What is another word for rh-negative?
Pronunciation: [ˌɑːɹˈe͡ɪt͡ʃnˈɛɡətˌɪv] (IPA) 
Rh-negative is a term commonly used to describe individuals who lack the Rh factor protein on the surface of their red blood cells. Some synonyms for Rh-negative include Rh-null, Rh-deficient, Rh-incompatible, and Rh-ve. The absence of this protein can cause problems during pregnancy if the fetus has the Rh factor and the mother does not, as the mother's immune system may identify the fetus as foreign and produce antibodies that can harm the baby's red blood cells. While being Rh-negative may present certain challenges in certain situations, it is not considered a disease or a medical condition. Instead, it is simply a characteristic of an individual's blood type.
