how many types of blood group are there - #36760
I am really confused about something health-related and need some help. I was doing some research on blood groups – specifically how many types of blood group are there – and I came across conflicting info. Like, I thought there were just the usual A, B, AB, and O, right? But then I read about different subtypes and Rh factors and honestly, I’m lost. Last week, I went to donate blood for the first time and that’s when they asked about my blood group. I just froze because I realized I never really knew much about my own blood type! I mean, I thought I was O, but then they said something about being O+ and I just didn’t get it. To make things worse, my mom keeps saying how knowing how many types of blood group are there is super important for health reasons and transfers, and I started feeling panicky. Is it really as critical as she says? Like, if I can’t remember my blood group, does that affect me? Just trying to wrap my head around all this. Can someone explain it to me? Are there really so many types of blood group that it gets complicated?
