rh positive
Definition
Noun: A blood group classification in which an individual's red blood cells possess the Rh factor (Rhesus factor), a specific antigen on the cell surface. This is the most common blood type among humans.
Usage
This term is used primarily in medical, biological, and healthcare contexts to describe a person's blood type. - It is often written with a plus sign (+) following the ABO blood type (e.g., O+, A+, B+, AB+). - It is the opposite of Rh negative.
Examples
Advanced Usage
- Rh Positive Blood: Refers to the physical blood that contains the Rh antigen.
- The transfusion must be matched; Rh positive blood cannot be given to an Rh negative recipient.
- Rh Positive Individual/Person: A person who has this blood type.
- As an Rh positive individual, he can receive blood from both Rh positive and Rh negative donors.
Variants and Related Words
- Rh factor (noun): The specific antigen (protein) present on red blood cells that defines Rh positive status.
- Rhesus factor (noun): Another name for the Rh factor, derived from the Rhesus monkeys in which it was first identified.

Notes
- The term itself is not typically used in idioms or phrasal verbs due to its specific technical nature.
- In everyday conversation, people usually state their full blood type (e.g., "I'm A positive") rather than saying "I am Rh positive" alone, though the latter is medically accurate.
Noun
-
the blood group (approximately 85% of people) whose red cells have the Rh factor (Rh antigen)
