"Rh-negative" Pronounce,Meaning And Examples

"Rh-negative" Meaning

A term used in medicine, particularly in blood transfusion and genetics.

Rh-negative refers to a person's ABO blood type, specifically the Rhesus blood type system. In this system, individuals can be classified as Rh-positive (Rh+) or Rh-negative (Rh-). The "Rh" refers to the Rhesus monkey in which the antigen was first identified.

A person with an Rh-negative blood type lacks the RhD antigen on their red blood cells. This can be a factor in medical transfusions, as Rh-negative blood is generally only compatible with other Rh-negative blood. If an Rh-negative person receives a transfusion of Rh-positive blood, their immune system may react and produce antibodies against the Rh antigen, which can potentially cause complications in future transfusions.

Rh-negative blood is relatively rare, occurring in about 15% of the global population, although the frequency varies widely depending on the population. In the United States, for example, approximately 15% of Caucasians are Rh-negative, while around 1% of African Americans are Rh-negative.
