What is Blood Typing and How is it Different from Blood Chemistry?

Someone recently asked me a great question:


What is Blood Typing and How is it Different from Blood Chemistry?


The most succinct answer is that Blood Typing tells you your ABO blood group and Rh factor … and that Blood Chemistry tells you your biochemistry. But, what does that mean in plain English?!


As we all know, people have different types of blood. This is important because some types of blood are not compatible with others and a transfusion of incompatible blood can be fatal.


The plasma membranes of red blood cells (RBCs) have highly specific glycoproteins at their external surfaces. These glycoproteins act as antigens that induce an immune response, like the production of antibodies. If you are given blood from an incompatible blood type your RBC antigens will mount an immune response to destroy the foreign RBCs.


According to my favorite Anatomy textbook by Elaine Marieb “There are a least 30 common varieties of naturally occurring red blood cell antigens in humans. Besides these, there are perhaps 100 others that occur in individual families (“private antigens”) rather than in the general population. The presence or absence of each antigen allows each person’s blood cells to be classified into several different blood groups.” The antigens determine the ABO and Rh blood groups.


The ABO Blood Group System as Described by the Red Cross:


There are four major blood groups determined by the presence or absence of two antigens (A and B) on the surface of red blood cells:


  • Group A – has only the A antigen on red cells (and B antibody in the plasma)
  • Group B – has only the B antigen on red cells (and A antibody in the plasma)
  • Group AB – has both A and B antigens on red cells (but neither A nor B antibody in the plasma)
  • Group O – has neither A nor B antigens on red cells (but both A and B antibody are in the plasma)


In addition to the A and B antigens, there is a third antigen called the Rh factor, which can be either present (+) or absent ( – ). In general, Rh negative blood is given to Rh-negative patients, and Rh positive blood or Rh negative blood may be given to Rh positive patients. Most Americans (about 85%) are Rh positive.


  • The universal red cell donor has Type O negative blood type.
  • The universal plasma donor has Type AB blood type.


The + and – symbols after your blood group designate if you are Rh positive or Rh negative. For example:


If you have A+ blood this means that you have A antigen on red cells, B antibody in the plasma and the Rh Factor is present.


If you have A- blood this means that you have A antigen on red cells, B antibody in the plasma and the Rh Factor is NOT present.


To see an awesome interactive chart that illustrates the donor to recipient blood groups go to the Red Cross website.


More on Rh factor


Rh factor is important to know about because if an Rh- person receives Rh+ blood, the immune systems becomes sensitized and shortly after the transfusion it will begin to produced antibodies against the Rh+ blood.


We also keep track of Rh factor because women with Rh- blood that become pregnant with a baby that has Rh+ blood will start to make antigens against the Rh+ blood of the fetus. These women can usually bring their first Rh+ baby healthily to term; however if they become pregnant again with an Rh+ baby their bodies will attack the fetus.


There are at least 8 different types of Rh agglutinogens (antigens that promote “agglutination” or “clumping” of RBCs) that can make a person Rh positive. Being Rh negative is a recessive trait. What this mean is that if an individual has no functional Rh genes, they are classified as Rh negative. If a person inherits one Rh gene from one parent (Rh+), and one non-functioning Rh gene from the other parent (Rh-), they will be designated as an Rh+ phenotype. This is how two Rh+ parents can produce Rh- offspring if the offspring each inherit only the Rh- alleles.


I find Rh factor extremely interesting. It reminds me that there is still so much we do not understand about our bodies, our history and our origins. Current medical science simply cannot explain why some people do NOT have the Rh factor … it is literally inexplicable using our current paradigms of scientific inquiry.


There are a lot of interesting theories on the origin of Rh-negative bloodlines that cross the full expanse of the imagination encompassing everything from carbon dioxide clearance to genetic experimentation by Ancient Aliens or the bloodline of Jesus Christ. None of these theories can be proved at this time.


What we do know for certain is that Rh-negative people are found most predominantly in genealogies of Irish, Scottish, Basque, Western European and European Jewish descent. 


The least controversial and most commonly accepted scientific explanation is that the Rh-negative allele is a mutation that developed after populations migrated out of Africa to Europe; and that the Rh-negative allele is associated with a need to speed the transfer of carbon dioxide in and out of RBCs due to higher levels of CO2 in the region.


But, the truth of the matter is we do not know the origins of the Rh-negative phenotype … and that is OK.


To really have fun exploring the collective theories of Rh Negative Origins I recommend investigating The Rh-Negative Registry … enjoy!

To have even more fun exploring our hidden origins, history and capabilities I recommend exploring the programs on Gaia TV … or even better … READ THE BIBLE. Check out some of the playlists from Chuck Missler’s Koinonia House on YouTube … I can assure you … what you have been told about the Bible is very different from what is actually in the Word of God. Plus, reading the Bible will CHANGE YOUR DNA, seriously.



The Blood Type Diet


Personally, I do not recommend that everyone choose a diet based upon their blood group alone. The blood type diet is popular, very interesting and accurate about many physical aspects. And, I know from personal experience that it is too generalized to work for everyone. According to blood typing I should flourish on a vegetarian diet. In fact, I was a vegetarian for 10 years, not because I wanted to follow the blood type diet, but because a physician recommended vegetarianism when I had my first gallbladder attack. 


Over that 10-year period in which I was a vegetarian my health deteriorated immensely. And in my efforts to regain health and vitality I began studying nutrition and Kriya yoga with a passion. I can assure you, I was eating a “balanced” vegetarian diet.  Additionally, vegetarianism was very attractive to me at the time from a philosophical standpoint, but it did not suit my body in the least. I went from having gallbladder troubles to also having daily IBS, arthritis, psoriasis, anterior pituitary dysfunction, thyroid dysfunction, blood sugar dysregulation, adrenal fatigue, dental cavities and soft bloody gums. I was a mess! I was very uncomfortable and my body was weak.


So, let me just say this. Though the blood typing diet is fun to explore to see if your personality traits match those characterized by your blood group … in my search for wellness I found that there is SO MUCH MORE involved in determining what is the best diet for an individual than blood type alone. You also have to consider things like how your nervous system is wired, how your immune system reacts, what your genetic predispositions are and what epigenetic factors are acting upon your body.


This is where Blood CHEMISTRY can help illuminate how your body is functioning and responding to your environment and the foods that you are consuming. Blood CHEMISTRY reveals your personal biochemistry … it reveals the chemical and physicochemical processes that are occurring within your body at the time the blood is drawn.


Dr. D’Adamo who pioneered personalizing nutrition using blood type, has expanded and refined his work by combining blood typing with genotyping to produce more precise recommendations. If you have an interest I recommend exploring his website and books, they are quite interesting and his recommendations might work really well for you. If they do not, I recommend progressing on to Functional Blood Chemistry Analysis.

In Conclusion


Each person’s body is unique and highly individualized. I invite you to explore working with health care professionals that can help you discover the personalized nutritional balancing approach that works best for you. Remember, the healthier your body is, the happier your mind can be and the more uplifted your mood and vibration. Eat Clean!


Many Blessings to You Beautiful One, 

I am happy and honored to be here with you bringing Heaven to Earth and raising the mass consciousness together. Cheers! Vanessa
