The world is slowly waking up to giving people an option to pick a partner amongst the large group of those who are blood type compatible. One of the most important reasons to know a future partner´s blood type is that the rhesus factor can decide whether or not there may be potential complications on the horizon when picking someone you plan to have children with.
See the article below highlighting the section about blood type compatibility:
New Delhi: Gone are the days when matching of horoscope intended to be the right practice for a successful marriage. These days, what doctors and medical experts are recommending is checking the medical compatibility of bridegroom.
Various young couples go for the medical compatibility tests as experts truly believe that watching the physical and medical health is more essential than matching kundalis.
The tests to check the medical compatibility include tests of Hepatitis B, Hepatitis C, knowledge of the blood groups, Thalassemia, sexually transmitted diseases, HIV and Tests for certain known Genetically Transmitted Diseases.
This is to mention here that the trend has been accepted by Indian couples and has now turned out to be a part of selection process in arrange marriages. Wedding therapists believe that even in love marriages people opt for the medical compatibility tests.
Here are the tests that need to be done under the medical compatibility of a couple before taking the plunge-
Blood Group Tests: When it comes to blood groups it is essential that you both have the same Rhesus factor (Rh factor). If your blood group is O positive and your partner has a blood group of B negative, he or she has a negative Rh factor. This information is essential especially during pregnancy, as a mother and baby of opposite Rh factors could lead to severe complications and even death of the baby.
Tests for genetically transmitted conditions: The test is important to check if you or your partner carries any genes that could manifest as a disease in your children. This includes conditions like thalassemia (a genetic blood disorder where a baby cannot produce enough red blood cells and will need a blood transfusion very often), cancers, juvenile diabetes, mental disorders, etc.
Tests for sexually transmitted diseases: There might a certain stigma attached to this test, but it is best that you both know your health status when it concerns these diseases. While HIV is life threatening, other STDs like hepatitis C, herpes, gonorrhoea, etc. are something you will have to live with all your life; not to mention the risk of your child getting affected by it.

The antigens living on the surface of your red blood cells can determine a lot more than just who you can donate to.
Blood type is one of the body’s more mysterious taxonomies. There are four bins our blood call fall into — A, B, AB, and O — and together they represent the four groups of antigens found on the surfaces of red blood cells. But they don’ t just signal who we can donate to and receive from; our blood types can reveal complex patterns of personal health. Here are six to consider:
1. Memory Problems
Your brain and vascular system have more in common than you may think. A recent study found people with type AB blood were 82 percent more likely to experience difficulties with memory recall, language, and attention than people with other types. One reason, researchers suspect, is due to the key clotting protein, known as coagulation factor VIII, which may actually reduce the quality of blood flow to the brain, rather than sealing up injury sites.
“Since factor VIII levels are closely linked to blood type, this may be one causal connection between blood type and cognitive impairment,” said Mary Cushman, author of the recent study, to Yahoo Health.
2. Pancreatic Cancer
It may be more accurate to say people with type O blood are at a lower risk for pancreatic cancer, given the work researchers from Yale University are doing on bacterial infection. In a study conducted last July, scientists from the University’s Cancer Center looked at cases of a common species of bacteria called Helicobacter pylori, or H. pylori, that lives in people’s gut.
They found people with H. pylori were significantly more likely to develop pancreatic cancer, due to the way A and B antigens help the bacteria thrive. People with type O blood carry no antigens on the surface of their red blood cells. This is what allows them to donate to anyone.
3. Heart Disease
A 2012 study from Harvard University found people with non-O blood also happen to have an increased risk for cardiovascular disease. But those with type AB blood were the most at-risk overall, demonstrating a 23 percent greater chance of suffering from heart disease than type O subjects.
Study author Dr. Lu Qi, an assistant professor in the Department of Nutrition, said the particular makeup of people’s antigens should be given the same weight we already assign to cholesterol and blood pressure. “While people cannot change their blood type, our findings may help physicians better understand who is at risk for developing heart disease,” Qi said in a statement.
