foreign body causing her to produce antibodies to fight her baby. This is likely to occur during the separation of the placenta). In her first pregnancy, this is not a problem, because essentially her body just produces antibodies and your own immune system quickly gets rid of the circulating red blood cells in your body; but if she’s exposed to Rhesus D blood again, perhaps through another pregnancy, these antibodies are produced again and cross the placenta to attack the baby’s red blood cells and this can continue even after birth. If you and your baby have the same Rhesus factor, then there’s no cause for alarm J The other good news is, if your husband is the one who is Rhesus negative, none of your babies will be affected by Rhesus incompatibility.
So, I hope I got it all covered now 😀
Have a good night y’all 😀
