In brief: It's the same thing

In the abo/rh blood typing categories, if the rh factor is not there, it is called a negative blood type.
(in other situations, when doctors are not talking about the abo/rh typing, then "negative" would mean that something else is missing. For example, a test for sickle cell anemia would be called "negative" if no sickle cell mutation was found, but would not be talking about the rh factor.).
