One of the first tests a pregnant woman should expect is a blood-type test. This test checks her blood type and Rh factor. Her Rh factor may play a role in her baby’s health, so it’s important to know this information early in pregnancy. An Rh factor is a protein found on some red blood cells RBCs.

Your Blood Type is a Lot More Complicated Than You Think

Not long ago, a precious packet of blood traveled more than 7, miles by special courier, from America to Australia, to save the life of a newborn. Months before the delivery date, a routine checkup of the mom-to-be had revealed that the fetus suffered from hemolytic disease. Doctors knew that the baby would need a blood transfusion immediately after delivery. The problem was, the baby’s blood type was so rare that there wasn’t a single compatible donor in all of Australia.[rs_table_products tableName=”Best Dating Websites”]

A request for compatible blood was sent first to England, where a global database search identified a potential donor in the United States. The ARDP had compatible frozen blood on hand, but Nance knew that a frozen bag might rupture in transit. So her organization reached out to the compatible donor, collected half a liter of fresh blood, and shipped it across the Pacific. When the mother came in to give birth, the blood was waiting. For the sake of simplicity, these are the types that organizations like the Red Cross usually talk about.

But this system turns out to be a big oversimplification. Each of these eight types of blood can be subdivided into many distinct varieties. There are millions in all, each classified according to the little markers called antigens that coat the surface of red blood cells. There are in fact hundreds of antigens that fall into 33 recognized antigen systems, many of which can cause dangerous reactions during transfusion.

Try fitting that into that little space on your Red Cross card. Scientists have been discovering unexpected antigens ever since , when two New York doctors transfused type O blood into a young woman at Bellevue Hospital. After running some lab tests, the doctors confirmed that even type O blood could contain previously unknown antigens. Additional kinds of antigens have been discovered every few years since then. Almost everyone has some.

More than For every 2, people, there’s one who lacks the Vel antigen who shouldn’t receive blood from the remaining 2, If a Vel-negative patient develops antibodies to Vel-positive blood, the immune system will attack the incoming cells, which then disintegrate inside the body. For a patient, the effects of such reactions range from mild pain to fever, shock and, in the worst cases, death. Blood types are considered rare if fewer than 1 in 1, people have them. One of the rarest in existence is Rh-null blood, which lack any antigens in the Rh system.

If your blood is Rh-null, there are probably more people who share your name than your blood type. And if you receive blood that contains Rh antigens, your immune system may attack those cells. In all, around 20 antigen systems have the potential to cause transfusion reactions. Just to be clear, transfusion patients today don’t have much to worry about. In , there were tens of millions of transfusions in the United States, but only a few dozen transfusion-related deaths were reported to the U.

Food and Drug Administration. Medical practitioners go to great lengths to make sure that transfused blood is compatible. But curiously enough, they manage to do this without even knowing all the antigens present. If the two samples clump, the blood may be unsafe to transfuse. Figuring out the precise cause of the problem is like solving a crossword puzzle, she says. This was the process that helped the newborn in Australia. Lab technicians there had tested the fetal blood and figured out which antigens they needed to avoid.

But they still didn’t know where in the world they might find suitable blood. So they sent a rare blood request to the international organization set up for cases just like this: The IBGRL consults its database of hundreds of thousands of rare donors worldwide to find compatible blood. For the past 30 years, the process of global blood sharing has been gradually standardized during the biennial congress of the International Society for Blood Transfusion, which took place this week in Seoul, South Korea.

Many more are shipped within national borders. In , for example, more than 2, units of rare blood were shipped within the United States. Even rare donor programs with the resources to identify and ship rare blood are looking to improve. There just aren’t enough rare donors who come in regularly. The American Rare Donor Program has 45, rare donors in its database, but 5 percent of transfusion patients still don’t get the blood they need. Coral Olsen, a scientist in charge of regional rare blood banking in South Africa, says that her laboratory often struggles to keep track of registered rare donors.

