People who have Rh- blood lack the D antigen, which is the most important in terms of determining donor-recipient matches, so more accurately they are RhD-. On the other hand, Rh(null) people have none of the Rh antigens, meaning that any blood they receive from the majority of donors would elicit an immune response.When it comes to the curb appeal of your home, even the details that most people neither care nor even notice can actually have a major effect.

Rh factor (or Rhesus factor) is a type of protein on the outside or surface of your red blood cells. You inherit the protein, which means you get your Rh factor from your biological parents. If you have the protein, you’re Rh-positive. If you don’t have the protein, you’re Rh-negative. The majority of people, about 85%, are Rh-positive. The RH-null phenotype designates rare individuals whose red blood cells lack all Rh antigens. Two RH-null types, the regulator type (RHNR) and the amorph type (RHNA; 617970), arising from independent genetic mechanisms have been distinguished.
