The “negative” is RH. A negative is RH negative also.

A-,B-,AB- and O- are all RH negative. A+, B+, AB+, and O+ are all RH positive.

RH is a factor that can be present with any of the blood types. (It’s actually more than one factor; it’s any of a number of proteins that, if present, can cause a severe immune reaction if transfused into someone without the factor.)

thanks so much, i will look into it more…. so rh isn’t a stand alone type it’s a factor within types if that makes sense?

so does all blood have RH in it?
why would someone say i’m RH negative?

@tan235 no, not all blood has RH in it. RH negative means you don’t have RH proteins in your blood. RH positive means you do.
