It has confused some in the past unless they ran another typing system. Since I have vitiligo and look white they likely might run the wrong test. Then like ABO system I still might show something on the wrong test.
Some of the other types show people that are compatable with those on the ABO system. The closest thing they would resemble is an O type or being the same type. They may even falsely get labeled a golden type. They are not O and not golden. But their anitigens and such are quite different.
The factions in the war knew of the non ABO system blood types and their compatibility. But they wanted to handle their blood shortage on their own. They came up with their methods to try to do things.
Sometimes they were further disasters. A farm being used for the cow hybrid blood production test program was attacked by starving towns folk. The farmer and lab person argued for them to not touch the cows. But they were starving and all their cattle gone.
People didn’t want “dark” peoples blood. They were quite insulted to be offered it to be put in their bodies. This is even though it would save their lives.
They changed their minds and out of desperation kidnapped a bunch of people that were peaceful and not a war. They figured they were from poorer areas and would be missed less.
Some of them had once been their own people but sent as immigrants due to their population concerns. They had mixed with locals and became part brown or black.
To of just took the help of the people with black or brown skin would of been a quick answer. It would of saved l lives. But they didn’t want to use their medicine and called it primitive. Synthetic blood made from plants, might not of been well known but wasn’t primitive though it was an older practice. They refused to offer to donate blood after the abductions and racism.
Many rumors go around during times of war. People heard rumors of the twin babies. Stories of the hope babies. Stories of the golden children that would bring them eternal life. Some of course knew better about the eternal life but had superstitions about such things and about receiving donations of bodily products. Jehovah’s Witnesses are well known for the latter.
There is hapgroup specific medicine. Much of our medicine overlaps no matter the blood system used or hapgroup. But blood system ABO people tend to primarily fit X and Y hapgroups. X is quite large and only one of the “mother or Eve” groups. Sometimes more specific hapgroup medicine will save your life. Particularly if you are non-white, mixed ethnic heritage.
Some countries have banned asking heritage or sex(gender) on forms and say they are being socially progressive. That is not true. Knowing your physical sex and your likely hapgroups can save your life.
Knowing your possible hapgroups can decided which is the best blood systems to test for (to find the closest matches) and issues that are specifically male or female rather than general conditions that can affect both sexes.
Under the ABO system and hapgroups X/Y medicine I test as a chimera (ABO) and intersex. Under my proper ethnic testing I am one blood type(non chimera) and my tissue tests as androgynous female to regular female. I can test properly under two blood type systems. One of the hapgroups has androgynous and the other doesn’t.
My typing has been thoroughly done in other countries. This is because of military and police service as well as government work. If your in the military and in some police agencies they will type you for field medicine.
In the ABO system I had uniform patches to match my team depending upon my fellow team members. The Indian system doesn’t need them as both types can donated to each other but same type is preferred. The African groups sometimes do use patches.
