you've never given blood, never were transfused and no one has ever told you what your type is. This may sound silly coming from someone who has paid attention to her meds and care pretty carefully. But, I just never knew what my blood type was. My parents were not the best record keepers. The only surgery I ever had that could have been a threat to my blood supply was an emergent surgery so it was not something I checked in advance.
We did a check in high school biology (oh so many years ago) and I was O+. But how accurate could that have been considering no one was taking the class that seriously back then.
So is it a lab test that my doc does, can he just do it in his office? How do I find out?
