is a protein that can be found on the surface of red blood cells
The Rh factor
other name for RH factor
rhesus factor
rhesus, factor was discovered in
1940
who is the discoverer of RH factor
K. Landsteiner and A. S. Wiener
A person with the Rh factor on his or her red blood cells is said to be
Rh-positive (Rh+ ).
Since this person has the factor, he or she will not make
anti-Rh antibodies.
A person without the Rh factor on their red blood cells is said to be
Rh-Negative (Rh- ).
if RH negative This person WILL produce
anti Rh antibodies.
If mother is Rh- and the fetus is Rh+, A condition called
Erythroblastosis Fetalis
Rh Antigen, also called
Rhesus antigens
are transmembrane proteins expressed at the surface of erythrocytes.
Rhesus antigens
The Rh antigens are inherited as a genetically linked group known as
a haplotype.
Rh antigens are highly immunogenic, the ___ antigen is most potent
D
Exposure to less than 1 ml of Rh-positive red cells can stimulate
Ab production in an Rh-negative person.
is an inherited protein found on the surface of red blood cells.
Rhesus (Rh) factor
determines the expression of the D antigen
RHD gene
determines the expression of the C, c, E, and e antigens
RHCE gene
is one of the most polymorphic and immunogenic systems known in humans.
Rh blood group system
the second most important system.
Rh system
is the most common cause of severe HDN and can cause in Utero death.
anti-D
A problem can occur when a woman who has Rh-negative blood becomes pregnant with a baby that has Rh-positive blood. This is called
Rh incompatibility
If the blood of an Rh-positive baby mixes with the blood of an Rh-negative mother during pregnancy or delivery, the mother’s immune system makes antibodies. This antibody response is called
Rh sensitization
PUFT
Para-perirenal ultrasonographic fat thickness
NSVD
Normal spontaneous vaginal delivery
