Know Your Blood Type (group, genotype, rhesus factor)


During my PhD research field work, one of the children that was a subject in my clinical trials was very sickly and wasn’t responding well to treatment. The infant was subjected to a blood test and that was when it was discovered that the child’s genotype was SS.

Right there in the hospital upon knowing the outcome of the test the father of the child made it known that his relationship with the mother of the child was practically over since he could not try having another child with her. Even though nurses tried talking to him about the possibility of managing the boy’s condition I could notice his change in attitude at subsequent clinic appointments compared to how loving he seemed initially.

Save yourself the stress that can be caused by ignorance my friend. Make sure you know your blood type.

Sometimes ago, I asked a lady what her blood group was and she said “S”.

I ask you too today, “What’s your blood group, genotype and rhesus factor?” There is a difference between your blood group and your genotype.

It’s very important to know what they are (so you identify the red zones). Before you go too far with that man, towards marriage, go for a blood test together. (There is a recent case of a man who lied about his genotype to his fiancee. They got married and the truth was revealed when one of their children started falling sick because he was a sickle cell carrier). So be watchful.

Ignorance can cost you a whole lot. Be sure that your blood types are compatible. And that the combination of your blood types would not give your child a problematic blood type. Love is not blind at all.

Ignorance has led to some women loosing pregnancies over and over (and thereby labelled witches) not knowing that it is was just a case of differing rhesus factors.

Ignorance has led to poverty and lack of peace in some homes. Knowing your blood type also matters when it comes to blood transfusion.

If your genotype is AS, I beg you in the name of the Lord, don’t marry someone whose genotype is also AS or worse still SS or SC (except you are very sure that the Lord Himself has assured you of safety on that road). Think of the children you will have. The pains that sickle cell carriers go through is unbearable. Spare those children please.



And spare yourselves the horror too. I tell you, having sickly children will test that love you say is the reason you are marrying that person and damming the consequences.

Research results show that there is some evidence that certain components having to do with fertility can be shown to be under the influence of blood type, in particular, the level of antibodies a woman secretes into her vaginal tract that are directed toward other blood types can be shown to be under the influence of secretor status and diet. The rejection of the man’s sperm can often be the result of blood type incompatibility (Dr D’Adamo).

In case of emergencies too, the knowledge of these details about yourself would come in handy

The Blood groups: A; B; O; and AB. Group O is the universal donor(they can give every group blood). Group A can donate to A’s and AB’s. Group B can donate to B’s and AB’s. AB can donate to AB’s but can receive from all others.

Your blood type is inherited from both of your parents. Each parent carries TWO “alleles” for both blood group and Rh factor, of which only ONE is passed to each offspring. What alleles they possess constitutes their genotype. Some alleles dominate over others. For example, a parent with type A+ may have 2 “A” alleles, or, they may have one A and one O. In the latter case, the O will be dominated by the A, and that person will be blood type A, but can still pass the O trait on to a child. Similarly, a person who is Rh+ may have either two + alleles, or one Rh+ and one Rh-, with the Rh+ dominating. Again, in the latter case, they may pass either an Rh+ or Rh- allele to their child.

An A or B allele will dominate over an O, so if your genotype is AO, you will be type A, and if it is BO, you will be type B. People with both an A and B allele have type AB, since neither dominates the other. Since the O allele is recessive, people with type O blood will always have the genotype OO. The Rh+ allele dominates Rh-, so a person with a positive Rh factor may be ++ or +-. Those who are Rh negative are always –.

Knowledge is power!