So that’s our challenge, as far as tracing and tracking and maintaining our rare donor base. For many countries, an even bigger challenge is simply dealing with resource constraints. National blood laboratories have to maintain a repository of samples if they want to run detailed antigen tests. Finally, there’s the high cost of importing rare types, especially for patients who need chronic transfusions.

In those cases, medical professionals sometimes have to use blood that’s known to be incompatible, but unlikely to cause severe reactions because of the particular antigens involved. One day, scientific breakthroughs may make it easier to find compatible blood for anyone. Geneticists are working on testing methods that determine blood types using DNA, without looking at the blood itself. So far, this process only works with certain antigens.

Nance hopes that one day, every newborn will undergo testing so that blood banks can build a comprehensive database of every rare type, which would immediately point medical professionals to the nearest compatible donor. Until then, researchers will probably go on discovering antigens one by one. It’s as if the surface of red blood cells started out as a fuzzy picture that scientists have slowly brought into focus, revealing subtle differences that just weren’t visible before.

For blood scientists and patients with rare blood types, these differences can be tedious and troublesome. But they’re also a reminder of our remarkable individuality. With hundreds of possible antigens and millions of possible antigen combinations, your blood can be as unique as your fingerprint. Subscribe or Give a Gift. Sign up. SmartNews History.

There is also an antigen called the Rh factor. If you have the Rh factor on your cells, you are Rh positive. There is a 15 percent chance that you are Rh negative. Being Rh negative has no effect on general health, but can cause problems during pregnancy. People who are Rh negative can make antibodies if exposed to Rh positive blood. This can happen during pregnancy or with a blood transfusion. If this happens, antibodies can form. Antibodies are proteins the body makes to protect itself when it reacts with something that is foreign. If a woman is pregnant and Rh negative and her partner is Rh positive, she is at risk for making Rh antibodies. It will help protect your baby and any future pregnancies. Once your body makes antibodies, they do not go away. Every time you get pregnant, the risk to your baby is more serious.

There is a vast span of human existence of which little is known. Archeological ruins from the beginnings of civilization have been unearthed, and there have been occasional discoveries of a more prehistoric nature, but not much else. The impermanency of our physical existence is responsible for this void; our flesh and body fluids rapidly decompose after death. Unless preserved by extraordinary means, even skeletal remains eventually crumble and disappear. Early peoples did not practice ceremonial burial.

The Most Precious Blood on Earth

Blood banks run blood type tests before blood is sent to hospitals for transfusions. The ABO blood group, as the blood types are collectively known, are ancient. But why humans and apes have these blood types is still a scientific mystery. Through a series of experiments, Landsteiner classified blood into the four well-known types. An antigen is anything that elicits a response from an immune cell called an antibody. Antibodies latch onto foreign substances that enter the body, such as bacteria and viruses, and clump them together for removal by other parts of the immune system. The human body naturally makes antibodies that will attack certain types of red-blood-cell antigens.

There are a bunch of weirdo sites out there about their origin. My blood type is A negative. I’ve heard this can cause pregnancy issues, so I Googled “Rh-negative blood” and ran across a bunch of weirdo sites with “theories” about the origin of negative blood types and some online communities with seriously racist undertones. Where did all this crazy mythology surrounding blood types come from? Many links concerning Rh-negative blood look kosher enough in your search results but when clicked release a flood of wide-eyed theories about ethnic migration, blood-type-based dating tips, and offers to trace your ancestry back to extraterrestrials, angels, or lizards.

His doctor drove him over the border. It was quicker that way: If the man donated in Switzerland, his blood would be delayed while paperwork was filled out and authorizations sought. The nurse in Annemasse, France, could tell from the label on the blood bag destined for Paris that this blood was pretty unusual. But when she read the details closely, her eyes widened. Surely it was impossible for this man seated beside her to be alive, let alone apparently healthy? Thomas smiled to himself.
