how many type of blood - #22824
I am kinda worried here. The other day, I heard my friend talk about how many type of blood there are and he mentioned something like 4 or 5? I have no clue, honestly. Last week, I went to the doctor for some routine tests and they said something about needing to check my blood type. I was just thinking, is it really that important to know how many type of blood there is? I mean, when I learned about blood in school, we covered A, B, AB, and O. But then I saw something online about Rh factors and how there’s like positive and negative variations. Ugh, it gets really confusing. Can someone tell me how many type of blood are out there? Does it really make a difference for everyday life, or is it just critical in situations like transfusions? I'm just trying to piece this all together, you know? My cousin needed blood last year and it took ages for them to find a match. If they have like a super rare type in the mix, how does that work? I really hope I don't have a super rare type because that sounds scary. I’m just trying to understand how many type of blood really matter. Thanks for any info!