Because certain blood types are more likely to co-occur with varying levels of hormones in the body, physicians commonly tailor their exercise recommendations to the patient’s type. People with type A blood, for example, are more likely to have higher levels of cortisol, the stress hormone, in their body. So, stress-reducing exercises, like Tai Chi and yoga, may be more beneficial at cutting that tension than running or weightlifting alone.
When the adrenal gland dumps more and more cortisol into the blood, people’s stress response grows more acute. People with type A blood may find themselves getting anxious more quickly and having a harder time letting troubles roll off their back.
5. Exercise Demands
More generally, the makeup of a person’s antigens on his or her red blood cells can determine how much of a certain hormone gets released. People with type A and B blood respond better to calming, low-intensity exercise like yoga, especially if depression runs in the family. Likewise, people with AB blood benefit from well-rounded workouts that keep their immune systems in check. Type O people, however, are a different story.
“Type O’s are more prone to problems that arise from an inability to clear stress hormones from their system quickly,” Dr. Ginger Nash, a naturopathic physician, told Personalized Living. “It takes more to get a Type O stressed but it takes more to de-stress them as well.”
6. Gut Bacteria
In addition to living on your red blood cells, antigens are often found in the lining of your digestive tract — about 80 percent of people fall into this category. Much of the bacteria living in people’s gut uses these antigens as food, which largely determines which bacteria flourish and which disappear. Prior research has estimated, for instance, that people with type B blood contain up to 50,000 times the number of strains of friendly bacteria than people with either type A or O blood.
“Increasingly, studies are showing that changes in the microflora content of the digestive tract can be linked to metabolic illnesses, including type II (adult onset) diabetes and obesity,” wrote Dr. Peter D’Adamo, physician and author of Eat Right 4 Your Type, in a blog post. “Blood group and secretor status play an important role in conditioning the overall characteristics of the digestive tract.”
Objective: To assess the relationships among ABO group, factor VIII (FVIII), and incident cognitive impairment in a large, prospective cohort study of black and white adults in the United States using a nested case-control design.
AB is the least common blood type, found in about 4 percent of the U.S. population. The study found that people with AB blood were 82 percent more likely to develop the thinking and memory problems that can lead to dementia than people with other blood types. Previous studies have shown that people with type O blood have a lower risk of heart disease and stroke, factors that can increase the risk of memory loss and dementia.
Methods: Incident cognitive impairment was defined using cognitive domain tests over a mean follow-up of 3.4 years. ABO blood group was measured by genotyping in a nested case-control sample of 495 cases with cognitive impairment and 587 controls.
Results: Those with blood group AB and those with higher FVIII had an increased risk of cognitive impairment, adjusting for age, race, region, and sex (respective odds ratios 1.82, 95% confidence interval [CI] 1.15–2.90; and 1.24, 95% CI 1.10–1.38 for 40 IU/dL higher FVIII). Mean FVIII was higher in those with blood type AB (142 IU/dL; 95% CI 119–165) compared with O (104 IU/dL; 95% CI 101–107), and FVIII mediated 18% of the association between AB group and incident cognitive impairment (95% CI for mediation −30% to 68%).
“Journey to Babel” was the episode where Spock needs to save his father´s life as he has the same rare blood type as him:
Marriages worldwide are following the same trend: people are getting married later – or not at all. But while following the same trends, marriage still looks very different across the globe.
The above map uses data from the UN to show the average age at which people get married by country. Since the UN draws its data from different surveys done on a country by country basis, the data is not always from the same year.1
The biggest differentiator of marriage age seems to be a country’s income, with people in developed countries marrying later. Nordic countries and Western Europe rank among the highest for mean age at marriage at above 30 years. Afghanistan has one of the lowest at 20.2 years.
Averaging the marriage age of entire populations hides the fact that men get married much later than women. This is true in every country. The gender age gap for marriage is wider in less developed countries: women get married 8.3 years earlier in Afghanistan to 1.8 years in France, for example. As we see in the below graph of worldwide averages of mean age of marriage, the gap has narrowed only slightly over the past 35 years.
