I need help...

I really need to know this... please, if anyone can help me out, I’d be so grateful. It’s about blood types, specifically
A1 Verizon negative
and A Verizon negative
is that actually the same thing or am I looking at two different groups? ?????????????
Thanks a million in advance... seriously, THANK YOU.....

What do you mean by an A1 blood type? 😕
There are actually four main blood groups out there: A, B, AB, and O.
Then you’ve got the Rh factor, which is either positive or negative.

Here’s the lowdown on blood types:
