Have you ever heard the word blood types? If you haven't, those types are simply ways of defining some different values of blood. Why would you need to do this? You need these type of values - which I am not going to go into, here, because it's kind of off-topic as to this article - in order to ascertain whether you can use blood, that has been donated by a person, to fill another person's body with it; and if you wouldn't be able to see if the blood type values were the right ones, filling blood into the person's body would be nothing else than a gamble; considering the fact that the person could die if the wrong type of blood was inserted. On this note, enter rare blood types. These are ones that are especially hard, for the hospitals, to find. They are hard to find, because they are rare - obviously. These rare blood types are types of blood that less than one in two hundred donors will supply.

Obviously, these rare blood types cause big stress with hospitals - and, possibly, more with smaller ones then the large ones; as in smaller ones you don't have that many people donating, meaning you aren't as likely to find rare blood types as you would be in a larger hospital.

I see here, on a chart of how many possess the different blood types in different countries, that AB- is the most rare one of the rare blood types. It is consistently so, whatever country you are looking at (at least out of the countries presented on the chart). AB- ranges from being present in 0.1% of all people to being present in 1% of all people. You have a country, here, in which a lot of the blood types are very uncommon. Or, rather, in which the most blood types could be classified as rare blood types. This country is Taiwan. I see here on the chart that, one in five thousand people possess the AB- blood type. But, actually, the next one - which is, in most of the other cases the second to most rare blood type - is the most rare one in Taiwan. This one is only present in one in ten thousand persons. The next blood type is present in one in a thousand people, and so is the next one. These numbers are staggering, considering in every other case - at least as presented on this chart - none of the other countries would have more than one of the blood types classified as rare blood types (except for one).

I hope that you have found this little guide to rare blood types to be of value, and as great a read as it could possibly be seen as. I want to thank you for reading, here, a little about rare blood types.
