Given the four main blood groups (A, B, AB, and O) and two Rh factors for each (positive or negative), there are a total of eight blood types. If your blood has proteins, you’re Rh-positive.
O NEGATIVE BLOOD TYPE COVID RESISTANT CODE
Type A carries anti-B antibodies only type B carries anti-A antibodies only type AB carries no antibodies.Īlong with the letter code for blood types, there’s also a Rhesus factor, or “Rh,” which is an inherited trait. A blood type is said to be “positive” or “negative” depending on whether there are proteins on the red blood cells or not. On that point, type O blood carries both anti-A and anti-B antibodies in the plasma. (Antigens are substances which induce an immune response, particularly in the production of antibodies.) A person with type O blood doesn’t produce any antigens.
Type AB blood, on the other hand, would result in both A and B antigens being produced on red blood cells. If you have type A blood, your body is programmed to produce the A-type antigens on red blood cells. The letters A, B, and O represent different variants of the ABO gene, which is what programs our blood cells to form the different blood groups. Here’s a quick refresher for those who may have long forgotten those anatomy and physiology courses taken long ago. Need a blood transfusion? Are you donating blood? Going through pregnancy? Then you’ll likely find out in a hurry why your blood type actually is a matter of well-hidden importance. Many people never find out their type until it becomes necessary for one reason or another, and in reality, your blood type doesn’t really matter that much – that is, until it does.
You can’t tell by looking at a person, but each of us has a defined blood type running through our veins. Some studies suggest Covid-19 might be one of them, but a conclusive answer is much less clear.ĭo you know your blood type? Depending on what it is, you might have an increased risk or a reduced risk for certain illnesses or health conditions. It’s accepted science that people with certain blood types have a lower risk for a number of various illnesses.
