  1. Ummm not sure why for every blood type starting with A – you finish the statements with ” 1 in every (different number) people are born with **** B- BLOOD **** followed by a percentage.

    ” B- BLOOD ” is in every statement from A- to A+. I am just a bit confused. Can you clarify.


    1. Don’t pay attention to the subject of what blood type is rare in all actuality all blood types are rare to a point. this list just lets the viewer see how rare their blood is compared to other people. Whats more important is who you can get blood from that makes you stand out. O+ can only receive from their own type or O-

  2. as far as i know i am RH-, now i am super confused all a sudden because i thought that was my blood type, but now what i am hearing is that i am either a, b, ab, or o -, how am i suppose to know which letter i am. all i know is that i am rh-, and every time i get pregnant i have to get a rho gam shot in my butt cheek and at the time of delivery, or else me and the baby can die or have to get a complete blood transfusion. please help me figure this out. thanks, confused in tacoma wa..lol

    1. Go donate blood, they’ll tell you your type 🙂 , or if you ever had surgery, that doctor can tell you your blood type

      1. you can have an Rh- blood type and not have type B blood. ABO is different from Rh. (see: anyone with A-, O-, or AB- blood.)

    2. It is because you have negative blood. RH negative requires the shot, when are having a baby, this is for any future births.

    3. RH factor is just what you become when you have negative blood and your baby has positive blood. i was AB- when i was pregnant and the father of my baby was 0+ so that made my baby AB+ so that is when the RH Factor came in. The Rh factor test is done during pregnancy to identify a woman’s Rh factor. In some cases, the baby’s father might need an Rh factor test, too.

      During pregnancy, problems can occur if you’re Rh negative and the baby you’re carrying is Rh positive. Usually, your blood does not mix with your baby’s blood during pregnancy. However, during delivery or certain times during pregnancy, a small amount of your baby’s blood could come in contact with your blood.

      If you’re Rh positive, Rh incompatibility isn’t a concern. If you’re Rh negative and your baby is Rh positive, however, your body might produce proteins called Rh antibodies after exposure to the baby’s red blood cells. The antibodies produced aren’t a problem during the first pregnancy. The concern is with your next pregnancy. If your next baby is Rh positive again, your body will produce Rh antibodies that can cross the placenta and damage the baby’s red blood cells. This could lead to life-threatening anemia, a condition in which there are not enough red blood cells. If this condition is not prevented, each Rh positive baby you carry after your first pregnancy might have severe anemia.

  3. I want to know what is the best foods to eat being I am a AB- blood type and what is the worse to eat, Can you please tell me I am a diabetic and I need to loss weigh like yesterday . please help I don’t have money to be buying pills I will go to grocrey store and buy the food I will need if some is wilong to tell me with out charging me.

    1. You need to see an 8 Constitution Doctor. Ecmed.org. Read the information. This type of Doctor will tell you exactly what body type according to your pulses, Organs, that you are. This exam provides a complete regimen on how to eat, what to avoid, how to breathe, excersize etc…Eating for your body type will create a clean, healthy, balanced body. Along with Tumeric, Alkaline Water thus staving off inflammation, bloating, Disease & maintain regular Accupuncture?? I am RH B- ?

    Just wondering – you state that the blood group AB Rhesus positive is the ‘rarest’ blood group; but in your listing it comes out as the ‘3rd rarest’ what then are the two rarest blood groups? Would be interested to hear and I also add to my blood group an anti-D.

    1. You cannot donate blood to anyother blood type because the antigens on your red blood cells will be denied by the recipients body. So if you donate to a type B recipient, then the type A antigens on your blood will be rejected causing problems. Same thing with type A recipients. You can’t donate to O because it doesn’t have any antigens, so it will reject your blood altogether. The reason you can only donate to AB+ recipients is due to your Rh factor being positive. It’s like the antigens if they don’t have it also, it will be rejected.

  6. I have A- blood type., i want to share something that happened to me , and couldve caused major problems with my unborn daughter at the time . Everyone who is Rh- knows that w have to get the rogham shot at 28 wks and after birth if your child has a positive blood type , i gonna Terry to make this short , i. Had gotten pregnant With My little one and was told that i had become sensitized. , which means , the rhogham shot no longer Worked for me , the shot would be senseless , not knowing my daughter’s blood type at that time , ii had to be monitered Very closey thru my whole pregnancy ,titers checked , talks about. What could happen , such as my LO Might need a blood
    transfusion. before and after birth . i was petrified , i didn’t understand how i. became sensitized., or what it even meant , had it explained , buti didn’t get it 100% In the end my titer levels stayed low and my lil one came out with A- like me , thank god. To the women. Who are rh negative., and are having kids the shot is VERY IMPORTANT. ‘after our first child mostly ‘ but accidents happen , if you are furtger than 28 wks and haven’t gotten the rho gham. Be sure to just remind., They said if you have a miscarriage or terminate a pregnancy., DO NOT forget to go back for check up , and get your after shot too. I still am not 100% sure on why i became sensitized , i believe it was a miscarriage., that i thought was my menstrual cycle , bc its always paibful. Just be aware and if anyone can refresh me on what it exactly means
    To be sensitized. I was told about antigens and titers and all kinds of different things, seriously never understood. 100%

    1. OA is a combination of O from one parent and A from another parent, the A cancels the O so your blood type is A in simple form because the A is dominant over O
