5 Questions
What determines blood typing?
Presence of A or B antigens and Rh factor on the surface of blood cells
What does the positive or negative sign next to the blood groups indicate?
The presence or absence of the Rhesus (Rh) factor
What is the Rh factor?
An inherited protein found on the surface of the red blood cell
What does it mean if someone has Rh-negative blood typing?
Their blood cells lack the Rh protein
How does having a Rh-negative typing affect health?
It usually doesn’t affect health
Study Notes
Blood Typing
- Blood typing is determined by the presence or absence of specific antigens on the surface of red blood cells.
Rh Factor
- The Rh factor is a type of antigen found on the surface of red blood cells in most people.
- The presence or absence of the Rh antigen is indicated by the positive or negative sign next to the blood group (e.g. A+, A-).
Rh-Negative Blood Typing
- If someone has Rh-negative blood typing, it means they do not have the Rh antigen on their red blood cells.
- Rh-negative individuals may produce antibodies against the Rh antigen if they receive blood from an Rh-positive donor, which can lead to complications.
Health Effects of Rh-Negative Blood Typing
- Having Rh-negative blood typing generally does not affect health, but it can cause complications during pregnancy or blood transfusions if not properly matched.
- Rh-negative mothers may require medication to prevent their immune system from producing antibodies against the Rh antigen in the fetus.
