serum containing anti-A antibody is
dripped; on the seconcontaining anti-B antibody d lamina is dripped;serum (^)
on the third lamina serum with anti-RH
antibody reaction takes place is dripped. If no agglutinationin all of the laminae (^)
the blood is of type O- (universal
donor); if the first lamina thagglutination occurs oe blood is type A-;nly in
and so on.
There are other methods of bloodtyping. Blood typing must be performed (^)
by qualified technicians.
- What are the inheritance
and dominance patterns of the
Rh blood system?
The inheritance psystem is autosomal dattern oominant, i.f the Rh bloode., the (^)
heterozygous manifests as Rh+. The
dominance is complover r). The possible gete (R is doenotypes are RR,minant (^)
Rr (both Rh+) and rr (Rh-).
Curiosity:gene containing the Rh factor is2790 DNA codified by anucleotides
situated in the human chromosome 1.
- What is the logic of the
transfusional compatibility
concerning the Rh blood group
system?
An Rh+ donor can only donate blood to
an Rh+ rthe Rh factor (Rh-) can decipient. A person that lacksonate to
individuals of the Rh+ and Rh- groups.
- What is the Rh typing of
the mother and of the fetus in
the hemolytic disease of the
newborn?
In the hemolytic diseasthe mother is Rh- and the fetus Rh+. Ine of the newborn

The hemolyticis also known as e disease orythroblastosisf the new born fetalis. - How does the immune
process that causes the
hemolytic disease of the
newborn take place?
In the hemolytic diseasthe mother has Rh- blood. This mote of the newbornher
when generating her first Rh+ child
makes contact,with Rh+ red blood cells of the child an possibly during delivery,d (^)
her immune system triggers the primary
immune response against the In the next gestation in which thRh factor.e fetus
is Rh+ the mother will already have
much morcirculation; the anti-Rh antibodiese antibodies cross thees in her (^)
placental barrier and gain the fetal
circulation causin(destruction of the red blood cells og fetal hemolysis (^) f the
fetus).
- How can the hemolytic
disease of the newborn be
prevented?
Erythroblastosis fetalis can be prevented
if in the first dfrom a Rh- mother serum containinelivery of a Rh+ childg (^)
