Question 1

if a fetus has an rh negative mother and an rh positive father, will a miscarriage occur?

Accepted Answer

Not if first preg.: Rh sensitization usually occurs  after delivery of a child who is Rh +, and mom is -.   Fetal blood may mix with maternal blood. If not given Rhogam (antibodies against Rh + blood)  her immune system will be sensitized to Rh+.  Fathers who  are Rh+ may be carriers of Rh - , with 50% chance of an Rh - infant with no risk. Even if sensitized, fetal therapy can allow survival of an Rh + baby.

Question 2

docs, could a o positive mother and an o negative father have a child that is rh negative?

Accepted Answer

Yes: They could also have one that is rh positive.

Question 3

what happens if a mother is rh negative and has an rh positive baby?

Accepted Answer

Father jean: Rh positive is from the father jean.

Question 4

rh negative and the baby's father is rh positive. do i need rhogham?

Accepted Answer

Possibly: With an rh neg mom and an rh pos dad it is possible for your baby to be either rh pos or neg.  It will be necessary for the baby to tested after birth and administer Rhogam if he/she is rh positive.  The odds of an rh neg baby in this scenario range from zero to 1 in 4.

Question 5

im rh negative and the baby's father is rh positive so what do we do?

Accepted Answer

Only if you are Rh+: Rh positive mothers having  rh+ babies-no problem! rh negative mothers with a rh+ baby especially the first and subsequent pregnancies will require Rhogam injection post delivery to prevent future rh disease issues and baby losses.

Question 6

rh negative and not sure who the baby's father is. odd are rh positive like 85% of the population, right?

Accepted Answer

Correct: Because you are rh negative, you should be offered Rhogam at 28 weeks and after delivery if the baby is rh positive.  Also, there are some other situations where Rhogam may be given, but they are less common.

Question 7

my mother is a+rh positive and so is my dad, my blood type is a-rh negative. how is this possible?

Accepted Answer

Recessive genes: If each of your parents has one rh + and one rh- gene, they will both produce the rh antigen. But each of their offspring has a one out of four chance of inheriting the negative gene from both parents, which makes them (you) rh neg.

Question 8

my father is a+, my mother is a-. my mother is rh negative.
im trying to make sense of things. im a- rh negative. is this possible?

Accepted Answer

Yes: That sounds fine. In such a scenario, if you had many siblings, some would be Rh positive and some would be Rh negative.

Question 9

is it possible to have child with rh negative blood if both parents have blood rh positive?

Accepted Answer

Yes: The rh factor is determined from both parents. Each parent contributes one half of the infant's rh type. Each parent has 2 rh genes. So, if each parent (of the child in question) has a "split" rh:(-)/(+), i.e. Half negative and half positive--they are reported as "positive". Yet if each parent contributes the "blank" or rh negative portion to baby then he is (-)/(-) or rh negative!

Question 10

what could happen if an rh negative person were given a blood transfusion of rh positive blood?

Accepted Answer

Antibody formation: At the first transfusion, nothing happens, but the person generally makes antibodies to Rh antigen and may have a transfusion reaction at the subsequent transfusion with Rh positive blood. If it is  a woman of reproductive age and the baby is Rh positive, the baby may get hemolysis.