Source: United Nations World Marriage Data 2012
It remains common today for women to marry very young in some developing countries. Thirty nine countries have data showing that 20% of women married by age 18. In twenty countries, a full 10% of women married by age 15. In only 2 countries, however, are 10% of men married before the age of 18. Still, men and women are getting married later in every region of the world. The average age of marriage for women increased from 21.8 to 24.7 years from the seventies to the mid 2000s, with the average age for men rising a comparable amount.
This has resulted in some fairly dramatic stats here in the United States. Today, less than half of American adults are married – down from 72% in 1960 – and almost as many babies are born out of wedlock as to married couples.
Nevertheless, around the world the majority of people still get married, even if they get married later. In all but a dozen or so countries, 80% of men and women have been married by age 49, and even more people commit to comparable or similar “consensual unions.” Despite all the global differences and changes, shacking up is still the norm.
If not, you may suffer from this:
Some messages need to be repeated. And this is one.
But little do many know in regards to the WHY:
If you are blood type O, you are more likely to be a secretor than other ABOs.
By secretor it indicates that you carry your blood cells in your saliva and sweat.
That means mosquitoes can smell and sense you.
This is just one of many reasons why knowing your blood type is so important.
These links between blood types and diseases have a mysterious arbitrariness about them, and scientists have only begun to work out the reasons behind some of them. For example, Kevin Kain of the University of Toronto and his colleagues have been investigating why people with type O are better protected against severe malaria than people with other blood types. His studies indicate that immune cells have an easier job of recognising infected blood cells if they’re type O rather than other blood types.
More puzzling are the links between blood types and diseases that have nothing to do with the blood. Take norovirus. This nasty pathogen is the bane of cruise ships, as it can rage through hundreds of passengers, causing violent vomiting and diarrhoea. It does so by invading cells lining the intestines, leaving blood cells untouched. Nevertheless, people’s blood type influences the risk that they will be infected by a particular strain of norovirus.
The solution to this particular mystery can be found in the fact that blood cells are not the only cells to produce blood type antigens. They are also produced by cells in blood vessel walls, the airway, skin and hair. Many people even secrete blood type antigens in their saliva. Noroviruses make us sick by grabbing onto the blood type antigens produced by cells in the gut.
Yet a norovirus can only grab firmly onto a cell if its proteins fit snugly onto the cell’s blood type antigen. So it’s possible that each strain of norovirus has proteins that are adapted to attach tightly to certain blood type antigens, but not others. That would explain why our blood type can influence which norovirus strains can make us sick.
It may also be a clue as to why a variety of blood types have endured for millions of years. Our primate ancestors were locked in a never-ending cage match with countless pathogens, including viruses, bacteria and other enemies. Some of those pathogens may have adapted to exploit different kinds of blood type antigens. The pathogens that were best suited to the most common blood type would have fared best, because they had the most hosts to infect. But, gradually, they may have destroyed that advantage by killing off their hosts. Meanwhile, primates with rarer blood types would have thrived, thanks to their protection against some of their enemies.

If you don´t know your blood type, contact your physician, donate blood or order a testing kit online.
Sperm donation is also used in cases of rhesus incompatibility. This particularly occurs where a woman has a blood type which is rhesus negative, and where her partner is rhesus positive. The woman’s body may reject a fetus if it has rhesus positive blood. Anti D injections have been developed and may be used to attempt to avoid this, and these are usually automatically given to rhesus negative women immediately after they give birth to their first child. However, in the past this was either not possible or was not always routinely undertaken where a woman gave birth or had an abortion and she may have trouble carrying a child later in life. Furthermore, for some women, the anti D injection does not provide the entire solution, particularly where there is a medical history of complications during pregnancy which risk the woman’s blood and that of the fetus becoming mixed. In such cases, sperm from a rhesus negative donor can provide the solution and a woman may be able to conceive and carry a pregnancy to full term when otherwise this would not be possible. For this reason, sperm from rhesus negative sperm donors is often in great demand, particularly those with the O negative blood group who are universal donors.
